I would classify myself as a beginner grower although I have done a few crops in my lifetime, and I have never encountered anything like this.
My plant is just starting the flowering stage and it's been a few weeks that I've been noticing on some of the leaves these black/brown burns on the tips as well as some green/yellowish
leaves in some of the lower branches.
Overall the plant is looking good. top of the plant is good, good green leaves but I don't know what is the cause of these problems.
Nutrients? Temperature? Roots?
I am clueless on what I could do... the only thing so far is that I have been removing the leaves that have these problems.
I hope you will be able to help me... thank you very much
Well honestly it’s going to be nutrients as flower begins plants uptake nutrients and take away from leaves in order to feed flowers so nutrients and thin out excess can leaves allowing more food for bud.
