Im new but I agree. That PPM is twice what it should be on the Kush and lower than it should be on the GG4. You can even see the nitrogen and probably potassium deficiency clearly. Since the GG is looking ok that hot I wouldnt flush....yet so yeah straight waterings. Are you positive those numbers are correct?
I dont either, thats interesting. Tighter packed soil? IDK.No, they were not correct. I was wrong about the Kush Mints. I retested and Kush Mints (bottom) were at 980 while GG4 (top) was still at 630. I have edited the original post to reflect the correct numbers.
I want to emphasize that these are numbers I'm getting when I put in plain water, which has 220 ppm. So, the Kush Mints runoff is more than 4 times the ppm of the water that went in, while the GG4 was around 3 times the ppm going in. I have no idea what significance that has, if any. I'm brand new to this.
Check out the runoff of new ff soil. Mine varies from 2000-3000ppm.No, they were not correct. I was wrong about the Kush Mints. I retested and Kush Mints (bottom) were at 980 while GG4 (top) was still at 630. I have edited the original post to reflect the correct numbers.

Yeah , measuring PPM in soil is a waste of time.....
PPM readers, measure the level of dissolved solids ina liquid....is used in soilless medium to calculate the total amount of nutrient that you aim for....
In soil you have too many dissolved solid that arent nutrients so you arent calculating the amount of nutrients but them togheter with other unknown particles....like....mud.. etc...
Long story short....measuring runoff will be very decieving and confusing.....leave it for the hydro peeps
Another point to consider is that you are using a mix that have peat in it, that means you have a pretty good CEC level that will keep some nutrient bond to the soil and the water will be unable to flush em away.....another reason why analizyn the runoff of a soil grow is not helpful....
Check out this video on YouTubeMy instincts tell me I should feed the GG4 more than I have been, and not feed the Kush Mints anything but plain water. Is this the right answer?
Does the fact that PPM is more coming out than going in mean anything important?
