[butucalexandra]

Hi guys,

I'm new here and new grower also ( my third grow ) I have a issue with my ladies and I can't figure out what's wrong and seems all people I asked has no idea what's this and also it's unpossible to stop.

I attached images 3 sets of images - 3 weeks ago - 1 week ago and 3 days ago! Any advice is welcome!

Thanks and peace <3

Looks like a potassium deficiency.

If it’s not nute burn and you didn’t feed heavy loads of nutrients.
then I would say Potassium deficiency also

I am leaning toward nute burn, but not enuf info to call it. Do you spray them with anything? What do you feed, what soil watering, etc.? What is the PH?

Thanks for all replies.

I'm watering them every 2 days, I'm growing in coco with Advanced Nutrients, I'm not spraying them and I'm not testing pH since the nutrients are pH Perfect. Seems you're right guys and seems to be a potassion deficiency. This is my 3th grow and I never had this issue. The only difference is.. I changed the location where plants are and the humidity it's higher, around 80% but I'm going to add a dehumidifier 1 week before switching to bloom.

I would give them a good flushing. With the way we all feed our plants, it can't be a genuine deficiency. It's probably nute lockout that's preventing the calcium from getting absorbed. https://www.growweedeasy.com/flushing-sick-cannabis
