Outdoor concerns

Hi, here I'll post some concerns about my first time outdoor grow. I'm using this plants as a experiment to see what I need to improve next time. I'm hoping you can give me a hand with the problems so I can make it better next time.

I live in central america (spanish speaker), so right now we're in raining season and its so humid that many of the problems are attached to this condition. As you can see in the images, the stem is very tall I think its due to the clouds that are very often shading the plants, so they tend to grow this tall. Already thinking in topping eariler next grow.

Set up: 1mx1m greenhouse with some extra led lights to get 18 hours of light a day for vegetative stage.
These extra lights attract way toooo many insects at the night and thats why the leaves have bites in some pictures, I tried some garlic with soap and olive oil but didnt work as I need it.

Concerns:
1) Insects as mentioned above.

2) Fungus(pictures 1st, 2nd): I had like a wave of fungus in my leaves so I made some Lactobacillus to control them, but I think I used it too often and the leaves were like wrinkle so i needed to get rid of them since they were too bad and just using energy (I guess). In the pics you can see the white spots all over the leave's surface.

I moved on after I pruned my plants, topped them and applied some LST. They were going good 'til this:

3) Overfertilization (pictures 3rd, 4th):This time i think its an over fertilization, it happened to one of the younger plants and almost to an older plant. Maybe I used the fertilizer too often and it was too much for the younger plant. The leaves just dried and died, starting from the inside of the leave to the outside, with a brown color.

What should I do in these two scenarios?

PD: I think I should move onto a bigger greenhouse with better growing conditions to avoid fungus and insects, what do you think?

The fungus is powdery mildew. I'm not sure what you have access to in your country, but Spraying with milk is a common home remedy many gardeners use. Otherwise, an oil based product like neem oil or stylet oil provides good control for PM. You may need to get a fan or find a way to increase air movement in your greenhouse and that should help control the PM.

Your plants do look like they are not receiving enough sunlight, which is why your stems are stretching so much.

Agreed looks like PM and I would say fungas gnats could also be affecting your plants but the brown could be from a variety of reasons so hard to say from couple leaf pics. Are you letting the soil dry out whenever possible?

Hi, according to the photos in internet it seems correct. The lactobacillus is stored in milk, then I guess it should work as well. Actually I did messed up the leaves after I applied lactobacillus but the fungus didnt return.

And yeah, Im going to buy a new fan soon then.

Yes, I let it dry considerably before watering it again. They may be too exposed to the wild since I live almost in a jungle. Maybe a better aconditionated greenhouse would solve the problem.

It’s hard to say for sure exactly but a green house will most likely not resolve these issues as PM and fungus gnats etc can still be present in a green house. Also this does not look like an exposure issue to heat or wind to me. It may be a combination of fertilization and ph issues. I would flush the plant with ph 7.0 water 3 times the container volume at least and then slowly start feeding a mild solution with appropriate PH for your growing medium. Do you have a way to measure ph of your water? It’s commonly overlooked and usually the cause of plant deficiencies.
