One of my plants haven't recovered. Decrease the light intensity to 200w at 20 inches. Fed calmag today at 4ml per gallon. Top dressing in soil with Dr Earth flower girl and EWC. Did that 2 weeks ago. In soil. At day 60. Mephisto double grape. Ph water to 6.3.

You guys have been so helpful in the past.

Any clue what this could be?

You really don't need to add cal/mag. There is plenty in Dr Earth.

I screwed up a few weeks back. It got better. I know it's deficient because I flushed the hell out of them weeks ago all but one recovered after feeding. I need to find kelp meal locally. I watered today. Would love to add it now.

Yeah, you can't flush the nutes out of organic soil as they need to breakdown before they're available.

Once I realized that was the case I stopped and fed the plants. Knowing it's slow release I figured it would take a little while to recover.

How long does the kelp last?

How much flower girl did you use? I use a mix of 1 part 444 and 2 parts flower girl for flower. 2 tbls per gallon of soil.
I'm thinking burn instead of deficiency. I've found Dr E to be a well-balanced nutrition. And it will burn!

I do the exact same thing. In 3 gallon pots. Burn is bad. Prefer def

Bro my new cuts of Critical Kush are doing the same thing. I think in my case it's a mix of calcium & Potassium deficiency? That's all I can figure.. All the other plants are fine in the same room, same feed and everything.
