Curling yellow leaves with brown spots help!!!!

I have a plant that has been flowering for a few weeks and it doesn't look good at all. The leaves at the bottom going up started to yellow and curl so I've been cutting them off and going up as they get really bad. The problem worsened and the rate of yellowing/brown spotting has gotten faster. Now I have almost no leaves left on the plant!! It's really only a stem with one cola/bud formation now. I didn't cut off the leaves in the picture yet (so I could take a photo and show you guys what I'm talking about!)

I looked up plant problems online and the picture seems to match with a manganese deficiency. Does anyone have any suggestions on if this is the right diagnosis or not? Also, how can I save my plant???? I haven't done anything yet to fix the situation, not even flush. I'm only using FF Big Bloom so I may need to get another nute or 2.

Thanks for any help I really need it!!

When you have a manganese deficiency, its usually caused by a high ph or too much iron in the soil. Whats your ph like, and how much iron is in the nutes you are using?

Thanks a lot for your response jesters. I'll take the ph later today as soon as the lights come on and will let you know. As for the iron, the flowering nutes that I'm using now makes no mention of any iron in it. There was iron in the veg nutes though but I haven't used them for almost a month now and there were never problems during veg.

that almost seems like nute burn.
how much are you giving her?!
but then again dont know for sure.
but ive seem peoples grows where theyre using too much nutrients and thier leaves tend to turn yellow first and then get these
ugly brown spots all over.
maybe try flushing a little....good luck

I think with the foxfarm nutes it's best to use the line of soil with
the whole line of nutes. I follow the feeding schedule almost exactly. When I first start giving the plant nutes I start
with half stregnth for the first 1-3 wks (depending on the size & how well the plant seems to tolerate the nutes)
Here's the full suggested line & ff feeding schedule hope it helps! http://www.foxfarmfertilizer.com/soilfeed.pdf

Thanks a lot Shylas. I think I'm gonna go ahead and flush the plants, then pick up the FF Tiger Bloom. Hopefully that will save the plant.

Yeah, actually that could also be the problem!!

Good luck with the flush bucks!

Usually curling leaves with blotches and burnt tips are from a lack of phosphorous and spots and rust along the vanes is from a lack of potasium. They use a lot of P during the whole cycle, and mass amounts of P and K during flower. After the flush use a fertilzer with a lot of P and K and very little N in it! The recomended NPK for pot in flower is 10-30-20 and 10-10-10 for veg. I use FF soil but I mix my nutes to get as close to the recomended NPK as I can. I mix FF Grow Big and BioBizz flower for veg and FF Open Sesame and Supernatural Bloom for flower. Good Luck! Hope your little girl makes it!

phosphorous is a main cause of harsh burning bud as well...too much P and you will be coughing up a storm.
keep it healthy

im not an expert or n e thing, but i dont think its good to prune too much in the flowering stage either cuz all the plants energy will go to healing instead of flowering....
