Normal or should I be careful?🤔
First time I see these little dots on the leaves, can anyone identify them or is it nothing to worry about, as I'm thinking? 🧐🤔

Root rot or pH imbalance?
This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Weird leaves
The leaves of my plant look strange, I'm not sure if it's CalMag or something else. I recently overfertilized the plant a little..... I am also fighting tripes on the plant at the moment Could it also be the PH value? Thank you :)

Hydroponics, i need a second or third pro opinion. Just a Deficiency? bad pH? (I alreadt did a partial water reservoir change tho)
Yoyoyo! If someone of knowledge could help me here, I would be grateful So I think it's a Magnesium deficiency, caused either from my too low pH (5.2) or too much CalMag (only used 1,5ml on 10L) I gave a more in-detail description on my diary. lower leafs are "crispy", not smooth

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Phosphorus Issue?
Slurricane is having a phosphorus issue and not drinking water as fast after transplanting. I’ve been feeding cal mag every water and thinking it’s a root zone issue. Should I apply stop watering and apply a follar feed of 3 part general hydro nutrients?

Interveinal chlorosis and dead spots on leaves, deficiency?
This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Fasty
One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Strange clear spots on seedlings leaves
My two seedlings are showing this strange clear spots, I can't figure out on my searchings. Maybe water droplets burn when I mistankely sprayed them with lights on when younger. Or it looks something else?

Sick plant, could be temp, nutes, too much water?
Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?
