What deficiency is this?

I've got this GG4 girl at about 5 weeks and so far she's been healthy but I've noticed what looks like the beginnings of a deficiency. Or at least I'm assuming as I've only been giving it RO water since I potted the clone. Im thinking its calcium or magnesium but I'm not sure

You sure just ro water, it's very dark green? Those ferts have tons of nutes in them, but they're good too. Ok just want to rule out the usual cal mag...not discrediting anyone, cause it def could be.

What are you using for light, how close as it looks like that plants is lacking nothing, but too much light, and its bleaching

Even though it's dark green doesn't mean it has enough Mg. That totally looks like the beginning of Mg deficiency to me.

Props to the OP for catching it so soon. I'd give it cal-mag or epsom salt. An epsom foliar will have the quickest results, but it's not really necessary.

Just try a light dose of cal mag and go from there go easy start with a light dose its much harder to come back from an overdose than to little of something

I get that, its what I said. Just wanted to rule it out, based on my experience. I had the same issue moved it up 3" and no problem. Much respect.
