HELP pronto! yellowing

2 out of 3 of my girls are yellowing
i just recently started feeding them nutes about 2-3weeks ago had zero burns
until now and now getting some mad yellowing
the one on the far right with no yellow is an indica that seems to be damn strong

medium: garden ville potting soil mix 50% w/ FFOF 50% w/ bat guano and worm castings as well
under a 4.5ft t5 6bulb
temp around 80oF normally

do they need a flush or what?
and how?
they are in 5gal buckets

Tell us how much and what you fed, and your watering habits.

i wouldnt say they need a flush but i wouldnt go adding anymore nutes...bat guano and FFoF is some good organics and should be keeping them plants well few past thier veg cycle...if yellowing increases without adding more ferts then yes flush and leave em the hell alone untill they say "hey feed me fucker"

just a word of advice, if you think that is mad yellowing your going to go nuts if you let them get worse,

i'd agree though, ease off on the nutes, but also by the compactness of your plant i'd say some of the bottom leaves might be dying off themselves to make way for more efficient leaves further up the plant, as they dont get enough light for it to be worth sustaining

I would just water with ph regulated water. The soil has enough nutes usually to last about a month.

okay thanks the nutes that originally started were was organic sea tea from garden ville and i even asked the person running the shop if i should dilute it more, but watering cycle is only a couple times a week; fully saturate the soil, then let it dry out

Nute overdose.

Just use PH correct water a couple times.

Soil usually has enough nutes for a couple of weeks of decent veg growth.
