I CANNOT figure out what's wrong with these things. The lowest leaves turn brown and wilt first, while the uppermost leaves have been yellow from day 1. The most recent development is the tips of the biggest leaves browing and either drooping or actually folding up on themselves. They're white widow, so I'd reallllly like to save them, but the only thing that seems to even line up a little is chlorine poising (based on the description from Jorge Cervantes' marijuana Horticulture), and that shouldn't be it because I regularly regulate pH and use reverse osmosis water. Light burn would def not be an issue right now because im just using two little CRLs at the moment, overfertilization shouldnt be it because, well, I'm not fertilizing them yet since they're seedlings. So I would also THINK that a deficiency wouldn't be an issue either... please help? Don't mind the incorrect plant labels. lol

they need food, 1/2 strength for the first couple of weeks, unless your soil already has food in it?

I gave em 1/2 strength food (AeroGrow nutes, but I've seen elsewhere on this forum that those are fine) last week, and thats when the problems started. ALTHOUGH, I did mess up and put KoolBloom in it (1/4 tspn per gal 2-45-28 flowering formula. I was high. lol), which was in for a day or two. Could that be it maybe? The toxicity symptoms for the high phosphate and potassium levels matched less than those for the 2% nitrogen, so i dunno....

what you can do is completely flush your pots and see if that helps

looks to me like nute burn u prolly gave them to much nutes when u gave it to em and they were prolly to young to handle it

or... your soil has nutes in it and u over watered once or twice which realeases those nutes causing i to burn your plant and the over watering would give it the yellowing

what kind of soil are they in cause that does look like nute burn, time release foods suck.

flush flush flush that should solve your problem. and make sure your soil doesn't have any nutes in it, if it does just add plain water until she gets alittle bigger.

No soil, just weird spongy stuff (Whatever Aerogrow came with). And I've been running it with nothing but water since I noticed probs (around thurs-fri last week), but they're getting progressively worse. I'm THINKING that I could have over fertilized and then not given them any nutes, so it could have been like a toxicity/deficiency double-whammy maybe? I dunno. I just added a half dose of just the AG nutes, so I'll see where that takes it. I do think I need to invest in better nutes soon, but my budget is exhausted for the moment.

ALRIGHT! Problem solved! I added a half dose of the AG nutrients and it brought them right back (now I have new and improved General Hydro nutes ). Therefore, I guess what happened is the blooming formula I accidentally put in burned them, then when I switched to plain water (reverse osmosis), they were starving. Doy. Thanks for your help guys.
