Is this normal? Using Cybs tek.

Also is it must to re-x if i make changa? Spice is mix of yellowish goo, yellow spice, white spice and light brownish spice.

Only you will know if you followed Cyb's tek to the letter. If you did and were careful to avoid lye contamination which you would have noticed, then your spice needs no further treatment. The colour or consistency is irrelevant; from white crystal to golden yellow to red goo...all is good. My personal favourite is golden spice so I do my pulls hot. Work clean and no re-ex is necessary and could result in loss of yield.

I agree with Fidelsbeard. If you don't think you pulled any of the base mixture I think you'll be good to go. And to me it doesn't look like you did, it would look like much darker spots. My first extraction with chacruna was quite yellow, but I knew I did my work well. It smelled like I had heard it described and otherwise looked like small, powdery crystals. It smoked well, no regrets.
