It looks like N deficiency or the pH could be off. The aerogarden nutes are not very good to grow marijuana. I have 2 AG Deluxe PRO 200's and i don't use the nutes that came with it. I use the full line of FoxFarm nutes with Liquid Carma and SubCulture and all of my plants do very well. I also check the pH everyday. I start the pH at 5.5 and then work up to 5.8 as i increase the strength of the nutes. I only use my AG for starting and vegging seedlings, clones and mothers. After that i transfer mine into a 2x2 flood and drain tray under a 400w HPS for flowering. Now that i have seen the other pics it does look like root rot. To kill the root rot flush with some Hydrogen Peroxide (H2O2) with pH adjusted distilled water that should clear it up. Add about 1 ml of H202 per gallon of distilled water. It wouldn't hurt to add a air pump and air stone to the rez to add oxygen to the nutes and roots to help kill and prevent the rot from coming back. You can buy pH up, down and ph testers at any pet store in the fish department if you do not have a hydro store near you. As far as killing fungus and mildew and bugs on leaves you can buy some neem oil at any garden center.Um experts please help i dont think its nut burn and certianly not from the aerogarden lights. Its about what 5,6 weeks in and ims till on default settings. Things appear to be okay except for a couple leafs have some small holes and that dryness they cruble if i touch with my hand. I hope the pictures help... I dont really expect to much this is really a test run before i use some seeds ill prolly get from an advertizer on this site...
Mix 1-2 cap fulls of H2O2 to 1 gallon of distilled water with a pH of 5.8. Flush with this solution for a day. Then mix fresh nutes with the SubCulture and change the rez. Do not mix the H202 with the SubCulture because it will kill the good microbials.For washing the roots with peroxide.. (i got 3%) how much do i mix that with water or should i just take the roots and try and rinse it in the 3% solution..
