Not sure if you're replying to me.
I have a drain-to-waste 30 gallon reservoir on a timed feeding system, so yes, feed every time. What I vary is the duration of the feed. I do approximately 10 seconds every 2 hours during the day, but only 4-5 seconds after dark. I don't want the coco to 'dry out' during the night as it raises the feed concentration at the roots.
I didn't start out this way a few years ago. I would feed every 4-6 hours, but as the plants got bigger I fed more often. Last year I decided to just set schedule to every 2 hours from day 1, lengthening the feeding a bit as plants got bigger and started using more water. Since I use the runoff to feed lots of plants around the house, I don't feel like I'm wasting nutrients. Regardless of plant size, I try to end up with about a bucket of runoff every 24 hours - that should be enough to keep the roots stable.
By having nearly-continuous feeding, I don't think I need to make the nutrients more concentrated as there will always be some nutrients available. This grow seems better than ever, without even having burnt leaf tips. Super healthy looking plants, growing like weeds! In fact I should have flipped to 12 hours at 3 weeks (since seed germination) instead of 4. About 3 weeks in my pots in the tent, after a week in red solo cups as seedlings.
I go by the General Hydroponics 'medium' schedule, which includes a 1 week flush at the end. Specifically, I use the Floraseries 6-part feed chart here:
https://generalhydroponics.com/resources/flora-series-feedcharts/. I also add 2.5ml/gallon of Silica Blast, which I think makes stems thicker and stronger.
I urge you to find and read (at least my entries) in a thread I made 3 years ago here called 'Explosive Growth in Coco Coir', where I detail pretty much everything, and I have lots of pics. The biggest problem I faced was the growth rate being REALLY fast, and my plants outgrowing my tent during the flower stretch. I had to change tents in mid-flower for one that was 1 foot taller. (8 feet instead of 7). I'm almost in the same situation again as this crop really took off on me. I'm 1.5 weeks since flipping to 12 hours (from 18), and my plants are about halfway up the tent, before flower stretch.
Fortunately, I think, my new grow light may make it possible to have reasonable coverage as close as 6 inches from the canopy, though I suspect the light will be too strong then. At the beginning of this grow, my 5-year-old HLG led light died, and I had to quickly replace it. I ended up with a TLS 'light bar' system that spreads the lights right to the edges of my 4x4 tent. My HLG had the leds concentrated in the center, wanting 24 inches of clearance, minimum, for decent wide spread.
There is a huge difference in watering between coco coir and any kind of soil. Soil holds water, so overwatering drowns the roots. Roots need oxygen at night, so there needs to be some relief there.
On the other hand, coco coir drains so quickly that you almost cannot overwater. So you can feed almost constantly (somewhat like hydroponics) but NOT have too much nutrient concentration. Lots of nutrients at lower concentration means the plant always has food, but never too much, or too much water. There are some other differences, like needing to add Cal/mag, but if you follow the feed chart I use, plants will grow pretty much at the maximum rate they can under your lighting, temp, humidity and CO2 values.
now it comes pre broken & even washed it’s much easier.
