What are these spots?

Professor_Daankstarted grow question 5y ago

What are these little spots? I only have them localized on this one leaf (and one plant out of three), and haven't seen anymore. I'm more curious than anything. Tips to fix? Don't worry?

Do you have any idea what the light measurement is “ppfd” at the level you have your lights? Looks like your leaves are curling up a bit so I’m. Wondering if this is heat and light related

Привет, друг! 👋 Это начало дефицита фосфора. Решение проблемы: 1. сделай ph своей гидропоники (без субстрата) 6,2-6,3ph 2. внеси изменение по добавке bloom - 0.66ml/l Удачи, друг! ✊

Is this Cal/Mag deficiency happening?The taller of the 2 Strawberry Bananas I think is showing some Cal/Mag deficiency so I added 1tsp per gallon when watering. There is only seven leaves exhibiting this on the plant and no other plants have this and everything has been the same for all plants so curious whats up?

In the middle of the picture from day 25 there is something weird going on with the new growth (next picture is more detailed). One side is growing really slow, the other looks like it never grew/was eten/something. It is kind of brown/red-ish. Is this a deficiency or windburn?

Brown marks on leaves and drooping, sad plant Some issues developing with the FCxForum strain, some brown markings on the leaves, no signs of this on the DeezNugs. I know the pics aren't great but anyone have any idea what they could be? I'm starting to think they are water splashes but one of the FC is drooping quite a lot.

Pineapple auto in soil tiny brown spot My pineapple express auto is well into flower but the leaves look sick with light green patches and tiny brown spots appearing on some of the top leaves. The brown spots dont rub off on finger so don't think it's fungus. Not sure what I should do, it's getting flower nutes.

One of my plants (picture included in week 2) seems to have something wrong with it as shown by the white lines/bright discoloration on the leaves and new growths. The leaves themselves also seem to have a thinner shape compared to the other 2 plants. Is this cause for concern?

Holes/Spotting on leaves Noticed some holes and some spotting on a few leaves. Initial thought was spider mites, but based on pics not sure if that's the case. Also thought it could be areas where water beads were on the leaves and burned through (as the holes go). Not sure about spots. Thoughts?
