ive had many problems with this...

this has been happening alot. seems like a cal/mag deficiency but it never gets fixed. it normally happens a little later into flowering than this guy she just started to flower 3 days ago and now she looks like this. about to lose some leaves. i mix my own soil. i have a good amount of dolomite but not insane amount of it in the mix. so i cannot see it being a abundance. she is alot very light green which is a N deficiency i have added nitrogen twice now as biothrive grow and nothing has happened. I also use led lights to grow them. maybe it is the led causing this.. is it possible there could be some type of lock out? what do you guys think form these pics?

Whats in the soil and whats your pH? How wet? I don't use leds..I'd be curious if a couple added cfls would help.

the soil is a local potting soil of 5 different composts. and mixed in is ancient forest compost, EWC, high P guano, bone meal(6-9-7), dolomite lime, some epson salt, and some all around fert with alot of bacteria in it called jobes(2-7-4) i feel like its an all around good mix but i could be wrong hopefully i am not.

K, I'll ask like Coho, what is your soil PH?
I can't tell how tall it is, and you only said 3 days into flower, but they look kinda young to have that much goodies in the soil AND have fertilized twice already.
