I do have environmental issues now in winter(lowest point 14°c) which may make things worse. Especially when my highest temp is 28°c, difference is way to big.I usually try to get all those discolorations worked out before the flip. Youre pretty much there, so you could flip. Id top, prune small lower leads and a lot of the lower scruff off (I prefer bonsai/bush.) And if you have the time : Give them a little "rest" for a couple days(raise light high up and reduce fertigation) then resume veg, once they grow again then flip. IF you dont have the time just flip after prune. It is possible something like this could be caused by a root pathogen.
Adding a heater would solve it but I allready got a 2kw heater w/digital thermostat . Lights and all equip pull about 2k also. Got 2x 25m with cable and a bunch of splitters.Add a little space heater? they are like $30 at hardware store with built in analog thermostat.
Ive been pruning bonsai for years now; prune excessively in veg (not defoliation, just removal of lower scruff and leads) and top all the way up to flip. Prune days 1 and 21 of flower doing same thing minus the topping. If you have extra time you can be removing lower branches all throughout those first 3 weeks of flower. Stop removing lower leads at after day 21. If defoliating most do it at day 1, 21 and 42; sometimes defoliation only at 42 is good, just don't overdo it like most. I get 2lb per plant without CO2 pruning like this in coco dtw.
Wouldn't that add moisture? Or I guess it should work with lids on as well, problem solved. Interesting direction though. Could solve this by adding something to the room that will absorb alot of heat. Thx man, full of ideas!Could add some water buckets, to soak up heat and radiate it at night. Not sure how much this would do though; old greenhouse grower trick... like putting a bunch of large stonesaround plants outdoors (which does raise temp a couple degrees at night) all from thermal energy release stored during the daytime.
Usually around 3-4 months veg from date of cut taken. Could prolly do 2 months if pushed it. Pretty much all vegetation on the lower half of the plant, which will push the growth outward after topping. Then once the canopy is full, smaller leads/shoots/tops that, like in a forest, would only compete and make the other nugs, or trees, smaller should be removed.
