Wtf ??

what size pots, what was your temps, and i personally dont have xp with theses nutes. If they are salts id lok into more tried and true boosters, if your running organic, well ya the yeild isnt going to be threw the roof. Again what size pots and was your canopy adequate tothe lighting or were you wasting space?
Happy farmin;)

Look like ya need to fill up more space to get a better yield nice looking buds though

You don't need supplemental Co2, nor a mini-split to have a healthy, high yielding garden.

We need more info about your environment to provide you with better input - day/night temps/humidity etc. Pot size. How much and how often were you feeding?

From seed or clone?

If this was your first grow, be happy it was at least successful in the fact that you produced some flowers - now it's time to fine tune :)

Not my first grow, my third run of indoor. I had an 8 inch fan always pulling air out of the room, Humidity was around 20% the temp during the day was around 80-90 and down to 60 at night. The canopy was proper and they stayed in 3 gallon pots. Not root bound.
