I need your expert opinion & feedback to identify the problem

[morphin]

I have 12 clones right now and 2-3 of them have weird issues.
I feed them with "Advanced nutrients grow micro" every 4 days. I have no idea what is the problem.
Room temp is around 30-32 centigrade. During lights off temp decrease to 25-26. Humidity 50%


Can you please help me to identify the problem?

Bottom one kinda looks like The Borg (Spider Mites)

Yeah spider mites, or something splashed and laid on the leaves too long, you get that crusty white burn if you don't notice it soon enough.

Just micro or micro and a and b?

Yes I were have White Spider Mites before. It must be.
I was confused because it wasn't in the others and seemed a bit strange.

What do you think about First photo?

I'm using Just micro and grow for veg.
After moving to bloom area I also give Bloom and Bat fertilizer too.

I have solved 3nd problem but 1&2 still continues.
I only use 2ml/L AD Micro "2-0-0" and Grove "1-0-4"

Also in the flowering room I started to see some problems on lower leafs. They're in the 5th week of flowering.
As you can see They're too dry and looking terrible but they shouldn't be.

I feed them every 4 day (Grove "1-0-4", Bloom "1-3-4" and bat fertilizer "Carbon 12% - Nitrogen 1.5% - Potassium 3%" total organic 25%)

Is could be Nutrient Lockout problem?
