So I'm on my 3rd grow now and first attempt at feminized seeds vs only autos. I have 2 Durban Poison (left and right) and a Gelato Auto (middle). I wasn't going to do autos this time, but between giving away bud and my wife and I going through almost all of our bud from our last grow, I figured why not. I was planning to start the Gelato indoor and take it outdoor about a week ago. BUT Temps are still too cold at night, plus where we live, we literally can go through all 4 seasons in a week lol. We had a snowfall and 3 days later 80 degrees and now it's just nasty, cold and rainy. Needless to say my plants look good for being fairly new to all of this. This time too im trying to give lighter feedings over time vs heavier feedings with just water in between and i notice my plants looking way better to my previous 2 grows at this time.
So my question is... my tent is only 5' tall and I'm minimally about 40 to 50 days out on my Gelato Auto. I've started topping my Durban Poison to try and get more main stems and fill up my SCROG but I don't forsee me having much room left after another week or 2. If I switch over to a 12/12 light schedule in about 2 weeks, will it fuck up my autos? Any suggestions on how to continue all 3 plants in a 4x2x5 tent? Worse case it's looking like we may get up to consistent Temps soon and I can rake it outdoors. I just love controlling my environment. Any suggestions would be awesome. I'm on day 40 of Durban Poison and day 35 on Gelato Autos.
I'll attach my grow journal too and some pics and videos to get any feed back.
Lastly, for future am I better off with just 1 or 2 from fem plants in this size tent? My first grow I did 6 Grandaddy Purp Autos in 5 gallon pots (I was new and little knowledge on pot sizes). I currently am in 3 gallon mesh pots
