Curled leaves and brown spots
Please 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.

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. Started around 6th week

Stickstoffüberschuss?
Habe bei meiner Auto das Problem das sie kaum in die Höhe wächst, dazu die Flecken auf einem Blatt. Ich habe aber das Gefühl das die anderen Blätter auch zu dunkel sind? Vielleicht wächst sie wegen einem Stickstoffüberschuss nicht mehr?Sollte ich erstmal ohne Dünger gießen?

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.

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )
First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared. Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

Brown Spots on Leaves
I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?
Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance. Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?
