AW critical purple

so up to this point the plant has been topped, (10 days ago), and have tied down the 2 dominant branches. If this plant follows the same growth pattern as her 2 indoor sisters did, there should still be more than enough time to tie down twice more before entering flowering stage. I feel like a little growth potential was lost over the last week because of no sunshine. Actual height would have been about 13 inches but 4 inches were bent horizontally for LST. Only rain water was provided over the last 10 days. Plan to introduce 1/4 strength nutrients starting next week.
