Getting a few lighter patches on some of the leaves (in the last 2 shots) and not sure what is causing that... possibly the cold? Any help would be much appreciated!

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Calcium deficiency?
So, 2 out of 6 are showing this, it looks like a nutrient deficiency, Calcium I'd say. It's only present in one leaf on each plant, in the bottom. I've got here CalMag ready to apply, just wondering if you guys agree with me :D Thank you, and keep it green :D

Bugs, spiders or fungus?
Hi everyone, what should i do with this in floration? Neem oil? Soap? Im starting the 9 week and i think that if i use neem oil now, it will leave some taste on the buds. I touched some leaves and the white marks stay, it isn't powder, but is white. Thank you 💚

Which volume of soil/Sq metter do you recommend for the best production ratio? I mean number of pots and his volume. I am using 4 led tubes of 20 watts and 6500k is it the best way to germinate and grow the plants for 15 days?

Started to get some yellow spots on the leaves, I think it is early Leaf Septoria. Any good recommendations for maintenance moving forward? How to remove and prevent from happening in the future?

Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?

Deficiency?
I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

Yellow Leaves Autoflower
Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.

Small brownish spots forming on lower leaves. Need help with diagnoses!
Hi all. Just migrated plants to new tent/fan. I have much better environmental conditions. Now I have these leaf spots. I've included recent measurements. I was going light on the CaliMagic using 1/2 tsp per gallon. Is that my issue? Roots look good. Thanks everyone!

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.
