That's the driest Fox Farm soil I've ever seen. Usually they look heavy/dense/wet. What you're feeding is NPK ratio 1.31-1-1.17. That's reasonable. 530/669ppm. Seems a little strong. But, maybe that's how those nutrients are supposed to work. (I've read conflicting stories about Ocean Forest and Happy Frog being hotter than the other. If HF is the hot one, it seems like what you're feeding would be too much.).The soil is Fox Farm Happy Frog, I'm feeding them 3tsp grow big + 2tbs big bloom per gal, I meter the soil, and when it's dry I water and let 20% run off. I only do the nutes ever other watering. Now my Ph is a little high right now because I accidentally grabbed the wrong water and its Ph is 7.3.
I've never grown with Fox Farm anything. Maybe someone else can guide you. I try to help based upon what I read. I thought consensus was that HF was less nutes, and you'd feed sooner. OF is more nutes, more risk of feeding too soon. (But, I've read it the other way around too. I don't think they publish anything on their bags about this.).I was wondering if I might be over feeding especially with such a rich, nutrient soil.
The spots are what I'm worried about.
Typically, water should have some ppms (ideally 100-200) which would include some Mg and Ca. maybe that's the problem. Distilled has nothing. You could add 1g each gypsum & epsom salt to a gallon. That would add 61ppm Ca & 26ppm mg. (And, 83ppm sulfur). That would be a good starting point. Or, people use "calmag" products to do that too.I'm using distilled water, PH 6.0 to 6.5 I don't know what the PPM's are.
