T5 Autoflower Room - Day 55 - Russian Rocket Fuel, Red Dwarf, Syrup & DeimosPlants are budding great but just like with our last auto-flower grow we seem to be running into deficiency problems. Leaves were yellowing, purple stems and even some rust spots? We were only running 50 percent flowering nutes and after a few weeks of flowering the plants started discoloring. We are going to increase feedings to see if that helps. PH has been consistent at 6.5 with our EC approaching 2.0. We may try running some organics with the autos next time because this could just be a rea

    @ArizonaMMJ Which Blackstars did you get? And what spectrum options did you guys go with? I don’t think I could get a better spectrum for my T5, maybe? But the Quantum spectrum is amazing,I can’t believe the speed and health and size of the growth I get.My only complaints with T5’s is their size and they still pull about the same amount of amps as HID lighting,they just run slightly cooler.For 1/4 of the amps, I can run LED with same results (except flowering maybe?) with no heat.

  2. TheBushDoctors says:

    @LEITHWALKNINJA I think there is some calcium deficiency going on, probably a little of everything to be honest since we have only been running feedings at half strength. A few plants leaves are turning dark green but most are turning light green as if deprived for food.

  3. ArizonaMMJ says:

    Did you say you’re gonna move away from T5 and just go to the HPS?

    Also did you prefer the Cap or the Titan for co2 and overall controller?

  4. ArizonaMMJ says:

    I hear you. We have tried the Blackstars and they are great for Veg. Horrible for flower. Our friends are trying the HydroGrow and Penetrator lED now for flower and it’s also disappointing. You should give T5 more try but with better bulbs and a better spectrum.

    You need Aquarium bulbs.

  5. TheBushDoctors says:

    @italianbc Thanks.

  6. TheBushDoctors says:

    @isofaster Thanks. Some have us a little worried but we are pretty happy for the most part.

  7. TheBushDoctors says:

    @ArizonaMMJ But a lot of people have problem with LED’s because they buy what they think are full spectrum bulbs (the ones that put off a purple pinkish look) are actually not full spectrum. They contain all of the spectrum but not in the same proportions as the sun. They do not work well for veg (its a red based spectrum) so therefore you cannot expect to do well in flower without a proper vegged plant. It took me a while to understand this marketing scheme.


    @TheBushDoctors yeah just with the rust spots,and t=it should go dark green if its c deficincy.hope ya get it soeted

  9. TheBushDoctors says:

    @bt4b4 They are not N deficient. And our Magical has been running double the dose but it has helped. I think just stepping up feeding should fix the problem. Feed at 50% every three days doesn’t seem to ever be enough for the auto-flowers with this line.

  10. ArizonaMMJ says:

    @TheBushDoctors I hear ya. I liked them for Veg but Flowering they fall short unless you have 1000’s of watts going over a very small amount of plants. Doesn’t work for commercial production at all.

  11. Rapnzapper says:

    We donneed no stinking nitrogen……

  12. 2dogarage says:

    maybe continue nitrogen longer or introduce periodically during flower, maybe needs more micronutes during the longer flower, some people introduce food into the water every time, big mistake. I’m new here, don’t mean to critique, I’m assuming you want some answers, just thought I’d lay down some feedback… gettin ready to try the T-5 thing myself, I hear there are better flourescents out there? Happy New Year!

  13. TheBushDoctors says:

    @ArizonaMMJ I am moving away from HPS and eventually T5 as well to switch to LED.

  14. bt4b4 says:

    Under fed….. Your watering too much.. The plants r talking to u,. They r yellow man, wake up.

  15. TheBushDoctors says:

    @bt4b4 I think perhaps we have been taken too long on weening them up on the feedings. I think we need to step up to higher ratio earlier in flowering then we have been.  Only good thing is on this grow it didn’t start to yellow out until it was just about flush time so won’t effect the quality but I don’t think we’ll be yielding quite as well as normal due to running the feedings lighter. If feeding heavier doesn’t solve it next time we’ll have to look at more additives or a different lineup.

  16. ArizonaMMJ says:

    View my videos to get an idea of what you can expect running a total of 500 watt flowering models over 3 plants. We raised the lights for the video. You actually need to keep them super close.

    As for better Spectrum on the T5 bulbs. No one knows what spectrum the Quantum bloom bulbs are. They never shared it. I would however recommend building your own PAR spectrum by mixing bulbs like an Actinic, Coral Wave, Red Sun and a 72.25 this will build a great spectrum.

    Google “led without led”

  17. bt4b4 says:

    U feed, water, water ? Because u don’t want to over feed ? BUT LOOK, u have yellowing. Now increase the N and cal mag. Prob solved. Happy new year.

  18. TheBushDoctors says:

    @LEITHWALKNINJA I would give them a try. I can’t say they increase yield dramatically but slightly but the overall health and structure of the plant is much better for me compared to standard pots that tend to get root-bound a lot easier than air-pots.

  19. bt4b4 says:

    No no no…not over watering like that. Just saying , feed ,water water, is to much I think. Love ur videos man, just hate to see yellowing. I just thought maybe go feed, water, feed may help…..just my thoughts, good luck man. No disrespect brother !


    @TheBushDoctors i may try them in the near future

  21. TheBushDoctors says:

    @bt4b4 The only two plants that are underfed are the ones which leaves you see shooting towards the light.This is not an over-watering problem, I thank you for the input but the symptoms are nothing similar to over watering.And that would mean we would be having water run off and poor absorption but our plants are eating great,just the health of the older leaves is slipping. We either need to run a stronger mix or start foliar feeding I believe because all symptoms are deficiency related.

  22. italianbc says:

    Looking Great

  23. TheBushDoctors says:

    @ArizonaMMJ I agree there is much work to be done with them but for veg purposes there is nothing greater and I believe the same can be achieved in flowering. The thing about flowering with LED’s is the spectrum and bulb angles. I have been following a company that produces full spectrum white LED’s and the veg results are there, I’m just waiting to see flowering results.

  24. TheBushDoctors says:

    @ArizonaMMJ Thanks for this info. I’m going to look into it.  As of right now if I do go LED I’m still going to need a few HPS for supplemental flowering light but I really like these white LEDS because you can see your plants good and your room doesn’t look a off color, just like normal light.But for now I’m thinking of sticking T5’s out another year or so to see what happens in the LED industry and trying my own spectrum like that may increase yield.I don’t think I can increase speed anymore.

  25. TheBushDoctors says:

    @bt4b4 Thanks for the input. No disrespect taken, just trying to explain things ya know. I have thought about feeding on that cycle but I don’t think it would be a smart move being that this is a synthetic line and they recommend feed, water, water especially with soil-less mix. I could easily overnute, lock out or shock my plants by increasing feedings like that.We have only been running 50% strength so we are going to step up to 75% or 100% and see if that helps.


    plants look really happy!! nice clean set up you got mate,do you think the air pots make a difference with the yeild? was thinking of trying them out?

  27. TheBushDoctors says:

    @bt4b4 It is confusing though because we don’t seem to have this problem with any photoperiod strains we grow just the autoflowers so we have got to be underfeeding or the autoflowers can’t handle the mix we run.

  28. TheBushDoctors says:

    @Rapnzapper Yeah a couple need some but most of them seem to be having problems on the P-K side more than the N side but I think we are seeing slight deficiencies all across the board.

  29. isofaster says:

    looking nice for day 55 =)

  30. ArizonaMMJ says:

    Bush- forget LED. It’s not there yet we bought into it too and were very disappointed actually.


    could it be a calcium deficency? just with the rust spots you mention?? are your leaves turning darker green? all the best for 2012 bud

  32. TheBushDoctors says:

    @2dogarage Happy New Year to you as well! I prefer Quantum’s but there are higher powered T5’s. A google search for VHO T5’s should find them for you. I appreciate the feedback. We feed, water, water, feed, water, water, etc so there is no overfeeding going on. I think we are seeing deficiencies across the board. Different strains are showing different signs, some appear to need nitrogen while others need calcium. Really need to get back into monocropping to avoid these problems.
