Hey.
Thanks for the ideas, yeah originally like 2 weeks ago they were too close to my HPS, so I put them under a fluro for a week, now they are under a HPS but they are about 1.5m away (roughly around 5 feet) from the light.
I think it could be the soil, but the thing is one from each strain is doing amazing, where as the rest are not doing so well, thats why I'm confused, if they were all good / bad I'd understand, just some are doing better than others, I suppose it's all genetic.
I just moved the good ones into a better soil base that I have used before and am planning to transplant the rest within the week.
Also from the move I just done, the really good ones have a much further advanced rooting structure than the ones that I have now thrown away (not pictured but they were completely fucked)
