Hi.
I'm not an expert, but to me it seems you were overwatering at the begin (water too often, leave the roots wet and not just moist for too long).
The curling up on the border of the leaves mean the air is too dry and you think she need more water. But you do not compensete watering more, on the contrary, you increase the difference between the air and the ground (research: "water pressure in plants"). In this case the suggestion are: buy a humidifier (do not know your climate, it may be that you will need also to dry the air in other season, but this is another topic....) or use a "temporary" fix with water towel like you did or spray water on the leaves. It is possible you have a wrong air setup, too much air exchange with the "outside" of the growbox. It's important to move the air inside the growbox, but the exchange with the outside is needed mostly to provide enough C02 to the plant and overdoing it, can cause climate problems inside...
The yellowing seems a zinc deficiency that you thought it was nutrient deficiency and you fertilize it (giving nutrient burn).
But nutrient were already available in the ground but not to the plant because of the overwatering.
Happy growing 😉
This is a KILLER looking grow. I see some experience shining through here. Nice job! I see we are both utilizing the 24/0 light schedule with our autoflowers. Not many of us do this beginning to end of grow. I am attempting my first "topless" SCROG (trying to bend instead) with 6 different strains right now. It would be cool if you would like/follow along and make a suggestion or two. - Zannabis7
@Zannabis7, its a good smoke man, for sure it is, the buds are not much compact, i would like to remember i used only biologic feeds in minimal concentrations, so its more like a natural plant then a pumped up mutant, and the result is in the taste which is really clean and fruity. no headache
@biggreens420, this week is the last with 24h schedule, as i will have time issues because i added Photoperiod plants in the tent, Will 100% return to this in the next generation of Haze/Blueberry. Will upgrade the next year to a second LED, to make a separate 24h schedule tent
@biggreens420,
It´s my second grow, my first one was outdoor, now i tryed the same seed indoor. Going to push her to the limits in terms of light to tryout
