What's up Casper, good to see you growing again bro... Just checked out that strain looks like a good one, you know I love the purps
Regarding the nutrients, I typically start the bloom nutes around week 5-6 and usually just keep them at 2ml/l. I start adding bud candy soon as I switch to bloom nutes as well, for all my supplements I've just been running them at 1ml/l.
Your plant seems to be looking good to me but hard to tell with the LED lights, if you can take some pics with them off next time it's a lot easier to spot any deficiencies.
Anyways, good luck with the grow man I'll keep an eye on it... I just started a new grow myself after a 6 month break from growing, link is in my sig if you want to tag along.
Heres Day 49.. leaves are starting to turn purple when pics are taken outta the box.... added AN Big Bud and Jamacain bat shit in the topsoil mix for week 2 bloom feeding.
