Dropping plants! I have happy plants and sad ones

Been having an issue with droopy leaves for about 3 weeks now , it’s not on all my plants just certain ones specifically my train wreck and it’s very on and off yet they are on same watering and feeding schedule.This is my first indoor grow second general grow, I water by weight of soil ,I even have a 3.5 gallon bucket that stays dry so I can compare , after adjusting my watering I started to see change on all my plants expect for my train wreck she never seems to fully perk up.
My grow set up:
1,000 watt mh large og air cooled hood
5x5 tent 3.5 gallon pots 20/4 temps 68-86
fox farm Ocean forest soil
Tap water 6.5 ph 380 Ppm
Compost tea / fish em,liquid kelp ,worm casting , molasses , bu blend compost brew for 36h only feed twice so far.
The pictures attached are taken 01/02/2020 they were fees and watered yesterday I also trimmed large fan leaves from all plants
Any advice is appreciated I just wanna figure out what my underlying issue I feel like it stunting my growth as well I put them under 1,000 watt on December 1st . In the picture you will notice some healthy one and some droopy ones this is my main concern

Train wreck

My WW looked like that and gave em a nice watering and they came back the next day. Droopy leaves can actually be not enough water or too much water.

They look a lot better . Still have some not thriving as others, I repotted to slight bigger pot with some Fresh soil,also purchased some terp tea bloom See if that helps as well

Root bound...prolly gonna have issues if u dont stay on top of things or transplant

Looking better , also top dressed with compost ocean forest and teaspoon of terp tea

You need a good wet and dry cycle. You are either over watering or under watering....

Sometimes mine do that around 6 to seven weeks in veg or the first couple weeks of flower..., most the time it’s cause they grew faster than the roots did ,they get over ambitious, can’t support there own growth. you should reall chop em up the earlier the better helps the roots get ahead .... it’s hard to chop them up when they are so pretty but trust me it will save you major headaches in the future.. most the time once they veged a while they perk back up no sweat .
Edit : on further inspection your flowering already think you it’s needed more veg time ..... sometimes it happens for a week than bam right back to normal!

I am giving them one more week then flipping , running out of space , and I have a massive 1,000 watt air cooled hood

Get a soil meter. They're cheap and guesswork is stressful. Indulge yourself.

Watering now lasting my 3 days after going 12/12 plants are happy all the time , getting their dark green color back , feeding compost teas every week now.
