If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Deficiencia de calmag/nitrogênio?
Good evening, what's going on with her? Calmag/nitrogen deficiency? It's also been very cold for the Gorilla strain, will she hold up? The runoff pH is within range. I've been waiting almost a week between waterings because the temperature with the lights on is around 20°

Small red spots on top canopy leaves week 4 of flower
Deficiency of some kind. Leaning more towards a calmag shortage or even a phosphorus deficiency? Any thoughts? Small red spots with minor yellowing of leaves in week 4 of flower.

overnight yellow leaves with brown spots
These leaves (about halfway up on #1) turned yellow with brown spots overnight. I didn't check the soil before giving it nutrients two nights ago so I was wondering if it has to do with overfeeding. The soil is damp and kinda packed together. Any idea what's going on?

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

Yellowing plants
Based off week 2 day 7, does this look like an over watering issue or something else? This was the first watering where I soaked their containers. While they were in solo cups I tried to keep watering volume low.

Nitrogen deficiency??
Looking like I have a nitrogen deficiency. Thoughts and what do I do to correct other than what I've done already with a top dressing off earth worm castings and blood meal?
