Hello rollitup, my third grow and I've found myself looking for advice! Got a nute problem..

6 plants, 2 Northernlights, 2 wonderwoman, 2 blackjack

4 weeks and 1 day into flower

600 watt HPS + 4 90 watt leds on sides..

Humidity is back up to 40% after being down to 15%give or take for bout a week(I know I know)

temps range from mid 70s to mid 80s at day(Very little time over 85 degrees) 60s 70s at night

Im using subcools organic super soil(a third on bottom and an organic base bag soil on top two thirds) in 7 gallon grow bags.

I water with rain water, about 1-2 gallons each plant just over once a week.. Maybe not often enough?

ph of supersoil was 5.9-6.0 before planting- Have not checked it since.. thinking that this ph might have caused nute lockout!? I know rainwater is acidic so it could not have been helping.

Anyways I'm getting yellowish brown crusty spots on my leaves. The northern lights is the worst followed by the wonder woman and then the blackjack isn't too bad.

Calm down and slow down.. You are doing tooo many things...

Cut nutes in half for a few days and see what happens...

Im curious also because i have the same issue,i'm leaning more towards it being a deficiency rather then too much of something. BUUUUTTT im a total noob myself so i'll shut up and wait for more input.

Thats not over feeding... you look like you got multiple problems
humidity, lack of airflow... those LED's like that on those plants honestly probably hurting more than helping, could use some epsom salt or calmag in your water... stop foliar feeding or watering with lights on.

It's super soil so I don't fert, Just rain water with a little molasses every other watering. Since subcools mix should have a good spectrum of nutes, shouldn't this be a ph problem? I need to get this straightened out because I have more of this super soil left to use for my next grow and, with the visible leaf damage, you can you can see where the problem lies with that plan.

my guess would be they are probably just finally SHOWING the stress that the might have been feeling from a very low rh% but i dunno for sure, you should get that 6 down closer if its not too warm, my 1000 is closer, but on a light mover. WINING =):clap: so you are on day 29 of 12/12?

I thinking it's your ph of the rain water.
You should check your water's ph~
Another possibility would be your soil,
is it prenutrientized like Miracle Gro?
