What’s causing this?

[Huntz88]

Green crack grown outdoors. Got a couple branches that have leaves that are multi coloured. It’s not on all the branches though.

I’ve posted a picture of one of the leaves.

Hoping someone could give me some idea of that’s causing this and some tips to rectify it.

Thanks

Have you gotten nutrient solution on the leaves, or water? It looks like that kind of bleaching from the nutrient solution (or water magnifying the sun). I've seen something like that in a tent under lights.

everything ph'd correctly?

To be honest I hardly water it at all as it is outdoors. 95% of the water it gets is from rain.

Guess I could Test the ph of the soil though
