start of nute/ph lockout?

one leaf doesn't make a problem, older leaves dying off is normal.

Red stems can be lack of available sulphur or strain related. Edit : Phosphorous not Sulphur..

When in soil then adding 1/2 mil of cal/mag supplement per litre of nutes is beneficial every 2nd watering

It's why I said not to worry about shit op.

You need the bigger pot - your transplanting tomorrow.

The original problem to your post was calcium, because your nutrients don't contain them. Possibly sulphur - you're amending your soil with calcium sulfate tomorrow.

You may need extra magnesium along the way. You're amending your soil with a handful Epsom salts tomorrow - magnesium sulfate.


Solution op. Is to just transplant to a bigger pot tomorrow, with amended soil.


Good luck op
It'll be fine.
Plant will be much happier.

its ok if i add calmag before ph down or its added afteryou ph water?

You can't do that with organics unfortunately.
The soil is your medium. Not your water.
My original advice still stands.



As I suggested a tiny bit of 1.0.0 calmag before you lime too. It'll temporarily improve, until th lime starts to kick in.
Just don't use the calmag after you lime. It'll be useless, because it'll just attach to your lime. Instead of dispersing through the media.


Good luck OP.

What I'm suggesting. Is if you amend your soil, you shouldn't have to use any ph down at all.
I tend not to mix ph down in when I dose calmag at all.
Calmag is useless after lime.

You shouldn't have to ph water for soil.
You buffer the soil. Not the water.

When you add the gypsum. To a 5 gallon bucket. I reckon three hands of gypsum and one hand of Epsom salts. Mix it all in.

I'd say.

3 to 5 handfuls of gypsum.
1 handful of Epsom salts.

You shouldn't need any of your nutrients for at least a couple weeks.

Just h2o bro. No ph down. I never have. Never do. It's soil.
All you do with soil. Is make sure ph is right when you plant. And that the soil is amended.

OK.
You'll need the gypsum. Definitely.

Good luck op

Are you using soil? Or a soilless mix like bio bizz or ff?you shouldn't have any issues with calcium at this stage, after reading the above he's right about needing to transplant and this is cause of all your problems, giving extra nutes to try and correct the smallest of problems is not a good idea imo when everything will be ok after transplant . You will never see a plant with every leaf in perfect condition. Your worrying about nothing. Cannabis is difficult to kill in soil/soiless. In soiless I'd recommend phing as the manufacturers base ph levels in each bag fluctuate greatly. Make sure you evaporate the chlorine out of your water if not filtered as this renders some nutes redundant as well as hinders bacteria growth
