Been having a problem I'm about 3 weeks in to flower and my plants are progressively getting worst the leaves are yellowing pretty rapidly lower leaves to middle leaves it's not underfeeding. Or over feeding I'm guessing either pots are to small for the plants and there getting root bound or I was using ph tap water maybe abundance of chlorine. Any help would be great

Roots organic soil

Canna nutes full line

Flores- cannazyme- pk 13 - boost -

Feeding below the high end of recommendations I'm at around 1.3 ec

4 lec sunsystem lights in 3 gallon pots

The temp is Def an issue I have an open ac duct I use to keep it a little cooler in there when the lights are on but lights out the duct stays the same so the ac is running when the lights are off that could be it

Yeah, not only could it be, it totally is it.
Any yellowing, which I really do not see in your pics, is usually N deficiency.

I think using a little more N in flower than some schedules suggest is beneficial, but the fertilizer industry seems to disagree with me.

( In coco I run a custom mix I came up with, it breaks down to about 4-3-5, from seed to harvest. It works fuckin' great. I know other growers, with a lot more experience than me, who use similar systems. )

Don't let these companies force every one of their products down your throat, you probably only need two or three things from whatever lineup you choose. I typically use pure soluble chemical powders (MgSO4 and MKP) and powdered fertilizer mixes. Occasionally I will tell hippies it is organic, as an experiment, and they love it. They can't tell the fucking difference because there is none. I am actually running organics right now, though, because...not sure why, honestly. I couldn't get the coco I wanted, so I decided to do a soil run. Suddenly realized I can tell people its hydro, lol. Did I rant? Sorry.

THe purple you get from magnesium deficiency tends to be more blotchy spots.
I can't tell if the veins are looking white too or if it is just the contrast with the purple bits.
If it looks white, increase the micros you are feeding it, as it then has a problem with one of the metals.

I'm not seeing anything major wrong. As long as you didn't do something bad up to now, consistency in parameters is the best course of action.
