Ok then we should be looking at week 4 of the veg section for everyone except the blueberry.
Week 4 veg calls for 650-900 PPM and for the Blueberry, Week 5 (Early flower) calls for 500-700 PPM
So if your runoff is between those numbers, then you don’t need nutrients.
Blueberry Auto: 648 (within ppm specs)
Pineapple Haze: 384- LOW
AK47: 542 LOW
Sour D: 710- OK
Bubblegum:494- LOW
Strawberry: 581- LOW
So now when you look at that data you are surely thinking that it would be impossible to water all of these to the proper TDS PPM
I would look at the average PPM and feed to that number which in your case is roughly 500 ppm.
I would feed them to get them to the middle of the scale of like 800 ppm so that would be roughly a half feeding. For all of the photoperiod I would feed the first feeding at half strength and the following week at full strength (week 4 schedule) until you decide to flower them. I would start them on bloom nutes (week 5 and beyond) as soon as you are ready to flower them.
The Blueberry Auto, even though the TDS is within range, I would give her the 5th week nutes at half or less. She is going thru a big transition and the nutes will help her tremendously!
It is good to spot check the TDS.
It is most important to get the pH exactly where it needs to be! I always ensure that both water and nutes are exactly at 6.5 for my FFHF soil and my girls are happy!
Do you have cal-mag. I like to add cal-mag to my nutrients once a month beginning at week 4 to keep them happy (Especially the autos) @VelcroThumb
I have given my opinion on this and opinions are like…well you know. There are many ways to get the job done. You will find your method and stick with what works! There is plenty of room for other ways. Hope this helps!
