Plants have yellowing leaves throughout

Just so you know, I'm at about the same "grow" experience as you, maybe 7 grows or so, and I've experienced what you are now to one degree or another in almost all my grows, currently I'm going through an almost identical experience judging from you pics. Right now I'm leaning towards watering/aeration problems actually.

Hello, I'm new to this forum so wasn't really sure where to post this. Currently I'm on my 5th grow and I seem to be having the same or at least a similar problem each time, around the last week of veg (I veg for about 5-6 weeks) I started noticing some discoloration in the leaves I let it go thinking maybe they just needed to be fed more, I am now on my 4th week of flowering and my plants are basically almost entirely yellow the leaves around the bud sites are still green but thats about it. I'm in soil so my Ph usually sits between 6.0-6.5, I feed once a week with Foxfarm trio nute line at .5 tsp except the big bloom thats at 2 tsp as well as the big swell and molasses at .5 tsp and give them regular water with Hygrozyme and H2O2 once a week. Temps around 80 and humidity around 52%. Can anyone tell me whats going on?

Grow info:
Foxfarm trio nute line
Soul Big Swell
H2O2
Hygrozyme
Grandma's Molasses
Happy frog soil
3 gallon pots
G8-900 LED
Mars II 1600 LED

different strains react differently, looks like you cut the N off a little early for this strain, the buds still look nice though.
i run the "grow" part of my nutes at half strength about 3 weeks longer than the manufacturer says to, if i follow their instructions i get the same thing you're getting, with half strength the extra 3 weeks my fans stay nice and green much longer

Now its not enough nutes....I was told to stop feeding them from previous people. temps usually between 80-85.
I told you in previous posts to follow the feeding chart. The only diff in the chart for indoors, is that you feed 1x a wk not 2x (thats for outdoor) at full strength. Always feed full stregnth, if you get a lil tip burn then you back it off a bit. Id rather have a little tip burn and know that Im pushing my plants hard then have a domino effect of deficiencies from lack of nutes. Follow the chart and you will have awesome results. I think youre running hotter then you think at this stage

So you mean like the pot being too small? Cause I think I've come to the conclusion that my lights are too powerful and the roots are running out of space so there becoming root bound, there only in 3 gal pots and I noticed my last grow there was no dirt...just roots.

theres actually 2 different strains in there, the one strain the leaves are probably less crunchy and more yellow where as the other strain is more crunchy and less yellow at this point.

Your the only person on this whole forum that has said that its not the FF, question whats the ppm of your tap water? or are you using RO?

So its been about 3 days or so and the plants appear to have gotten worse after giving them the Epsom salt on wednesday, I only did about a tsp per gallon but heres a picture of what most of the leaves look like now. View attachment 3727914 View attachment 3727915
i think u have a lock out of nutrients, i will flush my plants really good and in the last gallon use a complete npk fertilizer at half strength with one tablespoon of epson salt, of course ph'd at 6.2-6.5

I have shit water, it fluctuates. Sitting at 200 ppm atm(has hit 500+ at times). I just moved to a new well thats been giving me some shit. Took me a cpl mths to dial in this flux water. I started organic on both indoor and outdoor. The indoor had some issues going organic and uptaking nutes. So on my indoor I went back to FF, bc I know the line very well and it can fix issues pretty quickly. FF likes pure water and adding a cal mag supplement. Its really as simple as that. Ive always had huge buds and great yields with it. Only reason I went organic is to see and taste the difference. Ill know in Nov. When the outdoor is ready.

I was thinking of going organic myself for that same reason so I'm curious to see how it turns out, let me know for sure. I think your probably right, I've decided to upgrade pot size (5-7 gal), not to feed them for the first 3-4 weeks since I am using happy frog soil, the last few weeks of veg use FF Grow Big only maybe add a small amount of molasses as a cal-mag supplement, and then the first few weeks of bloom use FF Grow Big and FF Tiger bloom and molasses and after that just use FF Tiger Bloom and molasses till just before harvest all at half strength by the way. Does this sound like a good idea?

Id try to lock in this line 1st before going organic. Watch diff strains react to it and figure out how to fix issues. Thennn try organic.
I transplanted around 12 at a time @5g pots, I used a big bag of promix, hf, and of. Mixed all that, and it fed for 4-6 wks ( all threw veg, mayybe adding a bit of calmag and bb on some fussy strains. Once I started flw, I started on wk 4 of the schedule. Trio, soluable trio, boomerang, microbrew and kangaroots ( and always a half tbsp of cal mag every feed). The newer stuff they added to the line is a rrip off ( kelp me, holymack, molasses stuff). I water enough to let it dry out in 2-3 days to incorporate the feed chart. Water water feed. I run t5's in veg and 1k's in flwr.
So far to fix my issues I : ph my water to 7 and fed 1x a week and the plants are taking up the nutes fine. Even in this hard ass water. And for my organic outdoor : I make boogie brew tea add growers recharge and also ad some oyster shells for calcium to my tea bags whilst ph to 7. I recommend pulling your light way up during the last mth- to 2 wks b4 harvest. It will still make em swell and they wont get too hot a fry. If you have lights on during a hot day and your room is feelin it, cut the lights off for a cpl hrs till it cools down, it will do a lot better for them not to have the heat stress.
