That depends.. If you use water with a zero ppm, like RO water, there is no subtracting to do. If you use tap water that has a ppm of say 200.. Then you subtract 200 from the run off number to get the run off ppms. Here is the chart I use for ppm levels. Keep in mind that every plant is different. Some can handle heavy feeds, while some hate heavy feeds. This chart is a good reference point though.

Thanks!

Day 49

So I check the ph of the soil and it was 7.5

So I flushed with rain water that was ph at

And ppms was

1st flush numbers coming out are ppms

Ph

After 5 gallons ppms, and ph

And soil ph is just about 7

I dont have anything to bring down the soil ph. Is there anything I can use?

It can be difficult to change soil pH With a live plant. You can feed with nutrient at a slightly lower pH then you normally would use. When the solution gets into the soil it will raise the pH of the nutrient closer to the soil pH and eventually bring the soil pH down. You would want to monitor both soil and runoff pH if you do this to keep track of the system.

I think you should raise the Core B used as well, it seems to need it back.

:smoking: I think you're A-OK Al,.. that meter, I know the type, and they are not very reliable and those pH meter reading prove it... No waaay it's 7+ when first test of actual run-off is in the 5's, trust me! You would have had definite lockout defc. of some sort of micronute, Zn and/or Fe most likely, no matter how well chelated... I'm surprised you didn't have other symptoms from such low pH, like P defc, or Ca,... I'd say the PB worked some magic here for keeping the nutes protected, plus 5.75 is probably lower than the actual in-pot pH in general... That first bit of r-o tends to be rather concentrated, like a drip-cone coffee filter does with grounds... So, it wasn't too far off in there, I'd say - .... r-o ppm's were not bad at all, your feeding has been on point otherwise, IMO,... now after that flush, it's showing to be stripped, so feed ASAP... Usually it's a good idea to use about 1/4 strength nutes on the final pour through to help restore a little feeds while the pot dried from that epic flooding - ... keep your feeds at about 6.5 now, the soil's buffering capacity is probably pretty tapped out at this point.
Buds are forming up well mate, swell is on! .... resin production is really good too,....That color never gets old - -- how does she smell?

Thanks guys, this is a big help! That probe I've had since I started growing and has help along the way more than once!!
Day 50
I've made a new feed yesterday

Water source: rain water
Ph before nutes

After

Ppms before nutes

After nutes

Week 5 flower feeding schedule

5 ml Bio-si
10 ml Core A
8 ml Core B
5 ml Big-data
5 ml Kelp-ful
5 ml Precursor

Will give it to them later on today. And she smell gooooood!!!
