I try to keep things constant and I look for a output values that's slightly over my input in EC.Yeah I get you buddy!
My Ph only from Blue Lab is likely very close to perfect. Only a mknth late on calibration!
But what are you looking for on output? A drop in Ph, PPM and EC? Or somethings table in and out?
Of course we look to the plant for our lead - but what makes you feel comfortable? Honest question!
I remember the first grow we used these trays it going in at 5.8 and coming out at 4.4 but we ran higher EC then.
Say I'm aiming for 1.0 EC in the pots and I feed them 0.6 EC from the reservoir and in veg runoff comes out 0.9 EC feeding two times a day. If I then switch to flower you will see EC start declining on the runoff.
Instead of increasing nutrient strength I then aim to increase feeding frequency to combat a downward and upward swing in EC and pH between feedings.
I aim to have my output within 0.3 EC points of my input. If I feed 0.7 I want 1.0 EC on the runoff. If that start to add up way above range I start decreasing strength on the feed.
When it comes to the plant itself I mostly look on leaf tips and newly formed growth and leaf shade at different stages of growth ie small leaves, big leaves, amount of gloss etc.
