What might this be? Pics attached

Almost day 21 of flower. Yellowing leaves started more at the bottom and are now getting more to the top. They are also easy to pluck off and if left will wilt and fall off themselves.

I would say that roughly 1/5 of the leaves are now yellow. The ph of the soul pot is roughly 6.4.

I use Florflex nutrients and are following their schedule. I am not sure what is going on to be honest.

Please help.

This is soil? Are you using tap or RO water? any more info on what this nutrient schedule entails?

Soil yes with RO water. Starting EC is 0.0 and after adding calmag with the nutrient line it is 2.1. Attached is pictures of the B1 and B2 nutrients along with the foliar spray that is given on Day 1, 14, and 21 and feeding schedule.

Hoping someone more experienced jumps in here to help....What is the PH of the solution going in?....edited

At first I was going to say it looks deficient in P or K but after looking at the specs for your ferts it could be too much P.

Overall the pant looks pretty good so it could be strain related. I have a Monkey Banana kush that loses lots of leaves no matter what I do. If I feed it more it starts showing signs of nute burn and still drops leaves. When I feed it normally it does fine and doesn't seem to drop leaves any worse. Regardless I'm not going to grow it anymore as it doesn't have the buzz this old head needs. Gets me right f'ed up but doesn't ring any bells.

Your ferts seem to be lacking a lot of micro-nutes so depending on the soil/medium you are using they could be lacking a few things.

Are you growing in soil? That stuff is really only good for hydro grows, the N-P-K ratios 1-2-3 are not the best for soil grows!

Supposedly, the micronutrients are supposed to he more in the B2 and foliar spray. Sometimes I wonder if the foliar spray is burning the leaves directly.

There is missing micros between the 3 bags I looked at. There is no real reason for foliar feeding regularly and that for sure can screw your leaves so I'd stop that ASAP. Never spray with grow lights or fans on. I only ever spray when I'm fighting bugs.

Not sure that's the actual ratio but between the two bags for feeding the roots it's super high in P and the K is up there too with not a lot of N in comparison. Might work for tomatoes but not what I'd use for pot for best results.

The foilar is for Day 1, 7 and 14 of flowering only. This is now done. However, I am interested in the micronutrients that are missing. Need to know so I can correct.

Read this about essential plant nutrients and compare to what your nutes have. Going to be hard to just add in the missing ones so I'd get some better nutes.

You might be able to buy something with the micros and just add some. I have some granular ones somewhere but those take a lot of time to break down. They're called Frittered Trace Elements and was about $8 for a pound of them. I pulverize some of my own supplements to feed my plants. Iron, zinc, selenium, B-1, ascorbic, boric and citric acids. Not sure if it helps but haven't killed any plants yet. :)

Good deficiency chart here but you need to read the clues around each nutrient and compare to your plant's problems to see what symptoms match up the most. Bit of detective work involved. Save the chart for reference.

I think I’m having the same issues here, about 34 days into flowering. They are yellowing fast and some are falling off. It happened pretty fast.

Looks like low K to me. Pot likes lots of K and less P after the stretch so if you have something like that I'd add some but don't go nuts on the nutes. I have a bag of just K I like to give for a boost. Good old Epsom Salts will supply some much wanted Mg and S too and is cheap at any drug store.

You're not totally out of K but low enough that the plant is stealing it from older leaves as it's a mobile nutrient and can be relocated to where it's needed the most which is at bud sites now.
