Hello! What an exciting growth to watch.thru-out hopefully my first grow to turn out alright. On Day 40-41 I spotted a few bottom leaves turn a bit light green on Day 42 it was a bit obvious here and there thru out the pots. Especially on Girl Scout Cookies pot. On my next water Day42, I upped call mag from 0.5ml to 0.9 for correction with the Bio-Bizz guideline. Let wait and see in the coming few days! Also, I alternate between Fish-Mix and Bio-Grow every watering not sure if it's alright but the plants respond well with the feeding. Check out my small pot some good-looking buds come out of the small pot. And for the last two weeks I've been defoliate here and there too. Mostly on the lower bud sites and big fan leaf on the top that covers bud sites. I did it every 2-3 Days mostly I do the adjustment for LST before watering together with minor defoliate. But somehow they still look thick. but at least most of the bud sites receive most of the light. Any thought on this with the picture above does it look alright? Cheers and happy growing!
