ok heres whats up... DWC is my game im a specialist cuz its my main grow mode. you put 3 plants in too tight of quarters. plants can sense overcrowding and it causes shock. your rootmass cant properly uptake. i use the RF66. http://generalhydroponics.com/site/index.php/products/systems/rainforest_series/ and yes i know its an aeroponic unit but i dont use the vortex sprayer. i just DWC with that unit.
and i put 3 plants per 15gal unit with 4 airstones fed from a 110L commercial pump. and on occasion i get root shock. I also use the 5gal buckets simetimes like you do but only with 1 plant. and those can cause root shock if the roots fill it out too much.
your suffering from N and K mainly. Heat stress is very probable.
USE LESS PLANTS OR UPGRADE YOUR DWC UNIT good luck homie
