what do you guys think is causing this to happen?

i'm getting yellowing of some leaves. thought i burnt the last set but these are getting fed less. or do i need more nutes?

ph is 6.77 i know its a lil high but would it cause this?

looks like a cal/mag defeciency to me...flush with water to unlock soil then give a shot of cal mag for 2 feedings...should take care of it...peace az

def looks like a cal mag def. but that could also be a result of ph lock out or zinc def kinda looks the same. whats your ph sitting at? check the nute problem on my second link.

thanks ph is 6.77 like i posted.

is that your pit dr.green? i also have one.

i'll flush tonight and get some epsom salt.

flush for 2-3 days...then hit with epsom on the 4th then the next 2 feeding hit with half strenth nutes...should take care of it...peace az

right on. thanks again.

cal mag will fix it, on the back of the bottle it has a dosage chart for soil and hydro and also an accelerated dose... I feed my plants the accelerated with every watering during flower til I flush and never get any yellowing... I once used just the suggested dose and got minor yellowing, nothing much. The shit works wonders.
