They are eating like MAD. I would add 1 gal of my mix made at 100% should ph that to 6.0, just over fill. I am sure your system capacity can handle the extra one gal.
Peace,
i have a new problem know..
the leaves getting pal green and some brown spots like
burnt.
ph is stable at 5,9 and the ppm are around 500.
is there a case for underfeeding and the leaves are like this??
maybe is a calmag deficiency.i dont know at all.
i need someone who knows about DWC for my questions.
can you help me please?:
3.8 L = 1 gallon.
My grow blend is 10ml micro 15ml grow 5ml bloom 5ml diamond nectar 5ml Becauzz Grow.
I would mix that in 7.6L of water and it should read between 700 - 800 PPM.
I make it less strong when the plants are little but yours are big.
The leaves with damage look much older than the new healthy green leaves. I think you are doing fine. How about pruning off the damages leaves? It looks like the rest of the leaves are preforming great.
5g a day, we are brothers!
I wouldn't worry about Cal / Mag def. I have never adjusted by adding cal or mag and as you said my trees and even failed little plants speak for themselves.
Peace,
