Yellowing, Brown Spots, and Curling HELP NEEDED

What is happening to my lady? It is starting from the bottom and working its way up. Please help before it gets out of control. I was thinking maybe potassium or phosphorus deficiency but idk. The 1st 4th and 5th picture are the same plant. The 2nd and 3rd picture are of another plant.

Can anybody help. I really could use it. And the thing is I just fed them Veg Nutes yesterday. If it is a phosphorus or potassium deficiency how long should I wait to feed them again with flowering nutes?

Anyone? Come on no one has an idea whats going on?

Check this thread out, it has helped me in the past:

It's is probably something you have give'em that did this.
This is also includes the dirt your growing and any nutes?
Next to take in to consideration would be your watering schedule.
Don't water till the pot feels lightweight!
Watering Is #2
Feeding Is #1

And these are the big "2" in growing!

This isn't your problem stride but #3 is lighting!

Why is everything cal/mag to me at the moment!lol!

I'm gona say cal/mag for sure or overwatering, both are easy to check. If ferts didnt solve this that is which by the looks of them they didn't. See why you think it is a pK issue but disagree there personally. Peace

A double check of the pics looks like there is a lot of moisture in the dirt & possible to much perlite, so I must agree over watering & or feeding is the cause.

Let your plant dry out, then only water it with water for the next couple of times. If this doesn't help you may need to transplant into different soil mix.

Peace out.

I know for sure it isnt my soil or overwatering. Just recently I found out I was actually underwatering them. I fixed that problem they arent droopy anymore. They are in FFOF soil and I heard you could never really have too much perlite.

How big is your pots?
I took a second look and
they look kind of small.
The plant looks bigger than
the pot and the pot is only
half way full dirt! Too small
of a pot will make'em droop
and make your leave look like
they have a deficiency!

Pop'em out of the pot it's
best to do it after watering
so the dirt stays together
better. Squeeze the sides
and bottom of the pot to
loosen'em up if you see
roots you need to
transplant'em!

I'd bet on it!
This is the easiest to check and correct!
It won't hurt'em to look!
If I'm right give me a like!

I'd repot them soon anyway but i'm still overwatering or cal/mag. Peace

They are 3 gallon pots filled probably like 2/3. So technically im going with 2 gallons of soil/perlite. Although this sounds like a great suggestion and maybe is the problem, I dont really have the money to get 9 new bigger pots. Ill give you a like anyways though.

Dont sound like there rootbound much anyway, id look into overwatering and cal/mag, easy to do and go from there. Good luck

How tall is the plant?
Most growers would put'em a 5 gallon pot now!
It don't cost nothing to check the roots~I could
be wrong it could be ph or feeding thats why you
check.

I just got some Epsom salt today. Ill use that and add some Flower nutes and see if that fixes the problem. I fed it Veg nutes a couple days ago and it seemed to slow down the problem. So I'm thinking it is just a P/K deficiency.

That plant is about 18 inches from soil. I really dont think its rootbound issues though. Ive read some people grew their plants to 5' in 2 gallons and thats when they ran into rootbound issues.

Too me epsom salts is just magnesium and not calcium. Plants need 3 times more calcium in the water than epsom salts. Adding epsom salts without the proper calcium to balance it will cause futher worse problems.

Dont think epsom salts substitutes for cal/mag as it just plainly dosent. Only cal mag in ratio 3:1 will solve a cal mag deficiency and needs to be soluable in water. My advice is try Evian mineral water or buy cal/mag supplements for water and ferts. Of course this may not be your problem but i would like to rule this out if it were me. Phone the water company and ask what the water ppm is, is it hard water or soft water?

At least you have somthing to check and rule out, ditch the epsom salts and get some calcium/magnesium.
