You gota work with what you got, thats for sure. When you can afford to spend some money on it later be sure to spend it as wisely as possible and you will do just fine. Its quite a nice little "ghetto" thing you got going, reminds me of the old days rofl.. Actually if you showed me those photos when I was 20 I would have been big time jelouse and begging for a bud! HAHA.
Its a small room, only 400w growing in dirt, low budget, no co2, with no veg cycle at all, quite impressive so far if you ask me. Oh and I have to agree that your photography does indeed suck hahaha, however even without the greatest pictures/camera its easy enough to see how green your thumb is.
In my 40's and was 19 or 20 for my first "real" grow, I had done the ghetto thing to start seed and planted outdoors when I was younger than that but the results wernt the greatest. Atleast 8 of those years were hydro crop of some sort and no I havent been growing constantly from that age but pretty close. As for your final question.... BORN AND BREAD!
Now I have a few questions....
How old are you?
What neuts are you useing?
Any idea of the PPM or EC of your soil? or an idea of how heavy a feed your giving.
Useing tap water?
Could you please describe the total setup again and include a basic run down of how/what your general care practice is from seedling to harvest?
Do you have to take a growing break or can you squeeze one more in there?
