Help My big bud x white widow is skinny yellowing slow growth almost 5 weeks in BLOOM

BBxWW is the only one of my plants thats doing this everything else is fine. Im in 2 gallon pot in ff oceaN FOREST AND GH 3 PART but i quit giving nitrogen completly could this be why whole plant is yellowing and buds not growing big.
Is a 2 gallon pot big enough to flower in my plant is bout 3 ft tall wouldn't rootbound plant turn yellow a grow slow?

PICS Coming soon at work right now!

My leaves look kinda like skinny peppers with a light green yellow color

not to familiar with the strains, but sativas ( if there is any in that cross) tend to be bitches and take their good 'ol time. sounds like with your description of the leaves normal to me. pics would do wonders.

more info along with a photo would be nice.

How old are plants, ph, temps humidity the works.

all of my other plants are beautiful even the big bud x ww clone from the plant i have in my hydro setup is doing very good buds are big.My ph is at 6.5 my temps are around 80 and i dont know my humidity the plants are just getting to week 5 of flower under my dual arc 600hps 400mh

the plant is now yellow and getting crunchy Do you think she can recover??

yea she can recover, im growing a white widow now, but its my first time so im not that far on the WW. flush them with 3 gallons of water and let dry for a few days. see if that works and just water once dry. no food, if the leaves are curled down then you need MG (magnesium) which they do a lil bit, i use epsom salt, 2 tabspoons in a gallon, but i would flush and dry first fa at least a week or so. If they curl up then you need magnese

that downward claw like look and glossy appearence indicates to much nitrogen, and the twisted looking leaves tell me your PH is off, or your temps. are to high.

check PH and and flush with neutral water.

I agree with Gobskii. You are feeding your plants to death. Back off the Nuts.
