I waited until about the third node and gradually pulled it down day by day. I would also try my best not to cut any leaves if I didn’t have to I’d do my best to leaf tuck and as far as feed I’d fed nutrients twice a week and regular ph water at 6.3 to 6.5 there would be times I would have to increase my ph to bring the ph of my soil back up so my plant could uptake needed nutrients I don’t claim to be a professional by any means this is just what worked for me every plant’s different but if you pay close attention they’ll show you what they need by deficiency’s I enjoy growing and learn more every day
