Balcony Grow Shiva Skunk

Bili_R started with 20 bag seeds of some shiva skunk i got 3 years ago.. managed to fuck it up, let them soak too long, almost all germinated, but only 2 survived with root problems from the start in bad soil. one of them started a mutation, 3 sets of leaves instead of 2. after about 10 days I got a 17W LED for them for the first few weeks indoors. also had a lockout problem due to bad water... so I removed most of the old soil, repotted into good soil and bigger 0.5l cups. They recovered just fine. after 3 weeks or so, I repotted into 3.5l pots, and a few days ago into 6l pots.. I put them outdoors the last 2 weeks when temperatures got warm enough at daytime. I supplemented with LED in the evening to extend daytime pretty unregularly. both showed sex after about 4 weeks, both female so far... they already got lots of sun. I have just above 15 hours of daylight right now, so I hope they won't start to flower already... night temps are about 9 degrees C , so I leave them outdoors from now on. Day temps about 15-25. I plan on topping at some point too, as I am trying to keep them small. Genetics are NL and Skunk so I guess they will stay smaller anyway.
