Should I replant?

Hi,

First time trying this little hobby experiment and I was hoping I could get help from someone with some experience. I'm not sure if my pots are too small and I should replant to something bigger. Here are some facts (not sure what you'll need so I threw it all done there):

The pots are 9.5 inches high with a 10 inches across the top. I've got gravel for drainage in the bottom of them. (Ignore the middle one. I just started that and will move to another closet soon).
The plants sprouted from the soil almost a month ago.
The strain is Northern Lights
The PH is slightly higher than 7. I'm giving 'em some plant food slowly to try and lower that a tad.
The lights are Daylight Fluorescent bulbs (150W equivalent) and the top of the plant is getting about 2000 Lumens.
The temperature is around 70-72 and the humidity is around 40%

Would I being doing them more harm than good by transplanting?

Thanks for the guidance.

your pots should be fine. there has been much debate, and I expect there will be numerous opinions that you receive...some contradictory I suspect......but depending on your individual circumstances, space, height, lights, etc. you can use plant even down to 500ml if you are so inclined.....that seems to be a threshold. I have gone from 20l (5gal) to 2gal to one gal........thats still 4.5l and I think thats as small as I will go.....but then I could be wrong?

Thanks for the input. 'preciate it. Looks like they'll be staying put.

no worries...these sorts of decisions are all a measure of benefit and risk....you measure, you gauge, you weigh your priorities and objectives...then you make a decision....and watch what happens. good luck!
