My strawberry pie auto has had rust-colored spots, burnt leaf tips, and thin leaves since I gave her mycorrhizae.
What could this be?
(the single leaf shows it the most)
The other grower has it spot on its too much or not enough cal mag by my eye I would say too much rather than too little like the grower has stated easy to fix just flush her next time you feed then reintroduce it when she dries out. job done :) Good luck nice looking plant :) 👊
Having had the same I done some research and asked a similar question.
The research said it could be fungal, if lower leaves are dying and rust comes off on your hands
Nute defiances - again lower leaves dying and leaves curling
Or nute burn.
When I posted on here they seen I was in week 10 and said it was cal mag leaving the plant.
Not sure if this will help just my experience! Hope it does though
I believe it's cal mag leaving the plant as I've reduced it in the feed as per my remo food chart
