I recently ran into the problems in the video.The new development of the upper leafs are good.However,the under loooks real droppy and dying.Growing in coco+perlite (70/30) feed irrigation everyday PH:5.8-6 , EC:1.8, Run-off 13-15%.
I grow in coco/perlite as well. All it is,is lower leaves are not getting light. So they are dying off. Actually it is probably a good time to start cleaning out lower grow points. The underside to help reduce airy buds. Nice looking bush you got going. I got a few myself. My runtz right now is about 3ft by 3 ft across on diameter right now. 🤜🤛 little trimming, and your will be good👍🌱
I think might be time for me to defoliate these plants I thought it was root rot or something as well my room is contaminated with insects Fungus Gnats.
They look lusty, bottom leafs catch no light so more prone to die with too much water for instance...
Although they are lusty and beautiful i think with coco you should be running much higher EC, but never tried it myself...
Best of luck!
