Auto Reek'n First grow ever

Since I didnt know about this site before, I only just now am able to start telling yall about my experience. Thing is, we germinated the seeds 3/07/18, but because of issues with the delivery of the tent and lights, were only able to put em on schedule by 23/07/18, which I am counting as around 1 or 2 weeks in stead of 3, is that smart for calculation? I give 4 liters every 3-4 days. Am growing 2 plants, one of which boomed up to 75 cm while the other one is 50 cm my tent is 1,80 in height and 1m². They started showing flowering signs a little more than a week ago, so we started giving bloom nutes then (27/08/18) other than some heatstress marks on SOME of the biggest leaves in the past we've had no deficiencies (keep in mind we dont ph or anything) we defoliated quite a lot,but that was necessary. The smallest one (ID'd Virginia) is showing the biggest preflowers, while stthe biggest (ID'd Stretch) is showing a little less, but thats also to do with the height I think, both autoflowered tho, so Im happy pics following
