First post here Been having some problems here and after reading through some of the books i have on plants, ive decided to come see if anyone here had any ideas to help me out. Light 400w Soil: ff ocean forest strain: ww bid bud Distance from light- around 12 inches but never had a problem previously watering frequency- usually every few days/ when top few inches of soil appears dry with distilled water or tap water that has sat for a few days in 5 gallon containers. Nutrients- general hydroponics floragro, micro, and bloom. Ph meter broke during veg but have only given up to 1/2 strength alternating with pure water. Temp- consistent 78-83 degrees during the night. 60-62 at night. Humidity- usually around 25-30% No bugs that i have seen yet, other plants next to it are showing very very little yellowing compared to this plant. Plant has been in the same planter for a while and its possible its needing trasplanted, but i hear thats stressful to do once flowering has started, is a week and a half too late or will it be worth it in the long run I have three plants growing right now and havent had any problems up until now, The plant is about a week and a half into flower and has started to yellow with some brown spots on a few of the leaves. Yellowing started towards the middle and top. The bottom actually still has a decent amount of green left but i can tell its starting to lighten up. Flushed the plants with distilled water to see if that would help at all, I assume its a type of deficiency as i have no ph meter right now I couldnt be too sure. buying ph test strips today. All help appreciated, thanks
