HYDRO JH & Ww

[FiNicks71]

Hi Growers
First time posting....I have 4 clones that aren't doing so well. Would love some advice on what to do, or more to the point what I am doing wrong.
Light on a 12/6 cycle
Watering 15mins every 2 hours
Ph level sitting at 6.4
A&B 2ml/litre - 50l reservoir

12/6 light schedule?

 

[FiNicks71]

Sorry....18/6

That's what I thought...I do not grow in hydro but the PH seems a little high. This link has some basic info about PH there is a chart in there that details cannabis nutrients and the PH range for the plant to be able to take them up. https://www.growweedeasy.com/weed-leaves-are-dying-help

Thank you..have read the GWE info regularly, ph is just in range so not sure what's seems to be going on with the plants.

I know you're done, but...
It looks to me like the roots dried out. Your drip line is going into the pellets, not over and the buckets are outside the reservoir. In hydro/coco/soilless, the roots have to be kept wet. That's a thing about growing this way.
Personally, in coco, I keep the pH around 5.8-6.0 for veg. 6.4 is for flowering.
