400w Pineapple Express, Bubbleicious, Northern Lights

Hi, so currently I have a 400w grow 3 are Pineapple Express and the other 2 are the bubbleicious and NL It's about week 3 of flowering and so far so good, well Kinda the bubbleicious is losing a lot of leaves and i'm thinking its potassium deficiency. But i'm no pro and this is my first legit grow, I'm using foxfarm ocean forest in 3 gal. pots and using FF Tiger Bloom and the temps are 80-82

Please help :O

Looks like a nitrogen deficiency. Are you using the Big Bloom along with the Tiger Bloom as per FF feeding schedule?

I am not :/
I was thinking it might've been nutrient lock

Doesn't nute lock come from bad water pH or too many dissolved solids? If you haven't changed your water recently that shouldn't be an issue. However I'm pretty newb so not too sure.

well I just fill up jugs full of water and leave the lid off for the day so all the chlorine can dispurse, but last time I checked the pH was 6.5 or so, so I really dont know. MORE HELP PLEASE

Yeah, I'm not too sure, but here's a bump.

I would check the ph again, I'm no pro by any means but I would say get the ph right "for sure." Then look into nute deficency.. If you look at the Fox farm site for soil, they recommend adding "grow big" durning the 7th and 8th week of flower I think it was, I'm assuming its for the simple reason that the plant hasn't been getting much N from the "bloom" and "flower" nutes.. Just my .2 cents. Good luck! I want to know how that pineapple express turns out

did you say bub bubbleicious...lower ur ph and adjust your nutes ,give it a small amount of of veg nutes..this plant likes to be finicky with nutes one day it will show signs of burn and the next it the little shop of horros allways sayin feed meeeee....i got this in hydro and at the end of flowering a few leaves die but the bud production continues....

will do guys, thanks for all the input

lol anyone know if lollipopping technique works good?
cuz it seems like thats where its going
