I think the bud development rate is such that, although I probably hurt my overall yield, they'll still make it to harvest with a decent amount.
As it is, I'm only growing for myself, so anything more than a couple ounces is more than enough.. and I still have 3 OG Kush clones to flower when the first 3 plants are done.
I'm thinking another 2-3 weeks and they'll be ready for harvest.
I gave em half a dose of liquid kelp and half a dose of golden tree with their 2nd watering since the last top dressing. I'm proceeding cautiously for the rest of the grow.. as it is, their in week 7.
