This is my first grow with coco/perlite and I’m a little confused about feeding and watering with this particular medium.
Here’s my setup;
I’m currently growing 3 plants in 5 gallon smart pots with a 50/50 mix of coco/perlite.
It’s day 18 veg and they’re under a 400w MH in a 4x4 tent. Humidity is 60% and temps stay around mid 70s.
Watering PPM: 136
Feeding PPM: 425
Water pH: 5.8
Nutes: FloraTrio + Ca-Mg
Here’s my question; I have been watering 2 gallons per plant every 7 days. My regimen is FWFW, so the plants get fed their base nutrients every other week. Do I need to feed them every week? If I feed every week, this means I’ll have to water every 3-4 days instead of the usual 7 days. The reason I wait 7 days is because that’s when the medium actually begins to feel dry. If I wait any less than 7 days, the medium feels soaked and I don’t water because I’m afraid to overwater.
Is it normal to wait 7 days in between waterings?
Can I just add in an extra watering during the week in order to avoid salt build up in the medium?
Any responses much appreciated!
