Any ideas on whats going on here?

Pretty much every plant in my room goes through the same thing. Dark leaves with blotchy rings on some. Some get bad and kinda twist up. I thought it was something in my water and got a filter (boogie blue plus) which seemed to help but I'm changing them out monthly and this time didn't seem to really work with the new one.

My room stays around 83° 60‐70%rh.
I use sohum soil in 10gal fabric pots as a final pot going from cup to 1 gal to 2 gal.
I ph my water to 6.3-6.5 using lemon juice to bring it down.
My water comes out of the tap at about 7.6-8.2 and has a ppm of about 80-100.
I run HLG rspecs in my veg room.

In the 10 gallons I've given generally 3/4 gallon water every other day (they're pretty big plants cause my flower room took longer than expected.)

My room is 150 sq ft with 2 wall oscillating fans and a fan on the floor in the back of the room. My exhaust system is an 8 inch ac infinity cloudline which is set at around 4 and there's a 4x8 intake vent which pulls air in from the main basement area.

I occasionally top dress with roots organics uprising formulas.

They still grow but don't look lush or nice a lot of the time. Any ideas will be appreciated.

I'd guess Mg deficiency but the real question is why. Especially with too much N. Anyway I'm hydro so let's let some of the soil guys help you.

Thats kinda what I was leaning towards but like you said, why is the real question here

I would do a soil ph test, just to rule that out.. Maybe do a foliar with epsom salts, 1 tsp per gallon..
Why? is a big question!

I've tried a foliar of epsom salts in the past for what seemed to be the same issue with no results. I guess it wouldn't hurt to try it again though.

Why water so often with a 10 gallon pot? I am in 3 gallon pots and water every other day, in 10 gallon pots you should only have to water every 4 or 5 days, depending on plant size, growth stage, humidity and temperature.

I can't say this is the cause of the problem, but watering properly will eliminate watering as a potential cause of any issues, and give you much healthier and more vigorous growth.

The fact that you’re so into this and still having problems… ‍ Whew. Jesus, take the wheel.

Honestly figuring out how to water correctly has been the hardest part of growing for me. I water once the pot feels light which is every 2 or 3 days usually. People tell me I need to water more often, less often, more water, less water... it's hard to figure this shit out cause I get so many conflicting opinions. Do you think maybe I should give a little more water at a time and let them dry out longer? They usually feel quite light after 2 or 3 days

Saturate the entire media every time you water, don't water again until it is very light...but you have to start with getting it all wet...even if that means letting them sit in water in the saucer for half an hour so you know all the media has absorbed all the water it can. Make note of how much water this takes and use that as a base going forward.

Honestly I think you should use smaller pots until you get a hold of this concept.

After transplanting from the 2 gal, go into 5 gal and learn how to water those.

pH issue us by bet. Why? Well more often than not when u see multiple deficiencies at once it’s either the following;

Too much or too little water
Wrong pH
Over feeding.

Go through those 3 points and I’m sure you’ll find your answer!

I used to struggle with when to water because I am terrible at estimating the pots weight by lifting it, and I am disabled so I really can't lift anything.

Instead, I use a small scale:



I know the dry weight of each pot size, with a 3 gallon pot I just slip this scale under the pot in the tent, I don't even have to move the pot out of the tent. This helps me know when to water every time.

For instance, the last grow I had one plant taking water every 27 hours all thru flower, the other plant was every 48 hours, without the scale to confirm the plant needed water every 27 hours I would've been skeptical and doubted myself, but the scale doesn't lie and it worked out perfectly.

I agree with soaking the pot until runoff, but I would never let the pot sit or soak in runoff water. Ever. YMMV.

First thing I'd do is stop using the lemon juice. If you're in good soil like it sounds like, it will buffer itself.

And if you want to use citric acid just get citric acid. It's cheap as hell.

But that looks like low pH to me.
