I think that's the problem. But, is it algae or the roots developing chlorophyll? (I think it's the latter and that's worse?).What I'm hearing in this thread is that "the problem can't be the small white buckets, I don't know WHAT the problems is....but it can't be that." so I'll back out now.
I agree with JimmyI bet your 1000 watt lamp has accelerated their growth and nutritional uptake. Plant metabolism and nutrient use can fast forward in some strains under powerful light. To me they look hungry and their shoes are too small.
I noticed on one of my other plants half was yellow and other half was green all plants closet to light started to have issues and plant furthest was just fine. Plants were one foot away from light. Didn't plan on autoflowers getting so big.^^^^To much heat perhaps but not to much light. Perhaps wasted light if the plants unable to use it but it won't hurt the plant I don't think. The heat will though lol.
I agree, i found this out the hard way about 10 years ago.... they will show different signs of diff deficiencies when they need to be transplanted. They are trying to get your attention! The reason the t-12 didnt do it is d=because the light spectrum is a lot less demanding and doesnt promote abundant root growth the way A hps 1000w would. So just transplant your ladies and watch the transformation... Good luck Grower!BAAHHH...they appear to be root bound. Those pots looked bigger. Root bound plants show all kinds of odd symptoms. Any thoughts anyone else?
