Purple urkle CFL grow?

for my first grow I got what it was suppose to be a purple urkle clone a couple of months ago and this is my 8th week of flowering. My concerns are , i dont think its purple urkle because i havent seen any signs of purple coloring, and second, the buds didnt develop as i thought they would. I Lst'd it and put them under a scrog, gave the right nutes and lightning schedulles, but the buds just didnt seem to get bigger, only the main top that is the main growing tip of the plant has a decent size bud.

any suggestions on what could've been the problem? I dont want this to happen to my next grow..

generally purple erkle is a low yeilder of great buds. The purple usually comes in late flowering from what I understand but 8 weeks in IDK. Good luck hope it purps up for you or at least tastes great, all the urkle and hybrids I've had were amazingly tasty.

not all of them turn purple but if it does it will be near harvest.keep the temps cool 70-80 usually turns my purp strain into barney.looking good tho.goodluck
