"An ounce of prevention is worth a pound of cure."

Is it the fact that I spent to much time under the HPS that I see the on sight of Iron deficiency? Or is it slowly creeping up on me? My observations are the veins are staying green but in between the veins it's turning a lighter green. Just afraid it's going to turn yellow and necrotic. These are four pictures of two of my girls, week and a half into flower. If you see it offer a tip or confirm I'm spending too much time under the lights lol.

have you tried CaMg yet?

Sorry I didn't list what I'm feeding. I haven't done anything but mixing some floranova veg and dyna-grow bloom. Trying to keep it as simple as I can, right? You think its a cal or mg problem though huh?

what size pot are they in? soil? hydro? looks like there missing some key nutrients... are you letting the pot dry out all the way before you water? need to give us the whole scoop. but there deff missing there full spectrum of nutes.. try a lil more nitrogen during bloom they still need it to grow.. you help us we help you..

Four gallon pots. They are the air pots or whatever they're called. They have the cones on the underside that are supposed to give more oxygen to the roots. Yeah the soil gets pretty dry before I water. I've been doing the weight test lately. Lifting the pots to see how heavy they are. I'm aware of the need for N during bloom. I've been adding some bat Guano every now and then too. Like half strength 15-0-0. Lights to are two 600 HPS and one 400 HPS. Dehumidifier runs and keeps the humidity at 50 constantly. Temps are 75 almost all the time with the exception of hot days with 80. I run c02 as well between 1300 ppm and 1500 ppm. I that is the scoop. Thanks for you help and interest.

Think I'll try hitting em with more N first see what happens.
