Cal/Mag problem? or Nitrogen? Need help!!

Hey everyone, have 4 girls in FFOF 5 gal fabric pots and noticed some of the bottom leaves turning and burning. Also, every time I've potted up from solo, 1 gal, 3 gal, 5 gal ive used fresh FFOF

At one month from seed as of today. 2 og kush and 2 gold leaf.

2 600w viparspectra LEDs

Room stays between 75-83 depending on watering schedule. When watered fully it drops the temp for a few days, as it dries it gets warmer. Lights are on always on.

I'm using RO water (Have not used any Cal/mag at all because I was under the impression the FFOF had enough nutes in it)

As you can see in the pictures pretty clear I'm having some issues with the lower leaves. Anyone have any idea whats going on? Is it just lacking cal/mag which I started today? I'm also noticing some top leaf curling/yellowing... Nitrogen?

Take a gander and let me know what you think. All help is greatly appreciated!

Looks like there is plenty of N.

If you think they could be having a calmag issue, give a calmag foliar. You'd likely see a turnaround or stopping of symptoms a lot sooner.

Does that look like what it could be? Basically only the under leaves are showing signs of being unhealthy.

Cal

I would try not watering so often/as much. The curling downward of all your leaves is a sign of overwatering. Which in itself could cause alot of "deficiencies". I agree with his diagnosis just pointing out another thing to be aware of

It also appears your light is a little close yiu have some heat stress toward the top of your plant maybe move the light or get a fan on it

Thanks! I'm currently watering maybe once a week... The pots get light but I dont ever see any drooping of the leaves... You think I should wait till I see some droop??

Slight just to get a feel for its bottom line. Underwatering is better than overwatering. Still something i have ti get used to myself and I know I still have room to improve. Very hard ti withhold watering when u think theyre thirsty. I wanted to water my ladies 4 days ago they still can go a day or two thats almost a week before needing water. I kniw they werent overwatered because sgowed no signs just takes long for evaporatiin when roots arent drinking. All plants drink differently evem the same strain so try to individualize them. Sometimes i will add a splash of water on one to let it wait so i can water everything together
