It looks like cal mag is in order but lets see what the OP says.


Look here

Looks like critter bites from underneath on bottom of leaves.
Use a magnifying device and closely inspect entire plant, pot and soil etc.

Never would have crossd my mind…

It’s funny since I’ve been going through dealing with them it’s the first thing I look for in pics people post with issues…
Like when I bought a Subaru the first time…that day I saw them everywhere but before not so much.

I thought it was just my eyesight lol


@Paddynix 27c is to hot but it looks like a potassium issues what week of flower are you in some of the leafs will die off even if there are no issues it’s normal but try to get room alittle cooler like 22c is good place to be if I’m doing my math right 27c is like 92f let me look it up to make sure but I would most def say it’s a potassium thing yep looked it up 90.5F is to hot in flower the temps in nature are 70-75 so 22c puts you at 71.4f that’s perfect for flower so again get temp down alittle if possible and remove the dmg leafs so your plant isn’t trying to heal a dead leaf. Also 18c-27c is to big of a swing keep the swings about 10-15F from night to day so In Celsius you want the swing to be about 5C you are swinging 9c so that is about a 27F swing and that’s to much well more like 4c 1c is equal to 3.4 f so 4c would be your max swing


@BigDaddyCain never realised! That sounds about right gonna change the set up. Thanks for your effort to reply I was stumped on this for a while, top man!!
