I need your help! What is going on?

[Strudel]

Hello , i have a problem , or multiple problems...I have one blu hawaiian sativa in coco coir under 400 w hps , i used guano kalong already mixed with coco before seedling... And during plant's life iam using plagron power rootz and kalong grow ( NPK 6-0-3)a product combine with the use of guano that is basically only phosphorous.

In my opinion can be:
calcium or magnesium deficiecy/nitrogen toxicity / nutrient burn/ phosphorus deficiency or russet mites (as one plant before had it ) ...


What do you think? I will add some photos of the plant and of the leaves.

Far as I know loose coco can be added to a soil mix or used straight up with or without perlite. Coco don't like what you are trying to do. You have a good lockout going on and I don't see a way to fix it seeing how you added guano to the coco. Use a good organic soil mix with coco or use salts in straight coco. With a lockout like you have usually a good flush would help but you might wash away the cation bank and get another problem. Goodluck!

Sorry for my english so can you see the photos? I can't put it propely ...no idea how is working ....anyway I do not undesteand : is a problem of to much nutrient? A calcium or magnesium or phosphorus deficiency? Or russet mites?


And why the new grow leaves are pale green and curly and so harsh to touch ? And why old leaves are loosing colour and have dark spots?

Start with checking the pH of your media

stoned40yrs and MrBungle gave about the best advice possible. The nute lockout shows the plant dosen't like something. What is your ph running at.

 

[Scrappy-doo]

If another plant had russets you should assume this one does as well based on the damage. But looks like you have other problems too. Some good advice here already. You need to scope for mites as well.

Was around 6.4 but now i fixit about 6.0 ,iam in coco..
I know was abit high..now is 2 weeks is fixed..

Iam flushing ...i mean iam just giving every 2 days water only with ph 6.0 And two times ,one a week , i gave advanced nutrient cal -mag

My question is how many weeks do i need to wait normally for new growing after a lockout in marijuana plants?2 weeks iam just giving water without npk... And still leaf looks little and wit rusty surface

You have some kind of pets possible broad, russet mites. HIt this plant with poison. In coco everything happening quickly 2 weeks without growth is too much
