pH is 5.5 but i have nutrients deficiency. Can it be the cold?
One of my plants (in soil) has yellow leaves and brown spots, it is possible that it lacks Ca and Mg, but it's pH is 5.5. I wonder if this nutrient deficiency is caused by cold water (now I'm using it warm and waiting), low temperature or high humidity.

Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage
At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

What is this!?
Hello there. I have, as you can see a bit of an issue regarding my plant. What is this? As you might see, the lower leaves seems ok, and that concerns me even more. I have flushed her properly and then gave her adequate amounts of feeding. At first I thought it was lack of P.
