I have 2 girls scout cookies in 5 gallon pots. I use all of the fox farm nutrients and go by a nutes chart I found on here.
I is great and I is having I believe a nutes lockout and I want to flush it.
They say 3x pot size so I’m looking at 15 gallons of water. I live in the village in a small NY town, so I have village water and also a water softener. When feeding I use 1 gallon bottles that I refill in my kitchen because I installed an RO system. I had to go with a tank one as I do not have an outlet under the sink. It’s a 4 gallon tank and I usually fill 2 gallons at a time as they are not the fastest things in the world and after 2 gallons it slows down a little bit.
Sorry if this is a dumb questions.
When flushing, do I have to use 15 gallons of R. 0. Water or could I maybe use 10 gallons of regular village / town tap water and then do the last 5 gallons in ro water?
I’d let the water sit for a few hours then pH the water to 6.5 before flush.
I think you’d be ok with as much RO as you can supply and add tape to top off your flush.
I would recommend some flush additive to help remove salts.
I use FloraKleen but I bet FoxFarms has something similar.
So it really depends I’m in coco and also in 5 gallon fabric pots. I recently had to flush and what I did was I just ran water through it until the water came out clear. Not yellowish or greenish. I ended up having to use 3 gallons. As long as the water coming out is clear then you should be flushed enough to rid the problem.
Flushing is generally used to reset the PH or lower the nutrient PPMs in the Medium Growmie, it’s a guessing game or risk if you flush and don’t check the PH or PPMs from the run off
When I very first did mine I was having some deficiencies going on. Spots leaves turning yellow etc. so I went ahead and flushed it. Started adding in cal-mag and for 3 days she started to look good and then went right back to having problems. Came to the conclusion I was messing up the coco by allowing just the self watering base to feed the plants. Since then I started to go back to top feeding twice a day and since then she’s started to come back around to being green. Ppm was over 4000!!! And that’s because i just kept feeding it nutrients. I never did the fwwffwf to keep it from building up. Now that I got it on the routine I’ll show the before and after. But yea. I would get run off number and all first before going digging for a solution to that.
Before
Using 10 gallons of tap water and 5 gallons of RO water for flushing is a decent compromise. Tap water will flush the system, and RO water will remove remaining minerals. Just be aware that tap water may contain minerals that could affect your plants.
Low ppm while using ocean forest soil and giving It the recommended nutrients. I even raised the nutrients. The leaves started turning yellow and the growing seemed to freeze
