Transplanted into some cloth and some plastic black pots, gave vitamin B before transplant to help with transplant shock. Going from peat base to coco coir. Runoff EC is same as input EC so hope this continues. June 1st they all got topped. Following VPD for vegetative growth. Should prune leaves and branches. Sprayed with 2 parts kelp 5 parts fulvic.
Looks like issues in the root zone. Test your runoff. I would bet the ph is in the 4.5-5 range. This will affect the uptake of nutrients the plants need in flower.
Thanks Kush-queen, DoctorGreenThumb, and StaresAtPlants for your answers. Seems like the leaves come from both top and middle of plant. Run off is 5.4, 5.5, & 5.7 for the different trays. PH going in is 6.0. Plants get watered with RO water every night, I run 6.0 PH, temp 23 EC between 05 - 1 or 500 - 1000. Get plenty of runoff.
