I haven't read through the whole thread, but I didn't see any pics. Are you sure it's the strain? Not trying to offend anybody (I know we all tale pride in our growing swagger) but I'm on my second grow, have only popped 3 strains (other than bag seed) and the difference between them and the bag seed is UNBELIEVABLE. With one exception, I grew a seed from a dime of Mexican shwag that wound up yielding ten ounces, and was a sativa pheno. The potency wasn't the best, but I was greatful for the yield.
But yeah, I've grown white widow from g-13 labs and bubba kush from hso on my first run; the white widow was so-so but the bubba kush was AMAZING. Super frosty, super powerful couch lock stone. I'm growing out an OG kush from hso in my second run, and the results speak for themselves.
If I were you I would try switching some things up. You seem to have a good knowledge base (again, only read the first post but you said youve been growing a while). Maybe I've just been lucky, but I can't imagine going through 35 paid seeds and only catching 4 that were worth a shit.
