First Grow / Plant #2 / Mystery Strain

Hey friends, end of week 4 from seed :) - I had to transplant plant #2 from a 2 gallon pot to a 5 gallon fabric pot because roots were coming out from the 2 gallon pot, I began noticing some change in the color on leaves so I immediately decided to make the change. - Plant #2 still hasn't revealed its gender to me, I can't figure it out because I see small pistils all around the leafs but there is just one area on the main stem with to very small round balls. I am hoping pistils come out from these balls as it did on other parts of the plant. - Thinking of purchasing a bigger tent, I feel this one will fall short once this plant matures. I might leave it another 1-2 weeks in vegetative stage. - Trimmed some leaves - Performed some LST on plant #2
