Seedling issue: please help

[TripleCchronic]

Im currently growing two different strains. One is a photo. Kush and cookies CBD. The other is an Autoflower Tangerine Dream. Everything started out perfectly normal and then both seedlings started showing Browning on the tips of their leaves. The Autoflower Tangerine Dream also in addition to the Browning has started curling it's leaves downward. The conditions in my tent were fairly hot at 29 degrees Celsius, but I have since brought the temperature down to 24 degrees Celsius. My relative humidity has been steady at 65% I have not added any nutrients yet. When see if you begin I did however mix a very dilute 11 ratio General Hydroponics Flora Trio. It hasnt seemed to do much if anything. There was some npk microbes added to the rockwool which im not sure it that coukd have caused this?

I think your rockwool might be causing the issue by trapping in too much moister in the cube. On a Dwc system those rock wool cubes soak up the water and stay tamp when your water level is high in the reservoir.

I’m no pro by any means but it looks like nutrient burn to me. Do you have roots out of the net yet? If not, hold off on the gh trio until you do. Also, what is your ph and ppm?

i like to feed seedlings half strength clone solution with about 1ml per gallon of hydroguard until there’s a few inches of roots hanging out of the net. Then its onto the real food

I gave up using rockwool along time ago because of issues like that and moved to Rapid Rooters. They work graet every time. Looks like there is to much water and not enough air in your cube and it is slowly drowning.

Definitely looks like too much water but I’ve never tried growing in whatever it is you’re using, so I don’t know. Have you tried growing in this medium before?

Not to be a dick, but I have a hard time buying that. There may be a bug on there somewhere but that’s not what’s responsible for the plant looking like it’s on chemotherapy. For whatever reason, the roots are drowning.
