Hi all, I'm currently growing some white widow from seed, and I'm having some problems. They're 9 weeks from sprout, flowering for 3. I transplanted into 5 gallon buckets of straight FFOF at 2 weeks and put them under a 400w MH to veg for 4 more weeks, giving them only tap water from a res and 1 drop per gallon superthrive.
I fed them Jack's classic nutes at flower, gave them a neem treatment, switched to HPS, (4 weeks after transplant) and towards the end of the first week they began showing nute deficiency. I properly diagnosed nute lock and flushed at the beginning of the second week until runoff ph'd at 6.7-6.8.
I gave the buckets a week to dry out, and I watered them again, runoff was back down to 6.1!?!? ...added lime, flushed them again, runoff 6.8, and still the problem was advancing. I picked up FF tiger bloom and nuted them 1 tsp per gal on tuesday, used ph-up to balance the water at 7.0, and the problem is still getting worse. Today begins week 4 of flower.
I've considered the possibility of mold, but it's affecting one plant very badly from top to bottom, and the other 2 only the bottom fan leaves. My RH is 55%, daytime temps are 75-78f. I lost my first grow to mites, and this is my second attempt. (bleached & wet vac'd my entire basement, fogged it, no-pest strip, neemed everything, installed an a/c, tend in my skivvies, the whole 9... no signs of mites yet but I'm ready if they do show) 1st pic 3 days ago, second pic today. 3rd pic is black shit all over my plant.
