Hello, I'm having a yellowing issue on certain fan leaves that's slowly spreading to other fan leaves, I've noticed that it seemed to have started as the plant started flowering about a week and a half ago. I cannot remember the strain, the plant was given to me and it was very stunted for a long period of time before taking off quickly in the last month or so after using grow big. I'm using FFOF/earthworm castings/tigerbloom (per fox farms schedule) in a 5 gallon pot, and I was going to start adding some guano in case it was a nitro deficiency issue but I am new to this, and didnt want to over fertilize! Plant is usually watered when pot is light and soil is dry when I stick my finger in there, so I don't think it's an overwatering issue, but maybe I'm wrong! Any advice? Thanks!

I'm having the same issue.
You said you were just using the tiger bloom.
Same as I
After a few watering of JUST tiger my plants started yellowing then canabalising themselves
Burnt crispy leaves.
I THINK its because i was only using the tiger and not the big bloom like the feeding chart said to.
Think I caused a deficiency because it isn't getting the nutes it requires from just the tiger.
I'm not an expert tho.

Looks to me like Nitrogen Deficiency.
Many mistakenly think in flower they need LESS Nitrogen, when in reality, they need more, of everything.

Hit 'em with a shot of 20-20-20 Jacks veg. nutes (or Botanical Veg nutes, or whatever ya' got) to green them up. Farmer advises doing the 20-20-20 augmentation only once, before harvest, but I've read in my notes, that he once said, 20-20-20 could be used as much as twice before harvest (referring to my long-running sativas.)

Those plants haven't been flowering long enough for them to be fading out yet. Yellow is starting at the bottom, and is also starting to get pale in the top leaves.

Check out the PPM on this Feed Chart from Chem Gro/Hyrdo Gardens
These people have been making PLANT SPECIFIC FERTILIZER SINCE THE 1965
Not saying to use their fertilizer either.
Just the FEED CHART.
The plants get more, and more of everything throughout the grow. except for the last 2 weeks, and then its only scaled back a little.
This formula is used by Tissue Analysis. Not GUESSING/ASSUMING.
And even though this is for Hydro, the same applies to soil. Just the way to go about it is different.
Weed likes a 19.5 - 20 - 39 base formula, and rich in cal/mag depending on where you are at the cycle, and a boost in P/K at early bud set
This will show how the PPM keep going up all the way through, except last 2 weeks. Magnesium goes way up in weeks 5-6.
In the 3rd week Everything gets a boost. Nitrogen incl.
The Nitrogen needed in week 8 of flowering, is DOUBLE as what is needed at 4 weeks veg.
This is for an 8 week strain.

I think this is a very important distinction. I have yellowing at the bottom too, but all other growth is green and healthy. The only leaves that are yellow just slowly fade to yellow and can be removed with little force, while all the growth around the yellow leaf is healthy and green from stem to leaf tip.

pluck the yellow leaves off. hit them with nitrogen to slow it down. it's ok to feed low amounts of nitrogen early flowering. you might as well start plucking big water leaves out since they tend to yellow first.

If a leaf is starting to yellow leave it until the plant has sucked all the nutes out of it. They are deficient in one way or another due to some sort of lockout potentially. So any leaf dying is getting used by the plant. Pulling them off before their totally used up is a waste

ever heard of defoilation? many growers pluck out big water leafs even if they are not yellow. it promotes air flow, controls powder mildew and concentrates energy to the buds. if they are still green and starting to yellow hit it with nitrogen. but if they are yellowing as shown on ops pictures they will snap off with out any pull effort.

yes but leaving yellow leafs is not good advice either. op can choose to follow your advice if he likes. no one cares more about his plants then he does.

Its not leaving shriveled up totally dead leafs... all i saying is to let the plant get all it can from dying leafs before removing. Simple stuff...

Likely has to do with what you're feeding unless it's a pH related issue (or could be both) there's a product called Mega crop from Greenleaf nutrients who advertises here, that might be perfect for you and other beginner Growers as well, it will give your plant everything through its whole life-cycle so you'll take that issue out of the equation. I haven't used it yet but enough experienced growers here have said so many great things about it that I'm sure it will work for you, good luck!
Lots of good info, thanks!
Thanks for the replies everyone, I addedd some big bloom along with the tiger bloom this past feeding and the addition of the big bloom seemed to slow the yellowing down quite a bit, but some leaves are still yellowing. Used the quantity recommended on the fox farm feeding schedule.
sounds like you need nitrogen.
