HELP it is getting worse. She is dying fast!

What is your feeding regimen?

 

[Dinger]

June 25: Water with a gallon included Flora nutes of 1/4 tsp of Micro, 1/4 tsp of Grow and 1/4 tsp of Bloom. Water ph at 6.6
July 1: water with water only a gallon of ph 5.8

Thanks for responding!

@Lowrider72 , @stoneotter - Any ideas? Nitrogen deficiency? Something else?

 

[Dinger]

Somebody suggested to feed her some food and add some cal mag. Thoughts?

If your in Coco you need water and 1/4 strength nutes everyday

pH at 5.6-6 after you add yer nutes

Really? I thought there was a wet/dry pattern one was suppose to follow?

That's in dirt

Yer not in dirt. Coco retains nothing as far as nutes, so the roots need air and nutes daily or they suffer

Thanks, @Chris Scorpio . I'm new to soil/growing and know nothing about coco. You're in good hands, @Dinger .

I just checked the runoff @ 6.15 ph. I appreciate all help.

Runnoff means nothing, it's what u pour in that matters my friend

 

[Dinger]

I appreciate the help, hopefully she will rebound!

Yeah mate just as Chris said give em quarter strength every day and they'll be sweet. Doesn't take much in Coco that's pretty much all there is to it lol.

Starting to show signs of light being too close?

So do I ever up the nutes? Or 1/4 strength forever?

you will up the nutes as the plant grows.

coco is a hydro approach, so you will be at 1/4 to 1/2 recommended bottle strength, for each stage, throughout the grow.
each stage has different recommended nute strength.

 

[Dinger]

Ah. 1/4 strength! Why was I thinking 1/4 teaspoon? So if my stage of growing says 4 teaspoon then I only use 2 teaspoon.

yes, depending on how you see the plant responding.
you may need to increase / decrease nutes according to your plants needs. different plants / strains may feed heavier or lighter than others.

i'm in hempy which has a similar feed schedule. i mix by ml per L, and feed using target ppm for each stage.

So I read about ppm. With only using 1/2 strength then there would be no way to active what is recommended. Is that right?
