Hey everyone, This is my first grow and having next to no experience with growing, I'd hope to get some advice on my current situation from some seasoned growers. My setup is a homemade ebb and flow. I have a 20 gallon reservoir, going to a tray with 11 6" net pots. I'm growing all auto flowering strains. I'm also using a 400w MH light at about 18" away from seedlings. My strains: Auto northern lights Auto Red poison Auto Berry Ryder Auto purple kush The problem I'm having is my plants starting drooping a day ago and now they begun to turn yellow/brown. I germinated the seeds almost 4 weeks ago in rw cubes and definitely feel they've been stunted because of the underlying problem I'm experiencing. I germed them under a cfl on a 24/0 light schedule for the first week then put them in the hydro setup under the hps with a 18/6 lighting schedule. I foolishly added very low strength nutes (general hydroponics brand) to the hydro reservoir, maybe 1/8 strength or so, and don't know if my plants have mute burn or maybe some defeciency. As for temps I'm reaching close to 90 F when the lights been on but now have a fan blowing across light and plants. Temps reach 65 when lights off. I just today refilled the reservoir with new water after cleaning it out. I only put in fresh water phed to a little under 6. I'm hoping this will help the plants since I've read autos do not like nutes until flowering. Any help would be greatly appreciated! And thanks in advance for the help!
