Deficiency Problems

[EatPizza]

Hey all!
I'm growing out som Diablo OG. My plants are about 3 weeks into flower. Running into some deficiency issues. Here's my set-up...
-ebb&flo
-RO water
-resevoir PPM is at 1100
-resevoir temps range 68-72°F
-4" rockwool cubes
-humidity is in range of 35-45%
-lights on temp is 85-90°F
-lights out temp is 75-85°F

I'm using the AN(micro,grow,bloom) ph perfect base nutes. Along with a line of their supplements.

I've included photos in what i think might be a cal/mag and nitrogen deficiency.

Any input would be greatly appreciated!

Thanks all!

Yea bro you gonna have problems....

-Your ppm in resivour seems low for this stage.
-Your humidity is low too low for the stage of flowering your in.
-Your temps too high with lights on.

I don't know about your nutes and weather they need added cal mag to them...

You may have some other issues... that I wouldn't be able the know of from what you wrote.

-root problems
-irrigation problems
-lighting issues

I would defiantly suggest with getting these factors dialed in.

The plants don't look underdeveloped by any means so I'm sure you can turn save them.

BUT... if this problem continues you will sufffer in harvest greatly.

Good luck.
