Taco leaves curling down

pic 1, bottom left, is that human damage on that fan leaf or bugs?

Ahh, that happened during the LST

have you checked for mites on the under side of the leaves? you'll need a scope to see them, not with the naked eye.

You sure your air stones are blowing air?

I checked a few days ago with the magnifier and I didn't see anything, I can check again later

Yes, I've been checking this every day.

I just took a photo now, the photos I added 2 days ago where from the plant with the blue arrow, it's like 70% recovered. The other one it's pretty much the same, maybe a bit better

the one on the left has alot more tip burn. and some weird spotting on the leaves too down by where you can see that black lid.

is the one on the left eating? drinking? how old is that tip burn? old or new?

There are 4 plants there (it's hard to tell from the photo, sorry I didn't mentioned before). The one in the top left is the one having the problem, not sure if you are talking about the left at the bottom (I had some calcium deficiency a month ago due to low PH because the pen wasn't calibrated, she is fine now). They are in the same reserve of water, so it's hard to tell witch one is drinking more, the TDS value drops a bit every couple of days so I don't think I am over feeding (in general, could be that one plant drinks/eats more than other, I never go over 900ppm). It happened only to the 2 tallest plants

can you isolate the bad plant in it's own bucket if you have the room? if so, i would flush it with plain water for 12 hours minimum and start back on lighter nutes with her. that plant might not be eating or drinking at all.

Sometimes the nutes recommended are too high for dwc, since the roots are in full contact with the nutes 24/7. Probably a longshot, but it might help. Peace, and best wishes.

I don't have much space, I will wait a couple of days to see what happens

Yes, they are, if I follow the recommended dose it will get at 1600ppm. The sweet spot I found is around half dose between 650 and 900 on flowering

Thank you everyone for your help I really appreciate it. I will wait a few days with the adjustments I made to see what happens

Thanks for your numbers. Every bit helps as we forge ahead.

Please let me know how things turn out. I always appreciate science and real data, not to mention great results. And just curious, but do you have space between the bottom of your net pots adn the water line? Also curious what your ppm is for early veg and veg...just what you've had good results with. Best always.
