I believe you are experiencing ph fluctuations. I'd calibrate your ph pen if you use one, if not I would recommend one.

They look ok. I would say 2 things, too much nitrogen and not enough pk, correct these and you should be fine going forward

Bei einer Pflanze sind die Blätter der Pflanze verbrannt an den Spitzen, die Blätter sind auch grundsätzlich dünn gewachsen. Interesanterweise ist sie Jetzt die Größte. Was ist bei da passiert? Alle 4 Pflanzen sind mit dem selben Wasser gedüngt.

Burnt bottom leaves
Found burnt leaves in all three plants. They are all from the bottom and fell from the stems. Not sure if it's a)lack of nutrients b)nutrient burn c)nothing wrong, just the normal process for shaded leaves. What do you guys think?

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Rust/dead spots
This girl, was overall stressed out from the beginning. Lights, overwatering, ph , wind burn, you name it. Either way all of the plants have long recovered. Still stunted tho. Plants have only received one 1/4 dose of veg nutes. Are the spots from lack of P and K?

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?

Is this possible nutrient burn?
Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

Deficiency?
OK so my plants are in week 6 to 7 of flower. I'm seeing what I thought was a potassium deficiency. The nutrient line that I am using is Remo Nutrients. I added an extra bit of Astro Flower (which has the most amount of "K" in it) to the last couple of watering top ups. DWC.

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.
