I have gone 24/0 20/4 and 12 / 12. They were all awesome grows but they all had to be treated differently .after several auto grows I have learned they will get as big as you want them to get or as big as you allow them to get. I am on my 48th day, i'm taking down this 3 x 3 tent with a 600 today and leaving them in the closet and upping it to 1000 watts.
I am using the new Sensi pH perfect formula. I am just using the base.
autos CAN and should be stunted on purpose but not until you have experience with autos. I recommend everyone growing their first few autos with the K I SSmethod (low low ppms ) . If they are transplanted prior to stretch they won't stretch and still produce big buds. notice my center auto with the cigarette pack was purposely stunted as I want it to be behind schedule. last year you will notice 4 jock whores produced Over a gram A watt Of stank stank. I was going to keep them in a tent but I guarantee you since this is early flowering and this 3 x 3 is full,if I put 1000 over it and space them apart more they will continue to get bigger these are big and just started flowering. I use 5 gallon smart pots 100% coco Galaxy ballast. First time using AN ph perfect . I will get a picture of the one plant I did not want to stretch I made it like I will get a picture of the one plant I did not want to stretch I made it like this on purpose notice how thick the stock is on purpose notice how thick the stalk is. are there any other advanced nutrients products that would help with flavor etc. I was going to use molasses The last couple weeks
