Yellow/brown splodgesHi there
My plant is still young @ just over 2 weeks now. She has these brown/yellow splodges on only one leaflet but the new growth is looking a healthy green, so im not too concerned at this point. I am curious as to what it is though. What would you guys suggest it to be?

Should I cut these off ?leaves are no longer crispy and dry but are still rapidly changing colour, not sure if I should cut them off or let them fall off themselves ?
if I cut them off would it be beneficial ?
not sure if the plants still putting in energy to keep these leaves on the plant or not ?

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Burned upper leaf edgesHi!
Dark spots appeared on some upper leaves overnight.
I don't think this is the cause, but I did a pretty heavy defoliation the day before.
the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish.
what could this be?

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
