Russdog Northern light Auto

Hi guys, new to this game first grow so looking for advice and guidance, the pics are my northern light auto 17 days in, I'm happy with size I think, just concerned about the bottom two leaves that are slightly yellowing, any advise most appreciated

Hi guys day 19, would appreciate advice/comments regarding set up and nutes I'm using and general condition of plant looking at the pics, apart from the yellowing of bottom leaves that I now believe is quite normal I think it looks healthy enough? Someone commented before saying it looked like I am growing in soil, I can confirm I am growing in canna coco professional pro with 20% perlite mix, any comments or advice greatly appreciated.

So guys end of week 4 for my northern light auto, and so far I'm happy with how healthy it's looking, on day 21 I decided to try some LST on it, just a simple bend over to the side of the pot as you can see in pics, but I am now concerned about it's height and how bushy it is, I feel it needs to stretch more but have also read on various sites that small and bushy for an indoor grow is a good thing, so would appreciate your opinions and any input, the nodes just seem to be to close to each other, which just seems to be creating a mass of leaves, hoping that maybe this is a good thing, and she will start to stretch soon, as you can see my watering schedule averages out at 700ml per day, but I actually water every other day 1.4L with about 400/500ml run off, does that sound about right to u guys? I have also raised my light from 22" to 26" to see if that may help? Once again guys would really appreciate any feed back or advice as just feel like I'm kinda blagging it as I go, just there's so much info to read out there its unreal and makes it difficult to decide on what's good and whats not, to many conflicting opions it seems.
