Looks like the first signs of nute burn. Flush them with balanced PH water

Could also be magnesium deficiency. When you flush, next feed, give half recommended Nutes and calmag

All the spots, holes, brown spots, etc are just part of a normal grow. I’d guess the overall drooping has to do with watering/root issue. You should clear out the bottom canopy (to allow more air flow), get the pots off the ground (with some sort of grate), remove the drip trays, and make sure you’re allowing the pots to sufficiently dry out between watering.

tonights pics of the problem child you guys have more exp then me but to me this is what it seems like https://growingexposed.com/cannabis-doctor/phosphorus-deficiency/ maybe someone could explain to me why this would not be it

What are you feeding? I see a Mag def, and maybe Nitro, but it's difficult to tell with the color lights.

 

[SDJ99]

I don’t think that’s phosphorus deficiency, that makes the leaves turn purple/blue in the middle.
here are mine that have phosphorus deficiency from overwatering

 

[ComfortablyNumb]

Phos def, usually shows up as brown patches.
Phosphorus, Potassium and Calcium look almost the same.
So, a nice tea is called for here. Mix a bit of each in some water and let it sit in the sun for 2-4 days.
If it makes you sick to smell it when you open the lid, it's ready. It should smell like a sewer.

Look at what it is sitting in each time u water it is getting stronger each time u water as that catch plate is full of salt

 

[Ghosttrainx]

If u are doing that once a week food and rest water just like out door u need that salt to flow away and problem solved

Root rot sitting in water burned roots from to high salt build up

Also phosphorous deficiency usually turns stems red or purple

+1.. though you don’t really need to defoliant

Easy fix use pot risers under the pot ... Dry roots aids in plant health .

I find actual phos def very rare - usually problem stems from something else - to much calmag can easily cause confusion! I’m not familiar with your nutes but do have some ppm questions and water questions - 1- do you use tap water sorry if I missed it, ? What’s the ppm of the water you use before any nutes?
I ask because I fear a toxic environment not a deficiency but that’s my opinion - good luck there’s some great guys here to help !

Lil disclaimer- if someone ever contradicts me, I would trust them over me at this point in my learning how to properly grow.
I try my best to help from my own research or experience with my first grow but if it’s incorrect information, I apologize
