Winter mini grow auto blueberry

**** Wed 01 Jan 2020 **** New week and a new year. Got a bit of yellowing on some leaves - this roughly corresponds to when I was adding 7-7-7 feed This is much more apparent on the "Black" plant on the left, which had a big growth spurt at this time For now they are on plain water at PH 7 They are still on 24 hour light - apparently this can add to nutrient burn too I do have some PH Down (Phosphoric acid 25%) so wondering if I should try dropping the PH a bit All the same, the buds seem to be building up **** Thu 2 Jan **** Yellowing doesn't seem to be getting any worse, and the main buds are slowly getting bigger and frostier Some of the lower buds don't look bad either Should I defoliate a little to get more light to the buds? **** Sat 4 Jan 2020 - day 53 from seed **** Despite my best efforts to kill them off, these two brave girls insist on growing See today's pics - "Black" on the right keeps getting bigger - "Red" is just all bud underneath Can really see how the yellowing (nitrogen tox?) has affected one plant more than the other So glad I didn't just do one plant Have to give these girls some respect! **** Sun 5 Jan - day 54 **** Buds slowly getting frostier They've been flushed and on plain water for almost a week I suspect my initial soil (clover compost) was a bit rich + transplanting + low humidity + tiny amounts of 7-7-7 = stunted plants Keen to get these finished and start over **** Mon 6 Jan - day 55 **** Must confess I snipped off a popcorn bud from Red the other day - this was right down by the base root and was never going to see any light Bud was tiny, just a few pistils and very few trichomes Dried for 24 hours in a tin on a radiator, wasn't expecting much, smelled like damp hay Actually tasted pretty good - like grass used to years ago Damned stuff is ridiculously strong - head buzzing all night - could hardly get to sleep Very surprised! Posted a couple of pics of main buds - there are lots of side buds too Red is definitely further along, but Black is going to out produce her Apart from the yellow tips they seem fine Now curious as to how they'll do over the next 2 weeks **** Tue 7 Jan - day 56 **** If you compare today's pic with a week ago, there's just a little growth Buds do seem to be fattening up though Interesting how the "Black" plant is much more affected by yellowing than "Red" That's week 8 done lets see what happens next week
