? about flushing to remove nute build up and salts

[sourdieselyumyum]

can I use florakleen and do 5 gallons each per 5 gallon smart pot and be good or do I have to do 15 gallons per 5 gallon smart pot?

You should do what it says on the label.

The most I've had to use from products I've used in the past was 6 gallons on a 5 gallon pot.

well when I contact general hydroponics they say a little more than what I normally water with which is usually 1 gal but ive recently uped to 2 gallons I don't see how 1 to 2 gallons with florakleen can really do the job im in week 3 almost 4 of flower and need to flush cause I think I have a build up of nutes or salts that are locking out certain nutes like calmag so I was thinking 5 gallons each should do hopefully then ill start back with nutes at 1/4 dose or so

If you can for-sure keep the flow directional, 5 or 6 gal will do.

I flushed my 7-gal SmartPots once due to salts buildup. I monitored TDS of effluent. Took a good 10 gallons each to get from >1000ppm to a good 250, using 70ppm tap water. cn

best flushing agent for over nute is WATER! And don't PH it or anything prior when flushing soil!

You should absolutely pH your water if necessary.

Getting your pH out of range would just worsen your nutrient problems.

here is a few pics of problems im having looks like calmag def but ive been giving plenty of calmag also having brown dry curly yellowing tips leaves on bottom

Cal/Mag issues are more often a problem of nutrient lockout due to low pH than actually a deficiency of Cal-Mag in the soil. What is the pH of your soil?

soil run off on all them are between 6.4 to 6.9 I think its from too much salt build up or something maybe ive been adding too much calmag I add 5ml to a gallon

I just flushed each with 5 gallons of ph 6.8 water with florakleen all ph are 6.5-6.8 and ppm are all under 600 do you guys think I got I the excess and nute build up out

What were your starting and ending TDS? cn

 

[sourdieselyumyum]

all of them were over a 1000+
