I got some new pics today The plants are now 32 days old and I'm pretty sure that they have recovered from whatever the illness was... the new growth looks awesome and I got rid of the affected leaves. Right now the pH is 5.57, ec 912, ppm 457, and res. temp is 70.9F. Room temp is 77F and humidity is 42%. I tried foliar feeding them and I think it has helped some... ive also been able to convert the system into an ebb and flow by putting coins over the drainage holes and letting it fill up. I do this about twice a day 6 hours apart along with the regular spray every 3 hours. I was also thinking that I could turn it into a dwc system by raising the drainage pipes height into the system thus allowing it to fill up and then fall back to the reservoir. Then just put some airstones in the four trays I think that could work out. What do you guys think?
