Looking for PETG Tip

[qwiktune]

Monoprice Maker Select v2Temps = 150/7520 mm/s print speed (inital layer speed 8mm/s, only way I could get it to stick properly)Wall speeds 10 outter and 20 innerInfill 80% at 10 mm/sSo as you can see it prints decent until it gets to printing those little pillars. They were thinner in my previous model and thickening them helped a little bit with strength. You can see the layers dont seem to be clean though. I found that dropping the fan speed to like 25% so its still speeding but barely helped a little bit. My question is what is the issue here and what can I do to make it look cleaner like the body of the print. My print is in an enclosure as well. When i print in PLA it turns out good but i've always struggled with PETG.
