easy rep! estimated time and weight. pics!

i just got a couplse pics of my plants, they are 4 weeks into flowering. i am wondering how much i should be expecting to yield, and how long til harvest. i can make a pretty good estimation, but would like an opinion from one of the many experts on RIU.

i am currently using fox farms ocean forests soil and tiger bloom bloom booster, with organic sugar.

on my aerogarden plant i have 2 42 watts,

on my 2 soil plants i am sharing 2 300's, 4 23's, and a 13 or 2.

i was expecting at least a ounce per plant, but with harvest time approaching i am getting a little worried. all help is appreciated and ill rep it up. all day son

It's hard to tell this early, but they look a little underdeveloped for 4 weeks 12/12.

6-8 weeks till harvest, I never guess yield as if I did I would base it on my capabilities which wondered be fair!lol

id say 5 weeks minimum there looking a little underdeveloped but nothin that cant be sorted as for weight how longs a peice of string

this is my great white at about 4.5 weeks flowering. under mostly sunlight from the windows and cfls. just remember they lose about 70% of thier wieght when drying. it is kindof crazy how much smaller the fluffier buds can get. keep growing guy

looks like 6-8 weeks left maybe 1.5- 2oz dried

I'd say 6 weeks from the pic. It's hard to tell what you will harvest this early like Stoneded Mentioned but If I had to guess now would say any were between half ounce and 1.5 ounces.
