I'm currently growing three Autos, two White Widows and a Durban Poison.
I do the WW's in an NFT tub and Lil' Durban in soil, well really mostly green waste compost.
I topped or FIM'd all of them and they are 9-10 weeks from seed now. IDK if topping the WW's changed their structure as they appear to be different phenotypes. WW#1 is now ~36" and WW#2 is barley topping 21". WW# is frosty and stacking her buds, WW#2 is greasy and has buds all the way below the SCROG net. I've been driving them hard and keeping PH 5.6-6.5. They really haven't taken that much GH Trio maybe 2 oz each for the 10 weeks. WW#1 has had full spectrum light at as much as I could give her with my 100 or 150 watt lights. Keeping the lights close untill the plants spread out.
I doubt that I stunted WW#2 with the topping at node four but she's got 10-12 colas from mostly a ~80 watt Burple. She's sticky and frosty. I won't get much off her as she's small, but that's the ruderalis I guess.
WW#1 is certainly not stunted! SHe filed her half of the SCROG Net and is pushing #2 out of her's! I think she's stopped stretching now at ~36" she tried to hog a bit of Lil' Durban's light too. I cut her back though. She's got top all over at least 12-15 colas formed and frosty.
Lil' Durban has had a rough start, but is now pretty happy. I tried to FIM her for four top colas but missed and got only two. she's filling out now and hairy as heck. She has a very light color almost lime green and I've been feeding high N Trio mix at full strength. The soil is very moisture retentive so It's not something that feeds nutes easy.
All in all I kinda like my Autos, but I think I can get off on these girls after new years. I do think that autos can have a lot different pheotypes even from the same package. I'd like to get any one of them in a uniform pheno package. But cheap seeds from Spain that isn't going to happen.
