Anyone Know What This Is?

So at first I thought this was cal/mag defiency. But right now I dont have a ph meter or ph soil reader.

I've watered with some calmag twice now. Seems to have got worse since first calmag feed. I'll keep an eye on it.

Is this a deficiency or ph issue? I've been using sensi ph perfect line.

How long has it been since you last used cal/mag?

I've used it twice in about a week. Once with 1-2ml with my nutrient feed, and once yesterday with water feed containing 1ml of calmag

I had the same exact issue. Is your plant in flower? Mine turned out to be a Phosphorus deficiency. I also thought it was Cal and it got worse when I fed with more cal.

It actually turned out to be light/heat stress. I notices the leaves were curling upwards towards the top of the canopy and then i realised. I put the lights up higher, removed those leaves and still keeping an eye on the fine leaves to make sure it does not come back. As i got in and taken the leaves off, i could feel the heat on my back through my tshirt. If i could feel it warm enough, the plants would have felt it worse
