First grow help needed... pics uploaded

Started 12/12 on the 11th July...
I started having problems that looked that the following pics, I didn't experience those issues when on veg.
I started flower stage with temp 73-77 and humidity between 53%-55%







I gave my plants a good trim on Saturday, they looked weak but recovered the next day.

This is how they looked after trimming





Sunday they seemed much better and fully recovered, however on Monday I experienced a serious problem and light went off most of the day which effected the light cycle, and they had 9 hours of light instead of 12. Today I had to relocate them and move the entire tent to a new place which I believe messed up the plants rotien totally. The where exposed to higher than their normal temperatures and humidity, max readings show
86 temp and humidity was 82%.

After relocating them I watered using NPK 20:20:20 and Calcium, and this is how they look today.

I've been using PHed water always between 6-7.

They need water when they drop like that it's underwater give every second day

Do you have a source of magnesium in your soil?

I don't think so, and the fertilizer I use lacks magnesium, I just received a pack of trace elements that has a good % of magnesium but I'll wait for next feeding before I use it since I watered them just 24 hours ago... or do you think I should use it immediately?

I'd do a foliar spray of magnesium asap. 1/2 teaspoon of epsom salts to 1 gallon of water.

I'll do that as soon as I put lights on and post pics after a day, I have always given them nutes with water and never foliar, i always feared having the plants wet when putting the lights on, I feel that can burn the leafs.

You won't burn leaves from spraying unless you are using oil based products. But good to do with lights raised or cool so you don't spray your bulb.

I'd just foliar spray the Epsom salt only. No other nutes.

As a matter of fact I feel like hanging myself, now that you mentioned oil based products might burn leafs, I used neem oil diluted in water and sprayed the plants. :facealm:

That's usually just fine. You just don't want to apply it too frequently or mix it up heavier than recommended.

I hate Dxing online: but ill throw my thoughts in: light is too far, overwatering causing soil to become unbreathable, inability to up-take-nuets.

its just guessing lol
