Just remember, any leaves you remove will just reduce the plants capacity to make energy, and on a plant this small, a leaf or two is a big percentage of available energy making leaf cover.
You also need to invest in some dedicated cannabis nutrients, Miracle Grow is ok for Grannys' garden, but not for top quality buds. They will taste very metallic and not pleasant at all.
Yes, now that it is too late and you have attacked her with the scissors, waiting a week or two until normal growth resumes is wise if you intend potting her up into a larger one. The roots coming out is a normal feature with air/rocket pots, the roots will "air prune", which is a nice way of saying "shrivel up and die" and is exactly how air/rocket pots work.
Seeing as this is a photoperiod strain, she will need a much bigger pot to sustain her through veg and flowering, something in the region of 4-10 gallons would be more appropriate, depending on your space availability.
You also need to disconnect your "dripper system", it is far better to water deeply and until run off every few days than it is to have a constantly (over) moist substrate, which can lead to fungal problems and the death of your plant.
A thorough watering, then wait until the top 1-2 inches of the soil have dried out before watering again is the usual routine applied to soil grow cannabis. This "drying out" between waterings can take from 1-10 days, depending on temps, soil structure, plant size etc.
If space is freely available, just planting the whole rocket pot inside a larger pot can work, the roots will grow through the holes and into the new pot surrounding it, just be sure to pack some soil against the smaller pot so there is no "jump" from the small pot and into the larger pots that the roots will have to make. I have done this previously with air/rocket pots, however I have buried them in the garden and the plants grow as if there is nothing weird going on.
I have also placed smaller air/rocket pots on top of larger ones to create "double decker" pots and as long as you make sure there is soil contact between upper and lower pots, the roots from the top pot will grow down into the lower pot without even thinking about it.
If trying this technique, just be sure to carefully "attach" the upper pot to the lower pot with string/wire/pegs etc to prevent the top pot falling off.
As they say, there are many ways to flip a flapjack!
Both of these methods help avoid "transplant shock", but if you are careful and have everything prepared prior to starting, unwrapping the air/rocket pot from the root ball is fairly straight forward, just be sure to not have the soil too wet, otherwise there is a high likelihood of some of the soil falling off the root ball, causing damage to the roots and "shock" to your plant that can delay recovery for 1-2 weeks.
Hope this helps, Organoman.
