First Time Growing

I’ve decided to add my other 2 cream caramels to the grow. Was only going to record one but going to do all 3 now. The fabric pot was planted one week later and is stretching a lot. Have topped this one and one more of the girls as it was blocking a lot of the plant. Also cut a lot of big leaves off hoping it doesn’t stress it too much. Have also incorporated a diy co2 system to give the plants a boost. Also run off ph is a lot higher the inflow hence why I dropped my inflow ph and one else noticed this? Although run off ec has been a lot lower then inflow so guess they are eating !
