Hi I've looked at ur diary but can't see ur growing medium...so I've zoomed into ur pics and I'm inclined to say cal/mag deficiency going on there, u have some purple tones on some of ur branching network which can sometimes be classic signs especially when your leaves are starting to go off green to the tones they are now ...hope u manage to sort tjis out my friend, most gardening places will have a calcium magnesium mix which can be bought together best wishes 🌱🍃
