First Grow - need help (pics)

Unfortunately, i don't have the right tools to mesure PH level.
my next grow is going to be Hidro, and with that investment i will buy the PH meter.
Any way, my babies look real good - i just FIMed the top of the plant and i'm becoming impatience so i decided that two weeks from now - i will start flowering.

yes! get something to test PH! I bought this great product at the hydro store (can't remember the name) you put a pinch of soil in it, put the powder from a capsule in it, add water, shake and it will turn color and you just match it up to the chart....I love it
