Dawn soap and water, blast the underneath of leaves twice a week for 2 weeks when the sun goes down. Bugs will be gone right away but you have to also get the hatching eggs

I had 100 ml mixed with 25 ml of rapeseed oil a little sprayed on my hand and the leaves eingeririate with it, supposed to help against spider mites

Hi mate. Once, a little bit of sunflower oil dropped on the leaves of one of my plants and burned them. So try to be carefull with that rapeseed oil.

I dried this plant for 6 days and am currently dry trimming. While trimming I found some seeds 😣😳Over all the buds (and I checked all, believe me 😀) 7 seeds, 1 I squished, they are either white or in their green shell. Why did she herm, what's it mean & what to do with seeds?

Main stem snapped
LST gone wrong. Main stem snapped after the last LST session, must have happened a while after adjusting the ties. Taped the damaged area. Will it recover? How long would it take? It looked like only 25% of the stem was holding it together. The area got red/brownish.

Defficiency or light burn?
I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here? Ive added a tiny dose of calmag, can I supercrop this late into flower?

3 leaf plant. Please help. should I leave old branches and carry on with them or will they affect plant?
Hello looking for some advise here. Due to less than great weather here frost warnings and rain during days the first couple weeks my plants didn’t get full light I believe this is why I have 3 leaf instead of 5. New ones are coming in as 5. What should I do from here?

Plant in late flower accidentally left on 24hr on light cycle after swapping light because if malfunction. Thoughts?
Photo fem plant was accidentally left on 24hrs a day for roughly 1-2 weeks mid flower when swapping lights, switch got flicked on timer. Plant doesn’t seem to show signs of herm, but is definitely concerning. Was curious why it wasn’t bulking up. What damage could this cause?
