I'm starting 2 plants in 5 gallon fabric pots with the floraflex matrix system using jacks hydro nutrients.

My local shop told me to use promix hpcc instead of pure coco. Is that right?

How many times a day should they be fed and for how long? 3 times a day for 1 minute each cycle?

Only feed during lights on or does it matter?

Grow in whatever medium you are most familiar with so you arent introducing too many new variables at once. Jacks will work in either promix or pure coco.

I only feed during the day to avoid guttation in late flower that can contribute to bud rot. I use 3 gallons outdoor and feed in 1 minute bursts every couple hours until i see run off then let it dry back till the next morning. Lately we have had a couple months of non-stop rain, so i have had to back off feeding as often.
