Zkittlez Auto (My first grow)

It didn’t go as I expected, the plants are slow growing so i think they need more time maybe 2 more weeks (until week 12) for them to be ready for harvest. Due to change of timeline i did continue my feeding and increase a little in the nutes, maybe this week will be last feeding before flushing. I defoliated all three of them, I cleared the bottom part and remove majority of big fan leaves. I remove LST on my two plants but one plant still continues.
