How to Make Hydroponic DWC Top Off Water
Hydroponic and DWC reservoirs need to be refilled to be just under the netpot so that your plants roots are submerged as much as possible. When using synthetic nutrients, the pH tends to fluctuate and most times, it will drop so mixing in some pH up or down allows you to replenish the water while simultaneously balancing your pH. This recipe also adds hydrogen peroxide to keep your buckets sterile and Epsom Salt for additional magnesium in veg.
The method of using this type of feed starts with refilling your reservoir with this solution, then adding your juices:

My PPM when starting was a 0, I got it up to 205 and than added the plants to my buckets, second day going in to add top off water and Juice but my PPM is now reading 240 and PH at 6.5. Worried about adding top off bc PH up and worried about adding juice bc PPM is so high. and recommendations?
means the ppm is too high and the plant is rejecting it, dilute the water down to 180 ppm and target pH to 5.6. This abberant ph and ppm shift may be a sign of root rot too, so you might want to double check to make sure nothing is wrong.
For the top off water, you ad PH up first, should i add it first or should i PH my resivour after i added the top off water, h202 and epsom salt? My RO Ph is around 7. Thanks, This is my first time trying hydro and i’m learning a lot. thanks for all you do!
Ph up last
