Are these girls just hungry ?

[Snafu34]

Good Evening ------ I could use an opinion or two please. The large fan leaves on these two girls started turning yellow a couple days ago. A few that are solid yellow and need to be plucked. The new growth is a nice shade of green and appears healthy. 4 weeks into flower- fairly fast strain. Are they just hungry or ?
2 gallon pots - Fox Farm ocean forest w/perlite- 150w CMH- G.H. Maxibloom - 3/4 to 1 tsp gal. every other watering 2-4 days apart. Temps- 63 to 82 60% humidity.

THX for looking-

I'd say hungry. Did you ever use the Maxigrow in the veg stage?

THX Guys- I did use some Maxigrow but may have switched to Bloom too early. When I first spotted the yellowing I gave them a little extra Bloom
for two feeding. I am a little leery of over doing the N at this point- Any suggestions ?

are you adding any epsom salts? i use mg and mb also and have found epsom salts helps

No I had not - I have feed twice in the last week - 80% of older/large fan leaves are golden yellow - buds keep growing but still not how it should be.
