What is this

[907guy]

I noticed these white hard things on the stems,,I've also found 3 red ones as well,going into 3 weeks of flowering,week 2 iswhen I started seeing them.as of now I've been just taking them off with my fingers,three different strains,,soil medium, 2 600 watt HPS,and a 300 led! Looking for insight into what they might be and a cure! Thanks

I can't see what you are asking about.
If they are underneath a bud site - it is probably a caylyx.

Just a quick look in the plant problems section and I found this. Hope it's something else though.

Not positive but I found a few things searching around for ya. The fact that u saw some red ones looks like they might b resin or sap bursting out saw o few things saying that. If u rub it off and its oily and skunky then that's the deal didn't look like a bad thing but also look into the above post on scale. Hope it helps and good luck to you
