My plants arnt looking as healthy as I want. What is the discoloration? using 400w hps and two led lights.

These briefly saw heat over 90 early on. I have it under control now.

For nutes I'm using fox farm grow big right now.

I'm trying to fix issues

try a couple close ups on buddy.kindbot.io
Buddy suggests nitrogen and magnesium based on light green coloration and light yellow striped leaves
a couple leaf close ups might help narrow your search

I don't grow soil but everything I have seen says drainage is very important. Hopefully someone with more experience can say for sure. To me it looks like root issues which is why I asked about drainage and you returned with the reply I was most worried about.

Yeah. I figured. I'll have to get totes so I can water until it drains

You will most likely get more and better help with all the pertaining information.

Soil
Ph
Temp
Hum
Ppm
At the least

If you're using premixed prefertilized soil and adding nutes that would be an issue. There should be a three part system to your nutes as well. You might want to try brewing a heisenberg tea, look it up, to help possible root problems. I'm not sure about soil dosages but easy to find.

That seems like a lot of light? Try downloading a light meter app and test how many lumens your at. Plants don't recognize lumens but its a good way to know if your lights are to much.

I have a two cheap meters and if you keep them in liquid, distilled is good or ro not sure about rain, all the time. It will help keep the meter working for as long as possible. You don't want the tip to dry out.

I'm on 24 hrs btw. I installed the large fan yesterday.. the plants are not hot. Around 80. Could I still have to much light? I also dimmed the light to 250w setting. Are young plants more susceptible to light stress? My large plant seems fine. I just transplanted it.

I think the leds are really no more than 200w
