Yellowing & spots question & pics

Hey ladies and gentlemen, anyone have an idea of what this could be?
The lower leaves are turning yellow and getting brown spots. Also, when should I repot to 4 gallon pots?
(3) Nirvana bubblelicious
2nd week of flower
Hydro, Coco only
Fox farms trio
(10) 200w cfl
2 gallon pots

Thanks everyone!

Discoloration is not from the need to be repotted.
My suggestion is to up your nutes or feed more frequently.
You don't say if or how long you vegged, but to me, that's at LEAST 3 weeks from needing to be repotted.

Should repot before you flower.
Are you feeding her? Are you checking the ph and what is it?
It looks like a nutrient deficiency.

I would look in to the PH as well, PH issues often show up as deficiencies as the plant can't take up what it need if the PH is off, in coco your need to treat it like hydro, water need to go in at 5,5-6,2 (aim for 5,8 in veg and 6 in flowering)

That is definitely a deficiency of some sort so I would up the nutes. If that don't work then flush could be lockout. Deficiency are hard to figure out because it could be lockout from ph problems or even overfeeding them or even to much water. Let us know if any of our suggestions have helped and what the problem was.

Yup, you need to put more nutes in. You have all NPK deficiency. Use at full strength until the deficiency stops then back off to normal regiment ( half strength or so).

I would dose her ass with some micro nutes, and or "Dyna Gro" fixes anything! Lol...

Thanks peeps! I'll try to give her more nutes.

My ph is at 6.0

Fox farm trio nutes...

This guy just fell of tonight. It was moist, not dry, just yellow as hell.


This is the bottom of #2...

I should say that this is 2nd week of flower.

I was only up to 1/4 nutes during feedings, which I realize from looking at my last grow log, is way off.
I also gave them a light mist of SM-90, 5/1. Just in case there's a gnat problem. I sprayed it and about 12 flew away... Probably not good.

Thanks peeps and I'll get back to you...
