Stickanswered grow question 7y ago Hi there! Hard to say with your last pictures, but my guess is that you overfed your plants with too many nutrients and inappropriate pH, resulting in a nutrients lockout. Your plant is now unable to absorb nutrients (could be Potassium, Magnesium or Iron..) and she responds with those signs, asking for help! As for an example, 3ml/L of BioGrow during week 11 is way too much! BioGrow intakes should have stopped right after the stretch ended. She only needs BioBloom+TopMax+BioHeaven if possible. Also, your babies might suffer from pH fluctuations. Why did you apply a 6.8 pH for this last week? You should stick to a 6.0-6.5 range. Now, as an emergency move, I would flush the soil for a couple of days, with plain pH'd water (~6.3), let the soil dry between each waterings, and see how it goes. I'll be around, keep us up-to-date, and happy growing!
