I need help! These plants are 2 weeks into veg... I've been growing for years and have never had this. This is a NEW barn, new paint, new everything.
The leaves are curling down and have crisp edges. Copper spots and the newest growth seems the worst with the curling down of the leaves.

Looks like root disease to me... pythium? I recommend a good powder microbial soil inoculate that is high in trichoderma in particular. Also maybe some Kelp and Humic Acid

Also Yucca in your foliar spray is always good...

Yucca extracts are taking the place of copper sulfate in much of Europe to help prevent and treat fungal diseases such as apple scab.

Thank you! I didn't think of that. I took one out of the pot to check roots, they looked pretty good, nice and white. I still listened to you and blasted them with great white! I'll try anything at this point.

I wonder if the new wood or fresh paint have anything to do with it? The paints dry but I can still smell it. There's a million things it could be!

I hope the Great White fixes it!

Really appreciate the advice! Thanks so much for your time.

How are you growing?
Whats the media and have you changed it from something else?
What water? RO, Rain or something else?

Looks like Ca mostly....Kinda looks like a pH problem is in there along with other tings adding up....

What do you feed and how much, how often?

I've been doing this for years....I have 2 rooms going and I did everything the same. Same plants same water, same everything! The other rooms blowing up with no problems. The only things that I can think of that are different are.....
1) Didn't use Great White on this one, bought a different soil with microbes!
(I added Great White yesterday)
2) New bulbs
3) new reservoir (BIG olive container cleaned it twice really good).
3) sealed the wood with water based paint (smells strong)
4) used tables to raise plants made with plywood (not sealed). Took out ALL tables yesterday! Who knows if theses a formaldehyde in the wood.

Those are the only differences I can think of!
