Got some minor leaf burn this week. Only a couple leaves, I thought it might have been from being manhandled during the LST training, but not sure. What do it look like to you?

I still can’t determine whether this is a heat related or Nute burn issue. Is it that temps are too high causing a Nute problem? I’ve done all I can to lower temps.

Leaves curled up?
Leaves curling up? Not all.. a few we have moved the light up and I brought the plant down some. It started earlier and the light fixes it but now we are doing it again... no discoloration or wilting..

Will my plants survive?
I am on week 4 of my white cookies and they have stopped growing. Very small and weak looking but still got colour. Having over watered them can they be saved? I transplanted them in dry soil and left them for a few days but no growth is happening.

Mancha en hoja
A que se debe que estén así algunas hojas? Es deficiencia o exceso? Regaba con 1000 ppm pero vi algunas puntas quemadas y color verde oscuro en las hojas así que lo fui bajando poco a poco hasta llegar a 500 ppm, y hoy note esas manchas(el agua drenada da 750 ppm)(coco y perlita)

Brown spotting?
Hey everyone! My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean? I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

White snipes on leaves... [ MAYBE THRIPS? SHOULD I USE POTASIUM SOAP? ]
Hey guys! Do you think these are thrips? The leaves have these white snipes already since some days ago. Also, If you look carefully, there are micro white things on some parts in the leaves that could be the thrips themselves. I'm thinking of adding potasium soap for this.

Chewed up leaves
Wondering if I should be concerned? They have just entered flowering, I have noticed a few leaves bearing this issue. I use ties which have ripped some leaves due to me not being gentle, and I spray a mild cannacure solition regularly.
