A pk burn if one of the worst things that could happen to this plants. The affected leaves will never recover and continually look worse but the flowers will benefit from the extra dose of nutrients. Just back of on the feed, alot. Keep using plain water maybe do a water, water, feed, schedule at half the amount or less nutes

Browning leaves sections of leaf surface discoloured Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!

Emerging Issues - Week 9 At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Brown Spots on Leaves I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.
