Ok, so heres the run down...some unknown high quality seeds were planted in a DWC set-up in a closet grow box. They are around 3 or 4 weeks old now and in the last week they started showing signs of necrosis. I have included pictures of the leaves, plants, and the rockwool. I believe I may have a mold problem because this white shit that looks like mold popped up on all the tops of the rockwool, but not on the plant. Please help diagnose this problem so that I can try and save them!!!


The PH is between 5.8-6.2

nutrients are botanicare cns17 for hydro

18/6 veg light cycle.

I use purified water (reverse osmosis)

well man it might be mold get a good mold killer and cover your rock wool from light what is the hum % 60 and 70 works good less or more and fungus grows or pests also could be nutes burn back off for a few see if the new growth gets better and old growth stops geting worse you can see it might be nute burn from the way the tips whent first then also they kinda have a claw look to the leaves if you back off and shit gets back to normal and new growth dont look bad it was nutes if not im not sure gl

Hydroton is more appropriate for dwc. Rockwool needs to drain out its excess water. In a dwc it never gets this chance. See if you can remove any of the rockwool and replace with hydroton or some other very fast-draining medium. You can probably get a good chunk of it out of there without hurting the roots if you are careful.
