More info would help:

Type of water?
What exactly are you putting in the rez and the EC and pH?
Temp and humidity of environment?
Light and hanging height, dim setting?

Sink water left out fir 24hrs. Then I do the nutrients and the ppm test at 650 and ph at between 5.7 and 5.9. My temperature has been 68-73 degrees on hot days. Humidity doesn’t go lower then 60% and usual rest at 63%. I use the mars hydro 450w dimmable 2022 light with it at 60% power. I have it hung 16 inches above the plants. I also use great white and hydraguard for bennys. Using general hydroponics 3 step with the recommendation for veg.

It looks like a little bit of light burn from when it was younger. I'd keep watching it and see where it goes.

This is mine now, 2 weeks.

I had ppm at 650 and it did not like it at all, started drooping down.

Diluted the solution to bring ppm down to 400 this is how they look like now. Mars hydro 300w at 25%

They did not like it at 50%.
So dim the lights and less nutes.

Best tip I can give you is use smaller net pots. 6 inch are great. Way less hydroton needed and plants are more stable and less likely to tip.

What is the starting PPM of your tap? I use RO with GH nutes and your feed is what I use in flower. How many ml/gal of each part are you using?

As mentioned, that light is way too bright. Look at the PAR charts that came with the light and dim it down to the appropriate levels for the hanging height. You want your PPFD to be between 280-550 in veg.

Yes. Thats what i use.

Starting ppm of my tap water is 150ppm.

Hydroguard, cal mag, general hydroponics quarter of whats specified and pm down to bring pm to 5.8.

It seems to like this combination.
