Well, it's not over yet, I just tested the ph of the soil in one of the containers and it looked like it came in at 6.5...the affected plants are growing great new growth, but some of the existing growth is still browning. The tips on some of the new leaves are browning too, and now I'm starting to freak. Maybe it is still a serious nute deficiency, as I only fed 2tsp of big bloom per gal and 2T of grow big per gal at feeding time, which was 2 days ago. I used my moisture tester, but it gives different readings for different containers, ranging from 4-7 (10 being most moist) based on no real pattern...

I guess I'm going to let them dry out another day and see what happens to them. I'll check on them again before bed to make sure they're not drying out...

I'll keep the perlite layer in mind for the next grow, I should have done that this time, as I've done it before in other container grows...of other flowering plants...
herbaltivo Reviewed by herbaltivo on . yellowing tips, brown spots, Ca deficiency? Hi, first time grower, 6 plants, bagseeds, day 23 of veg. 2 of the plants have nasty looking yellow tips on the lower leaves. Pictures say more than words. I water, but have not as of yet fertilized. I just got my fox farms products today and will be using them tomorrow. Soil is too wet to water today. 2 175w MH, 6 or so 100w cfl's for lighting. Temp is always around 78-80. Low humidity <20%. Was thinking about putting a pot of water in there to evaporate off some moisture. Three of Rating: 5
