You had a shit yield because you didn't get the nitrogen out and should have left them growing in flower for 80 days and 4 plants is too little you need 16 or 25 or 64 at day 60 instead of cropping flush for 20 days and then cut them down when it looks dead or drained of energy or completely yellow a lot of you growers trying to save money just waste it because they lack EXPERIANCe
FYI you should do a
sea of green just get
roots organics soil and do 36 2gallon pots and veg for 2 weeks and keep all plants trimmed to about 11 inches then flower they will make many bud sites in the first week of flower
If you just want weed buy it don't waste your time harvesting premature buds you gotta wait like85 days for a good indica to be stronger ouch it will keep you high for 5 hours it's worth the wait unless you got 80 flowering plants don't harvest before 76 days with indica and satovas do 90 or 100 or longer basically with many sativas 130 day flowered buds get red And last like 7 hours don't ever harvest early because that's what comercial weed is
You should buy a digi microscope to check if resin is ruby red or amber or cloudy
You want to grow like 12 to 98 plants in a 4x4 thebest would be 56 or 64 1 gallon plants on a drip system so you can just drip fresh water the last 2 or 3 weeks
