Nice Baby :)
Be careful with Nuts bro, see smaaal yellow tips on fans, that's a sign of a nuts burn.
Took a look at your Grow Big nutrient - it is very hard to play with it's dosages in different stages (veg/bloom) as it has almost identical "N" and "P" like 6/4 (NO3 and P2O5), but converted to pure like 1,4/1,8 with 3.3 K (which is ok, I think).
Good luck bro!
