Mottled leaves undersides are red?

Is this a deficiency or?
Runoff ph of both plants is fine (6.2 and 6.6)

Feeding schedule is as follows per gallon
Biothrive Grow 5ml
Biothrive Bloom 10ml
Biobud Bloom Booster 5ml
Bioroot 5ml
Bioweed 2.5ml
CaMG+ 10ml

With flowering just getting underway it'd be nice to get this under control before its too late.

I use the same nutes in coco. How long have you been on that schedule and when did you start noticing problems? I usually go 5/5 on grow and bloom in the first two weeks of flower. I stop bioroot late in veg. I wait until two weeks into flower for biobud too. I've noticed you have to be careful with that one. A picture of the whole plant would be helpful.

I'm not at home atm but to give you a better picture its really only new growth having problems underneath the canopy as well as the fan leaves. They are having this mottling. Its been going on a while and growth has continued but at this rate I won't have any fan leaves left by mid flower.
The upper leaves on the main stems are a nice shade of green and appear healthy.

Post a picture of the whole plant when you get a chance. If it's only happening near the bottom and they are really tall, it might not be too bad. I'm not really getting what you're saying though. That first picture is definitely concerning if you are seeing a lot of leaves like that. But if the top half of your plants are looking good and they're pretty tall, then it might not be a big deal.

Those look great, IMO. All the problem leaves are at the bottom and their 5.5 feet tall. Actually, that second one has some further up? Hard to see in the pic. If you have a lot of leaves dropping higher up on the plant, I would worry. Maybe a little N deficient? What were you feeding before you switched to flower? Were you feeding with every watering?

Thanks I'm impressed at how big they've gotten.
The main cola stems have a few yellowing leaves further up. The affected leaves seem to mottle like the pics posted then turn banana yellow and can be pulled right off the plant with a gentle tug.
Usually I try to feed them every other watering. I was feeding the same nutrients at 15ml for grow and 5ml for the bloom and have been steadily decreasing the grow every feeding and upping the bloom.

That's similar to what I feed. I feed 10ml of grow and 10ml of camg+ every watering. So 20 every other is the same amount of nutes. I usually lose some fans in the first two weeks of flower but they usually don't turn yellow first. How big are your pots? You usually want 1g of pot per ft of height. Maybe you need to bump up 5ml to make up for their size relative to your pots?

Plenty big then. Unless the problem gets worse, I would wait to see if they stabilize a couple of weeks into flower.

So it looks like one plant has begun to recover amd the other is still having this problem. Its little budlets dont seem to be getting any bigger and some of the upper leaves have started to die from the tips out. Some of the leaf margins near the stem of some leaves are having the same browning. I don't have a clue whats going on my PH is about right.

Could the root system be too dense? Is that possible? I watered them both the other day and it took almost 5 gallons over the course of an hour or so before the top inch of soil had even started to get moist most of the water just ran down the sides and out the bottom. I stuck my finger into the top layer of soil and the roots seem to be so thick that when watering it seems to just run right over them.

I think I found the issue when watering. I think the soil I'm using has a lot of peat moss and its not absorbing water like it should.

This is still ongoing and I'm no closer to figuring out what is going on with my leaves.
Runoff water tested at 6.3 PH after watering with water straight outta the well PH'd to 6.0.
Has no one had similar leaf problems?
I'm sure its not the end of my plant but its getting worse and NOBODY has been able to give me an idea of what Im dealing with here.

Anybody?

I'm stumped because of the pattern of yellowing its kind of everywhere but mostly affecting fan leaves. The affected foliage yellows in patches with areas of dark green and the bottoms of leaves have a rusty color in places where yellowing on top of the leaf is most prominent

Are you in soil or what? PPMs? Is it super hot where you have them? In general people feeding that many products don't under feed a whole lot.

Yeah theyre in soil and I'm not certain what ppm the nute solution is.
It does get pretty warm and they are in black pots so that could be contributing to it.

I have so many ideas about what it could be. My well water (straight outta the ground) is high in iron and my tap water is softened.
Someone told me it looked like multiple deficciencies. Namely NPK and Mg. There is no reason this should be happening. My feeding schedule seems adequate and the soil ph hovers in the low 6s so could there be too much calcium or something locking out my other nutes?

I've got an unknown strain of NE indica that is doing great on well water.

how big is that pot ?

Theory one lower leaves being eaten to support budding and rooting for flowering

theory 2 lower leaves being eaten due to N probably p and k shortage too

Maybe its just my style but I`d strip off the bottom 2 to 8 nodes, focus on top bud, but I guess outside its nice to leave lower stuff on so the bugs have something to eat.....

One is in a 14 gallon the other is in a pot thats roughly 26 gallons.

I don't really want to just go in and start chopping stuff off tbh. I've got the bug situation handled for the most part aside from leaf hoppers.
