White scum that looks like mucus!!!

I have a plant that is two weeks into 12/12. She is in a 2 gallon soiled pot. I have a t5 light that puts out over 50,000 lumens and in is in a 3x3x7 grow tent. Well to the problem. Today after I watered my plant I noticed a white scum like mucus floating atop of the soil. I have researched this all over the internet called the 2 hydro stores by me and no one can help me out!!! It literally looks like someone hacked up the biggest loogie and spit in my soil... My plant looks nice n healthy. 3wks veg then bam 12/12. Any opinions on the scum or my baby???

I cant really help you on the mucus part of this... But why is your plant only shooting out sets of three? I have never seen a cannabis plant only shoot out sets of three. I have only seen the second set have 3 and 5 for the next 7 for the next so on and so on. Sorry I could not help. You deffinatly do have a deficiency I can see it in a few leaves but not all.

Might be larvae from a critter of some kind

my n lights big bud cross bout a foot and a half tall bushy healthy happy, flowering away (almost 2 weeks 12/12) and it has 3 and 4 prongs only. i thought it was a genetic thing, all my other plants are in identical mediums and have been treated identically and dont show any signs of this trait, i'm not the most experienced grower by a long shot but the leaves only real importance is for photosynthesis and the number of prongs doesn't impede it, i know the leaves are barometers to a plants health but i thought they looked fine health wise

Oh no I wasn't saying any thing about health wise. The gal looks as healthy as could be. It is just strange that it is only still shooting out sets of three.

You got hydro and soil? That something I would do! I don't see what your talking about?
I do see all you plants are stretched! You could use more light! Wtf I can see it's in soil why not tell me what kind?
You have some type nutrient imbalance those 3 finger leave are what I'd call deform or retarded!
