Having trouble with my plants. The first grow is Girl scout cookies Auto. Everything looked good until week 6 then some leaves started changing color to yellow browm. In a 5 gal pot watering 1l per pot per day feeding twice a week with grow big, big bloom tiger bloom and cal mag.
Calmag shouldn't be given at every feed. Every ten days is sufficient.
Are you watering to a runoff each time & what is the ph of this ?
I would just water with ph 6.2 to 6.5 & check the run off as I think you have nutrient lockout.
Remember your growing an auto & they can't take full feeds like photoperiod plants. Start a diary & goodluck
