I think with FF you would flush #3 with water until the runoff pH is in line then feed. I have no experience with synthetic nutes, just what I’ve gleaned from browsing posts here. I’m sure someone will be along shortly with a better plan. They look a little thirsty, btw will probably appreciate the drink

In flower you want to try to hit on the higher end of 6.5 to 6.9. Notuce the one thats doing great? Try to match the other ones to that. But #3 is the one to startvwith

Good info, for now and for future tracking and learning patterns and tendencies.
Over 7 eh.
No sir 
I dont like it.
I didnt get above 6.9 ever yet so dunno how to treat that one.

Great info, will do. And I should feed the the ok ph ones now correct and check runoffs? What’s my target range for ppm’s after feed? The fox farm trio feed sheet says 2380-2660ppms at week 8
Not sure what I do with that info, really
Thank you kindly

Every auto ive ever grown ive kept ppms between 800 and 1000. Autos are real finicky with nutes, so when mixing nutes start at around a quarter to half dose at first to see how they respond. Also remember to check water ph after you add nutes and adjust accordingly.

this would be the complete FF line up. Are you using the trio….Grow Big, Big Bloom and Tiger Bloom plus calmag? Target 1000-1200 PPMs in soil 
Thank you for clearing that up, makes sense. Yes I am using the trio
