Nute or light burn?!?! Getting worse!

I have what I guess is nute burn. I have one bubbleicious fem, and one AK48 fem -- 3 weeks old. The lower leaves outer edges are dying and it's getting worse. Everything is getting plenty of light. I am LST'ing as well. The lights are LED. It's in BioBizz light mix. So far all I've feed them is 1ml of biogrow and 2ml of bioheaven. The temps are about 80F and humidity is 50%. The first pic is the bubbleicious and the second is the AK48.

Looks like it got too hot at one point...this can show up days later and then finally turn the wilted parts to a crisp. Pic of the whole plant would help

hmm really?...but he uses a led and its at the bottom ...and as leds use more calcium and magnesium than hps and he hasn't added any extra I thought it would be that

Also, this is a stealth grow using 3 LED light rails -- 15 watts each. They are about 4 inches or so away from the top of the plants. I figured that they could be getting too much light, but the lights are not all that powerful. They don't put off much heat at all. And there's real good airflow.

Yoo still healthy plants besides the small nute burn. Just veg the damage out and I'll be good. I find that a small LED was not enough for my plant. I veg my mothers in a small cabinet under 1 15W Led spot light. Tightwst intermodal distance but it wasn't getting any bigger in terms of diameter. I ended up putting her under 2 t5s with led supplementing the sides. She looks pretty big now. I guess what I am trying to say is that depending on the wattage of your LED you may need a bigger light or more lights. Especially when you wanna flower that delicious AK 48

The new growth looks good, just keep doing what your doing. No nutes yet tho unless you see yellowing

So you think it's just nute burn? Should I flush or trim any of the really bad leaves off? Also, I'm planning on switching to flowering next weekend, around the 23rd. That puts the girls right at 4 weeks for veg. Should I just wait til then to start any nutes?

I am a strong proponent against flushing with pure water. I always use 1/2 strength solution to flush. So mix a batch if veg nutes @ half strength and rinse your container out. Give your girls a week or two before flowering because you don't want to 12/12 with stress. I'd leave the leaves alone unless they are more than 50% damaged. Good luck!

honestly it looks to me like those leaves hung down into the water when u fed and just got drowned a little. Foliar feed some cal//mg just in case.

I have been thinking about that too. I did see some higher leaves that wouldn't have been in the water too though.

give them some cal/mg or epson salts foliar feeding is a great way if they don't need water. Just thoroughly spray em with a mix, if u use calmg+, use like 4ml/gal.

Well it doesn't look like they have gotten much worse. I gave a light mid wee watering, 400ml each. The tops look nice a green and the bad leaves haven't gotten much worse. I did not some brown tips on one of the tops. Here's some pics. First 2 are of Bubbleicious and the third one is AK48.

Sweet dude if it's not getting worse it means it's working. Just feed them at half strength and slowly being up the nutrient to full strength. Glad to see them get better :)
