Help to figure issue

[Asho p]

Hi guys so all my girls are growing really well and over night I've noticed this has happened to one of my plants,

room temp and hunidity is fine and I haven't done anything different?

anybody got any suggestions?

[Marley]

I'll ask what others are going to. What's your water source? Are you PH'ing the water? What's the PH of the run off?

[Jeg]

I'm not an expert at all but im curious about your ph? Marley that was weird

[Marley]

I'm a wizard.

[Asho p]

My PH is 6.5 every time my friends

[Jeg]

Always a good place to start. Sorry

[Asho p]

I'm unsure what else to do I'm afraid...leaves are dropping and main stalk has spots on it?

[Jeg]

Any change since yesterday? Has it gone through a dark cycle yet? I'm no expert but I'll treat it like mine. You said ph is fine water,soil, and runoff. Can I see spots?

[Jeg]

I don't personally touch my plants much but I would here because I'd want to know texture of my leaves brittle, glossy, stuff like that. And the spots. What's that all about? Roots? Just brainstorming. Keep us posted

[oldjarhead100]

just from the way the leaves are drooping I would suspect one of the following . root issues-flush with flora clean and then flush with phed water to raise ph from the flora clean, mites -spray with aza mat its safe at all stages. and even though your water is 6.5 the plant itself might want 5.5 or 6 . different strains like specific ph values ( I know sounds crazy). I would try the flush first unless you can see mite though your microscope good luck

[Asho p]

Hey man, I can't find any mites on the plant at all, and this girl is in 60 litre pot so how much ph water would you advise to give her I normally give hem around 3.5-4 litre?

[Jeg]

oldjarhead100 thanks. I wanted to help but like I said I'm new to this

[Marley]

I'm no expert either, but the closest thing I could find that look similar to your issue it potassium deficiency. What are you feeding it for nutrients?

regardless, it seems to be a nutrient issue. Some sort of deficiency or toxicity. To start with, I would flush it with PH'd water until you get a lot of run off.

[Asho p]

I'm using advanced nutrients micro grow and bloom that's it but stopped about a week ago and just used ph'd water with abit of liquid sea weed extract?

[Marley]

Why did you stop the nutrients? That's probably why you're getting a deficiency. You shouldn't stop feeding until the last week or two before harvest.

[Asho p]

I just had a panic moment and thought it could have been that, but it was due a feed last night so put it back in the feed then hopefully it will will be good after a couple of days it's only had one feed without nutes but it looks to be dying to be fair now
