believe me, I know what you are taking about. It took me quite a long time to study and improve as well. No, this does not mean you should quit - that is not the american spirit I know
I think what you are lacking is mostly theoretical knowledge - i.e more reading. I will even say what I don't usually say and refer you to grow guides - as simplistic, way too general yet way too specific as they may be. You may have already watched read a few - but (and i'm totally not saying this to diss you) - it looks like you weren't really paying attention in class
you're lacking the basic knowledge of how plants work and what it takes to make them work artificially as we try to make them.
for example - a very basic thing (one must admit, not many growers are aware of) - is that, assuming you don't feed your plants with straight minerals but use a nutrient formula like everyone else, then giving more food to a hungry plant only makes things worse. A hungry plant is hungry not because the soil lacks food, but rather because there are chemical conditions in the soil that prevent it from eating the food. Either the formula is inappropriate (not well balanced for the plants needs), or what's more common - pH is off / too much nutrients / salt accumulation from too much nutrients over a long period. It sounds complicated but there are simple steps to counter this in 90% of the cases - flush well, start feeding better, allowing runoff, if needed changing soil and better of all - switching to coco.
As for other issues like ventilation, light etc., all I can tell you is you should learn some more (and implement) the necessities, this is a simpler matter, all you have to do is keep those temps below 30 anyway you can. extraction to outside is important, as well as intake sometimes. If using an HID, a cooltube (100$ for new) will do the trick.
And yes your genetics is excellent, it's probably just a bad seed in a batch or something, this happens with most bought seeds, bad luck, but getting more expensive seeds is said to reduce this risk (I can't say from my experience yet). One thing's for sure - when growing only one plant, you wanna do the best you can to ensure it's got good genetics. This one for instance, despite all it's been through, I don't think putting on so little resin is only due to the stress - I think it's bad genetics that contributed. I've seen this happening. just a phenotype.
I can't give you advice about the light unless you tell me what and how many lights you're using
but in general - CFLs are good for compact plants only. Bushy indicas is best (kush is supposed to be ind., but this one is very sativa-like with its stature). In any case, proper training (as well as short vegging time, preferable 12/12 from seed/clone) is required to keep the plant as compact as possible, then you want to place those CFLs really an inch or two surrounding the plant so it upper parts at least get similar levels of light (more light more bud naturally). With HID's and LED's training is also required (in general, the shape of your plant is only good for outdoor plants. no indoor grower should let a plant grow like this), but allows for more freedom and much more plant size. Height is still bad, in any case.
You WILL get a nice smoke and some 15-20 grams off this lady, but it won't be anywhere near as good as 20g of properly grown weed, and it will deplete much faster (less resin on buds = more bud in the joint).
