Sorry just working with what I have on hand lol. (loosely tied, see pic)
Low temp at night is 18-19 Celsius and day temps are 24-26. Strain is Purple Haze so that could explain the purple tips! Just wanted to double check I'm not running into more nutrient problems. Thanks for your advice so far Daskahn, really appreciate it!

Here's the purple that I'm talking about. It's only on one fan of leaves on one plant so far

Yeah I think the purple is due to the strain.. so your good on that
mad the plant grows keep an eye of your fishing line.. basically your stem can grow(get fatter) and the line may tighten and cut into it(if it’s to tight) but right now it’s ok
