Looks like not enough nutrients. What and how much are you feeding them? Ph?

I’d star raising the ppms like 10% a day till they’re looking good.

Looks like an overall deficiency, not just cal mag. You should see improvement in a day or two.

It was root slime. Nothing helped, not H202 not calcium hypochlore, nothing. 2 months fight lost... First time see such a POWERFULL root slime bacteria.. I submerget roots in 6% h202 on 24h and wash all system with chlorine. Pots, tubes ALL. But still she gets back after 1 week..... I dont know why, but nowaday those root rot slimes ar MUCH powerfull .... strange. And Im not alone who told this... Ps. Water temp 17c with chiller....

It's PH. Make sure you're ph is rising. Start at 5.5, it should go to 5.8 in a day, or 2. Water temp 68! Very important. Feed no higher than 350 bpm. If using tap, make sure it's under 220, and subtract 120 from that (an example) Always check for Aphids! Always
