Big Devil XXL microcultivo

First os all, sorry cause I didn't photograph plants before I did LST them. They have started preflowering with that little size. I do still expect them to stretch up to 2 or 3 times their actual size. They have kept little probably cause I have not been controlling PH properly but adding a little citric acid (without measuring final PH). I'm also using a 3rd generation recycled substrate with a mix of sand, homemade wormcastings, perlite, vermiculite and a bit of bat guano. I'm also not controlling humidity, wich has been at around 40% (low for vegetative stage). I have also not watered enough due to work travels. So after all, they are growing great for the conditions on which they have been. ----------- I have done a hard LST on both looking for a kind of SCROG effect on my tiny 40x50 wardrobe. There are photos of already done LST and 10 hours later. During the process I broke a back branch, a pity but not a real problem. Node distance is also too small as I left the light a bit too close, so I have now separated it a bit so buds will grow a bit more spaced. ------- In conclusion, unaware growth, good looking plants.
