If in soil no. Every other should work unless you have coco in substrate mix.

Continuing calmag deficiencyWhat 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

Rusty spots on fan leaves overnight, what is it? ️Last night I used some old but clean looking wire to bring branches in to the main stems.
This morning there's now little orange rusty spots everywhere. Is a soil grow, 6.3 pH used and same run off with Cal Mag every other feed. Taken the wire of at 6am in anger, was it that? 😡

Deficiency ProblemsI don't know why they suddenly show so much deficiency.
Do I need to readjust the PH level or add more nutrients
Could it be because of the stronger lamp?

Hey, anyone got any idea or clue what's going on?I thought it was a manganese or iron deficiency from an early watering with high pH.
Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly.
She seems to be getting better slowly.. I think.

Leaf issues. More specific questionAsking 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?

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese.
I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.
