ZkittleZOG Auto Greenhouse Barney's Farm

She is a big girl - almost as wide as tall - circa 1m - two doses of seaweed (10g each time) and one final Vitax Q4 (7.5g) - also gave her a mini flush after the Vitax just to push remnants of previous feeding - starting to put on bud weight - I think I can continue to feed for another week (am on day 57) - before two week flush - target is 70-77 from Barney's Farm but I am unsure if I am on track or not - will keep checking pistil and trichome development - if an auto gets big is it worth waiting a week - or because it is an auto, the alarm clock is not able to be adjusted - first ever grow and so am a little clueless on the timing side of things.. certainly doesn't look ripe yet - but how much bud weight is usually added in the flushing stage?
