answered grow question 4y ago
can be a cal mag deficiency, but before check your ph (has to be something like 5.8) and the power of your light (too close/ too much power etc)

I think it was a cal mag and everything else too. I believe I was just under feeding them. Thanks for the help

Is she worth it?
What happened to this seedling? It sprouted with 2 cotyledons (looks like a piece is missing from one) but only one true leaf. It also sprouted with the leaves facing straight up but now they are all facing to the side. Is it worth keeping? It is on day 5 since soil germination.

Common theme is a week of sugars and a week of flush. But here's what doesn't get talked about... Do I keep the PPM stable or do I let it rise/fall. If I'm running straight up RO, the water is going to gain more ppm. Does that mean I should change Rez daily? Add sugars daily?

What are these symptoms?
Hello everyone! My plant is currently experiencing a few symptoms that I don't quite understand. Pics 1 and 2 show them the best, with the leaves from pic 3 to 5 having similar, not so heavy symptoms. Pic 6 I believe is something else, Not windburn though, leaf is too far inside

Organic slow-release amendments...How does an excess occur? I thought that couldn't happen :-/
While these gals are super healthy and look great (What do you think?), I'm looking for high-standard criticism/advice. Are these leaves too dark (Slight claw on certain leaves, N excess?)? Also see very minor tip burn. I'm using organic slow-release amendments...?

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)
