well. guys. thanks for all the helpful information. and just to clear something up... the 4 pictures i uploaded were TEN WEEKS OLD!!!!!!!!!! the sativa pictured in the front left is still growing. Monday, January 12th will be its 12th week of 12/12 lighting and it is no where near being finished budding. she still has 80-85% white hairs on the buds.
the two plants on the right (the ones that look like a strong indica mix) finished their flowering 4-5 weeks ago. yielded about 40 grams off the two plants. (1.5 ft tall)
the plant that you can't really see thats in the back left finished its flowering 3 weeks ago. it was a sativa/indica mix. I tested the smoke out yesterday and it was good, really good. i'm quite impressed with myself... although it only yielded 20 grams from a 3 foot tall plant
again. i haven't used any nutes. I don't know where to find any good ones.
after reading all the posts it seems that an investment into nutrients seems to be the most logical choice. I'll do some research on proper nutrient mixes and i'll come back with some newer pictures later on.
