What the hell is going on?

So last night I found a hermie and tonight I find my leaves spotty and its pissing me off. With only 3 left I don't want to lose another one. So they are in a mix of happy frog and ocean Forrest and under a 600w hps. My best guess is a mag sufficiency or am I way off. I've never had any issues before now 2 in 2 days.

Take pics with normal light.
Try giving us information to work with.

Yea, need better pics without hps on and more info.

Mine had the same "yellowing" spots on the edges of the leaves, I added P and K last water and its stopped the yellowing significantly.

I had an issue with yellowing tops and yellowing spots...
I turned off the fan during the dark period and foliar fed with epsom salt at 1 tsp per gallon and cal mag at 1/2 tsp per gallon... ph'd to 6.4...

when the lights came back on I saw some improvement. I am still trying to find out exactly what my total problem is. But the foliar feed helped some flowering plants out.. overnight.

I think my strengths are kind of high. but it helped. It left a little residue on some leaves. I might clean that residue off soon and do it again.

Here's a better picture.

That looks like a K deficiency, and an abundance of N.

 

[DeeTee]

It does look like potassium (K) deficiency

Where it is on the plant is important. Check out the images in this link:

Also just treat it with some Cal/Mag it won't hurt the plants and can be given anytime. But don't expect the already affected leaves to get better, they won't but the new growth should be healthy if that was it.

Should the bad leaves be removed??
