early cal/mag deficiency?

is this the early stage of cal/mag deficiency? I water with RO water and there is dolomite lime in my soil so i dont think lockout is the problem. they were doing great until i started with RO water a couple of weeks ago. came back from a couple day trip for xmas and this is what she looks like. thanks for any help

i realize the picture is kind of small sorry. there are little faded brown spots forming all over some of the fan leaves

Dolmite lime is cal/mag and is good treatment slow release but works as treatment for this deficiency, if this is already mixed in your soil i doubt thats your problem, cant tell you wat your prob is cos your pics minute.

get better pics up that ones tiny like you said, how old are the plants? what stage of life are they in? are the spots on old leaves at the bottom or new growth on top?

here is a better picture

it looks like calcium def,cal/mag should fix it.

alright thx a lot.. guy at the shop told me 3ml per gallon. is that correct?

plants are about 2 months old and are in veg. spots on the leaves are in the middle but new growth hasn't started to show signs yet

I'm having a similar issue... one small spot that is slightly orange... wondering if i have a cal-mag deficiency myself.

Good job everyone. CAlMAG for the win
