You have nute burn. Test runoff and flush if runoff is hot.

* Spots (pic 4), on only 3 leaves of the plant at the top. Last week, before lights out, I misted. By lights-on time, some parts of the plant were still wet. Is this some water burn? Tap water is PHd and ~215 ppm (plenty ca/mg) * Any insight on those yellow tips is welcome! :)

My leaves on plant getting yellow at week 4. Gave her a flush for a few days with a pH of 6.0 but the run off stayed at 4.8. continued flushing with a high pH of 8.0 then the run off went down to 5.8. I did add peat moss to my Coco/perlite. Could that cause the pH to be low?

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.
I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?

Can anyone help identify this tox/deficiency?
Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

Dark spots starting after feeding. Concern? CalMag, first time feeding with more nutes, so it might be nute burn yea but is it a concern. It started moments after watering, or that's when i noticed it. On a few leaves. Earlier on i cut lower buds and did some defoliation

Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures). The box worked fine for several grows
