Yea looks like calcium def to me, sometimes if the ph is a little low and doesnt get a chance to flux above or around 6.2 in hydro it can happen. But since the other plants are happy from the same res i would say just up the calcium dosage a little- so phenotypes are hungrier for it than others.

Plants with different needs sharing a res can be tricky- this is where foliar feeding can come in really handy- just spray the plants that need it without the risk of burning the others

Yeah, I like to keep them in separate reservoirs. Can always add a squirt of this or that...

I don't suppose you could get us a closer pic of them leaves? Oh, and one of the underside of the affected area?

Thanks Tunda,

I was looking for pest evidence as well. That's why I wanted to see under the leaves, but it looks okay so far. I am concerned about the white spotted areas on the leaves where they attach to the stemmy part of the leaf. I do think there may be some cal mag issues as with most led's, but keep an eye on them splotchy areas.
