Outdoor indica unknown strain

I'm beginning to start getting sad was for sure by now we would see good buds but she still has her tops closes!! I'm getting frustrated I mean she is almost 20 wks old. She better get it together !! If any one has any ideas on what to do I'd love it! We are feeding twice a week started adding big bloom too! She taking it like a champ! But the buds!! 7/19 today we moved the green house so the plant had more growing room. It was literally taking the whole place up. Now its gunna grow great! Where her tops were touching the house it burnt her bad bunch of leaves burnt 1 top pretty bad. It's hot here and I couldn't watch her die after every thing I put into her! She is over 6ft tall nothing holding her down now she gets all she can get!! Happy growing everyone and happy summer!!
