First grow, this morning these three plants were fine. ppm- 250 ph- 5.7 1 1/2 week old. Any help would be great; the worst one was completely fine this morning. I checked on her this afternoon and her leaves were turning brown; it seems to be getting worse pretty rapidly. I didn't think it was nute burn; i assumed the ppm was in a reasonable range. Anyone got any ideas?

pH should be 6.5 ..... 5.8 is too low. I just had this same issue last week. Dolomite lime would work. I've heard vinegar too.

I thought ph was 5.5-6.5 for hydro

It looks like it's your nutes to me. I don't know the first thing about hydro though. Just come back in 30 minutes and if there's no reply then bump your thread.

I looked over that earlier and honestly can't tell. Posting is more of a last resort.

According to that it looks like magnesium or calcium. wouldn't hurt to give those two a small boost and see

Im afraid to burn them but it does look like that doesn't it? i honestly wanted someone just to go NOPE NOT NUTE BURN so i could go ahead and feed a little more.

What you got there is a nute toxicity problem . Too much on the micro nutes , your plants are too young to be showing signs of under fertilizing. You have a toxic mixture of something. Did you check the ppm of your water before you added nutes? Did you check the PH after you added your nutes ?

It's ro water, it started with 10 ppm, i raised it to 150 ppm with a few drops of nutes, ph is 5.7 as i stated before. with a little bit of h202, that was yesterday though,today the ppm is 250ish and the ph is still at 5.7
