All depends on the overall ppm of your solution. In the height of flowering with autos your ppm should be about 600-650 ppm on the 500 scale i think....dont quote me.I didn't know that about Nitrogen. I just noticed the NPK of Fish Mix (during veg) is 5-1-4 & Grow (during flowering) is 4-3-6. I'm guessing that's relatively high Nitrogen to use at full dosage (or regularly) during flowering?
Light Mix has a charge of nutes that does about 10 days. So I don't start to feed nutrients until the second set of leaves have formed
This is them as of 10 minutes ago. So I'll give them the bare minimum Nitrogen as possible during flowering
The water I use is about 220ppm with nothing added. The feed Im giving right now keeps it around 700, id rather feed light than heavy. Keeps problems to a minimum. During veg i think its suppose to be a little less. But I am unsure about that one. I rarely feed at all during veg since I only grow photoperiod plants.
