Cutting damaged leaves away or not?
Hallo, I have some spots on leaves due to calcium deficencie and it has stoped spreading above leaves by adding calmag to the nutrient solution. We talk about 2 single leaves per plant (max 3 leaves). Should I cut them of because they need energy to recover or does it not care?

Cal-mag deficiency?
Hi guys, I think it's magnesium deficiency (early flowering). I have also noticed a few small burnt spots on the leaves. Is this time for cal-mag? Or am I reading this wrong?

Nutrient burn/not enough nutes or normal?
Should I be concerned about the dying leaves near the bottom? I first thought it was nutrient burn but I’m now doubting myself!

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Leaf issues. More specific question
Asking again but I'll be more specific: I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/brown color along the sides of 1 of the true leaves leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Damping off? Thoughts?

Leaf burnt edges
One leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

phosphorus and boron anomaly
Could someone please explain the precise mechanism underlying the phosphorus anomaly? As anticipated, availability decreases with increasing pH, yet it exhibits a sudden surge at pH 8.5. What is the exact (bio)chemical rationale behind this phenomenon? Boron has a similar pattern

Hello Beautiful People! Two days ago I noticed in the morning that one of my Raphael plants had droopy lower leaves. I watered it with some herculean harvest and after night time it bounced back. Today it is droopy again. Is this a problem? How can I fix this? Thanks a ton !!!

Unknown rust on 7th flowering week
This started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?
