Im just wondering how often you are meant to feed your plants? Is it a weekly thing or what?
Also I do not have a ppm meter so if there is a way to do it without one

Thanks heaps

Depends on your system (flood and drain, deep water culture ext...), medium (expanded clay, coco, perlite, rockwool ext..., and size of plants.

Many hydro solutions have a 1 tsp to 1 gallon -???ppm or it might be Metric this many ml per l = ???ppm

I am using deep water culture. The plants are in rock wool. So do you mean one teaspoon per litre weekly?

DWC you are always feeding. The roots are submerged in VERY airated water.

Get a hydroponic fert.
I suggest BCgrow, BC boost, and BC bloom.
PH balance your water to around 6
follow the directions on the bottle. It will say use x ml per 1 liter of water. there are about 4 liters in one gallon. Google metric conversion for exact conversions. So in this case if your resiviour is 5 gallons 4x5 is 20 ml of BC grow. Then do the same for BC boost. in flowering use bloom and boost

i have dwc . make sure the ph s at 5 to 5.9 nutes have a tendency to lock up quickly. I use d hornby's voodoo juice, piranha, tarantula and sensi grow a & B then use grow A & B. the sensi wean your babies nicely

A PH of 5 is way to acidic almost even for aeroponics

sweet as.. one more thing do I have to change all of the water or just add more nutes?

Change it all. Empty your res. With H2O2 (hydrogen peroxside) wipe the inside of your res down.

Add water
PH balance water
Add nutes based on instructions on bottle. Dont mix your stages of nutes together. Add them to the ph balanced water one at a time
