G13 Haze quarantine grow :^]

QUESTION TO EVERYONE READING THIS: My tap water is pH 8.3 (yes I know right ?!) Adding the BioBizz nutes brings it down to pH 6.2 - 6.4 depending on the amount which is great. Now, I dont really care about runoff pH that much, doesnt tell me a lot imo but I measured it twice, last time it was 6.8 this time it was 7.1. Is there anything to worry about or is that just irrelevant? Thank you guys :) Day 48: Watered the G13 Haze with 650ml Water and 2.8ml / l BioGrow, 2.8ml / l BioBloom, 0.7ml / l TopMax which is the equivalent biobizz week 7 feeding schedule with 70% strength on BioGrow & TopMax and 90% strength on the Bloom. Therefore, dont mind the leaves hanging down, I just watered before taking pictures. Also redone some of the LST by changing the "angles" of the side branches to use up space more evenly. Tied down a bit more aswell to even out height differences. Looks great so far, but the G13 Haze is quite a bit behind in budding, the Liberty Haze is throwing Pistils everywhere, the G13 Haze just started showing the first noticeable preflowers with pistils on the nodes. Day 45: I really wanted to try serious and "professional" training methods. Defoliation was obviously needed, I couldnt even see what was going on below the plant. Removed all leaves except on the top 2-3 nodes of each branch. Then I did some heavy LST to move the side branches to the outside for filling up space. I hope the center will grow some branches at some point. MOST IMPORTANTLY, since I wanted the main branch to slow down growth a bit, I twisted and "mashed" it between two fingers until I could hear a snapping noise and the stem became weak like gummy. It takes a lot of courage guy! A LOT. But it seems to have worked, the stem is not broken and I managed to tie it down without bending the whole plant. I am so excited on how this is going to turn out. ~Watered 600ml today Day 44: So yeah, definitely stretching ! The internodal space is way bigger than I'm used to from growing short indica quick ones. Funnily enough, the G13 Haze does'nt give off any smell at all apart from typical "green plant" smell (Just noted that because the Liberty Haze smells quite strong even though it doesnt form buds yet). Did some very very careful LST which looks good for now. I want to remove a lot of leaves and little side branching from the bottom as soon as the plant grows a bit bigger so I can access the bottom part better.
