Hey guys, 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! ![](https://global.discourse-cdn.com/growingmarijuana/original/3X/4/c/4ca2a73a878ccad8b11475e688a33c6b3c189d03.jpeg) ---

It’s perfectly normal 👍👌 They will need more watering as they get older and bigger 😉 Stick to your schedule for now, and keep the good work by checking the moisture like you did , your babies gone a tell you when they are thirsty and need upgrape nutrients, if you notice a slow in growth, just put more nutrients (follow the schedule from GH) and every thing is gone a be good Ô and by the way, your plants are very healty looking 👍👌@LST ---
