First time grower help please

[Greentrees50]

Hey guys first time indoor grow here and I'm in need of some help, I have 2 autoflowers that are about 5 and 6 weeks old. My problem with the plants is especially the younger one have some very yellow fan leaves towards the bottom. They also have some brown/rust spots on the leaves.

Nutrients using =Advanced Nutrients grow,micro,bloom at 1/4 strength and (voodoo juice and B-52 at 1/4 strength just for the younger plant) I also have big bud and overdrive. The soil is half pro mix and half foxfarm soil.

Any inputs from someone on what could be the problem for these plants and what I could do would be greatly appreciated.

A pic in normal lighting will get you a better diagnosis...but looks like cal/mg is needed. Led lights seem to make your plants cal/mg whores

The yellowing bottom leaves could be N def, but i can't see anything in that blurple lighting!

Definitely looks like a cal/mag deficiency

fox Farm is known for having ph issues, that being said it is older lower growth I see that a lot and just remove them or let the plant consume them. Most often PH is the issues of deficiances and its usually a lock out not a def.

A pic in "normal" light is definitely good; also what is your runoff pH and EC at?
How moist are you keeping your medium?

Here's your pics edited a little and I think you have more going on than just ca-mg

Looks like maybe PM on close up pic. Get you a lamp in there turn blurple off for pic. Then copy and paste infirmary info to fill out. Then we can help. @Waira is the go to guy though.

I'm seeing powdery mildew too, possibly overwatering/sitting in water, she's pretty droopy.

Thought it was droopy also, but towards end of day they will drop. But more than likely needs more air circulating, less frequent watering, upped ca-mg and more but don't know without more info and better pic
