Canadamade420answered grow question 4 years ago
Hey, you are correct. She is getting too much heat and the water can’t get to the leaves fast enough so they burn up. Maybe try putting an extra fan in to get those temps down a bit. The calmag helps too with the stress the girls are on from the heat. Happy growing
The8thChevronanswered grow question 4 years ago
Definitely a calmag issue but also looks like she's begging for more phosphorus. Whenever I see more than one nutrient issue simultaneously, I always assume you have a pH problem which is limiting the nutes that the plant can take in. It is always possible you just slipped up on multiple nutes when making your feed, but definitely check pH and calibrate your meter before doing anything else. Good luck!

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Curled leaves and brown spotsPlease help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.
