Growing various lettuce in Masterblend, using air stones . The leaves of lettuce feel 'gritty' and taste is off a bit, almost a chemical taste. Are we supposed to remove nutrients and use just water for a bit before harvesting?
I will reduce the nutes...
do you mean Ppm 1400
Not ec
Which would be 2.8ec
no I mean EC. have you run 2.8 ec? That is really high and can easily cause nutrient burn or lockout.
i don't have a pen im getting on ive only measured ph and ppm...
I run my lettuce kale etc at 400-500ppm
Ppm is half so yes 400 500 is good on low side. 900 1000 ppm is high
how do they do that in the field? I don't even harvest but constantly graze whilst still growing.
hmm. I just thought that was proper so you have better tastes
The plant doesnt put minerals persay. It makes it own and stores them in the leafs
