Coco/Perlite Plants Not Growing

I'm having some very serious issues with transitioning to Coco/Perlite.

I have set a drip system with a reservoir and I use Dutch Pro nutrients and try to his 800-1000 PPM w/hard water.

I try to water once a day, sometimes every two days and adjust the pH every time. I leave the nutrients until all the water is gone and I have to refill it.

Some plants have run-off trays and some don't. Doesn't seem to make a difference, as the water just stays inside the pots like soil. I can't tell why.

Lights are 600w at proper distance.

Temperature is kept at ~28C with good air-circulation.

The plants don't seem to die quite as easily and they NEVER wilt like they did in soil, but they just won't grow.

I have several clones that are simply dying. I'm not sure if I'm watering them too much or too little but they shouldn't be dying - I know that for sure.

If anyone could help, I would really appreciate it.

I'm considering uprooting all the plants and putting them back into soil where it's safe.

Thanks.

Tell me about your nutes. Do they contain trace mins and Ca and Mg? Did you flush the coco before using? They look like they are seriously deficient in Mg and maybe trace mins also.

You're not getting any runoff? What % perlite?-granger

Don't know the percentage. Got what everyone around here uses.

Dutch Pro nutes. Worked just fine in soil.

I watered them yesterday until there was run-off. They look even worse today.
