Yellow and crusty leaves
Hey dear community, Why is my plant not recovering? I even adjusted the ph of the watering and add cal mag. Every week it’s getting worse and I don’t see any improvement. I use the fertilizer from Bio bizz and light is far enough away from the plant. Temp and humidity are fine

What do you think the problem could be?
There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

Leaves are turning yellow during flowering - is this an overwaring issue?
About 1,5 week into flowering the leaves have turned yellow, especially on the outside. The leaves in the middle are still oke, lower older leaves are dry. Could this be overwatering or something else? I gave around 1L/day, coming from around 0.5-0.7l/day the week before.
