Langbeinite is an organic amendment that has potassium, magnesium and sulfur. Its a naturally mined crystalline mineral that does not alter the ph.

Reveg/Budding issue
What is my plant doing? the days are almost 15 hours long so I don't understand why it's budding still, I expected it to reveg by now but no sign of rounded single leaves still. The days are getting longer not shorter, end of next month is when the days start getting shorter.

Upside down leaf growth?
What is happening to this plant, it seems to be growing leaves upside down? It had nothing come out for a few days and then 2 new leaves started to grow out of it but it's like the top dark green side of the leaf is growing on the underside. Any ideas on what I should research?

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...?

Light Green Color on Seedling Growth
This question is regarding the photo of the seedlings below. One of my seedlings is beginning to turn a bright green color in the center near the new growth.The other is staying a dark green and I am wondering what could cause this as they are both being cared for evenly.

My Tangie photoperiods small leaves are curling upwards around the edges. Anybody have a reason for this? It's the only one of the 4 exhibiting symptoms like this and only one of my autos of the 8 did the same thing. Is it too much or too little water? Not enough airflow?

Should I defoliate light-blocking leaves from my NL auto?
My NL auto is at D40 and is growing well. She's developing a good lot of cola's with nice bud sites. Up untill now I've been able to tuck the leaves away, but it's getting more difficult to keep all bud sites cleared as she keeps growing. Should I tactically defoliate?

Crispy leaves?
Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.
