Are the roots in the water yet? If not try top feeding. What's your ph at? What kind of water? Looks like there not getting nitrogen.

Hi,
Thank you for your response.
*Yes, the roots reached the water.
* 5.9-6.4
* Tap water
* I am following rosman tutorial in this site. I fed them with 1/4 till I have reached the full dose. Yesterday I have change the water with lil biy less then full dose as the nuts instructions.

I have checked ow and it seems that my second plan becoming the same and also fold

It seems like a nute lockout, maybe do a water flush wait a day and then start again at 1/4 nutes for two weeks and if all good it to 1/2 for two weeks and if all good, then go to full.

How long the plants can be without nuts?

What is your ppm at?

 

[mushmushi]

Sorry for the ignorance... What is ppm?

Sorry for the ignorance... What is ppm?

Parts Per Million basically how much nutrients and or minerals are in your feeding water and as for tap water as you are looking for......

Here are some good guidelines:

Tap water: 400ppm or below; 400 is high for tap water.

Nutrient Water: 400ppm - 800ppm total

DWC Reservoir water: 400ppm - 1000ppm

I don't have a ppm meter... Is there any way to check it?

I realised that I have a tds meter.
I filled 1 liter of tap water and measured 245 ppm
Then I added the nuts as instructions and pH the water and I have read 375 ppm

I'm lost

375 ppm after nute introduction to the PH'd water should be ok as those amounts i posted are just a guideline.
