I have grown outdoors for about 10 years on and off and a few years indoor with soil in college so I decided to give a DWC system a go.
I built my own set up using a 27 gallon well(18 gallon nute solution for 4 sites.
The system has two air pumps running:
4, 4x2” airs stones under each plant site as well as a fixed 12inch bubbler stone in the middle to offset any current created by the airstones.
I just put them to flower (12/12) on 7/16.
They were vegging for two weeks with a 24 on the first week, then 18/6 Second week, then the third week
Slowly dialed back light an hour a day increased light intensity then went to 12/12.
My First week I did what seems like a lot if first timers did and overnuted the sh*t out of the transplants so it took a good week to flush out and get them healthy. So they really only veg’d for 2 weeks in my ignorant opinion. Ha
Air temp ranges from 72 to 81degrees Fahrenheit
Water temp ranges from 70 to 73.4 degrees Fahrenheit
Humidity ranges between 49% to 64%
Root medium: clay pebbles in 4 inch pots
The last solution change was the beginning of the third week and started them at 500ppm’s
The Ph ranges from 5.8-6.1
I have been upping the nutes by about 25 ppms a day and have been at 600 for last day or two.
I use general hydroponics (green/orange/brown) nutrients, as well as
Sorry I am allover the place trying to give as many details as i can.
My concern and reason for my post is that the color of my leaves are a bit lighter than I expected and compared to the mothers and I was not sure if that is cause by a silica deficiency or is it normal or is it something else or am i being over critical. Do i need foliage spray?
The reason i suspect it could be a silica issue is because the mothers have had a lot of silica in their soil(use DE To deter pests and as a secondary effect To condition the soil a bit).
I just ordered botanicare silica blast And plan to add that this weekend just in case.
Any advice would be greatly appreciated…
