I have a 3 week old seedling. 4th set of leaves. Using a Waterfarm (Recirculating hydro) ..
How many ml or what PPM level would be safe? GH states 5 to 7.5 ml on the feed chart which seems rather high..
I'm thinking cut that in half. Maybe 400-500 ppm or so.. Any thoughts?
I was using Lucas formula (500 ppm floranova bloom, at this stage) , but now abandoned that idea since I am getting some yellowing. I know that Lucas works, but why not just cough up the extra $ for an extra bottle of nutes..
