White Widow & Dream Queen Glue

D24 -This summer is making it very hard to DWC because temperatures it's causing root rot and brown stuff, it's Clearly an Oxygen issue on rootzone, but plants still haven't show any sign of weakiness (maybe growing slower than they should only..) Rez temperatures around 27-28C (81F !!) ( and growroom 31C, this is causing roots issues because low DO, today I'm upgrading rez air pump from 1.5L/m to 4.5L/m by adding another oxygen pump and another air stone to them. It's impossible to me to go for a water chiller atm , maybe after I upgrade into a RDWC in the future, but for now I'll have to deal with the temperatures. Also doing an experiment, on DQG I started to bleach the fucking out of it with 50% H2o2 peroxide in attempt to kill all microorganisms and to increase DO since H2o2 will turn into Oxygen, will dose 2.5ML/gal daily and also stoping using Great White there since H2o2 will also kill the good guys, on WW rez will keep Great White and no H2o2. I'm checking after a week or so wich one is doing better. Increased light to 75% - 450W Increased nutes to 70% recommended by GH. DQG - two main branches growing, will let'em grow a bit more before topping again WW - managed to keep 4 "mains" amost same size / height, will let them grow a bit and top again for 8. ------- D26 - Both roots seems to be more "hairy" with new oxygen pump, WW still very brown but DQG seems to be recovering. also both are very small height, I think may be due too much light, next grow I'm starting with low light so they can stretch a bit more and have bit more spaces between leaves. WW - topped biggest node, currently with 5 main growing tips DQG - removed 2 lower growing tips in attempt to make upper ones grow faster, maybe more 3 days to seccond topping
