Leaves curl on upper new growth and mid but not lower.
Dankbudz84started grow question 4 years ago
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Hi your leaves are like that because of to much Nitrogen at some time during the grow. You have now lowered n and increased p and k so it won't get any worse. Leaves won't recover and will look like that for rest of grow, newer leaves will look a bit better. Shouldn't harm your grow to much as you have spotted and corrected it before it got to bad.

Should I hold the water?The pictures of the two plants are being taken care identically(diff strains). One is looking a little wilted. Neither plant has been watered since Saturday. Or is it perhaps from me excessively tucking the leaves? Fingering the pot is about 4-5inches is dry soil.Leaves. Curl down

One of three plants curled its leaves.One of these three seeds seems to have suffered a bit, but unsure why - the conditions have been pretty much identical from what I can tell. The first set of leaves curled quite significantly but the new growth seems to be ok? Any ideas?Week 2

Brown spots, serrated edges curling up - calcium deficiency?This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up.
Is this just a straight calcium deficiency?Leaves. Curl up

Burn, deficiency or other?I’m completely stumped as to why my one plant is showing signs of deficiency or burn. Used the exact amount of fertilizer per plant. One plant is fine and the other looks terrible. I used a half dose of cal mag and it seems to have stopped but is not drinking or looking better.4 years ago

clawed leaves.. possibly from wind burnI windburned one of plants quite a lot (possibly others too). It seemed to me as stunded. After 7 days and topping some leaves are still clawed down (middle plant on pictures). Typically the big fan leaves. I wonder if there could be other reason for this and if I can do anythingLeaves.
