Trying coco for first time - Nutrient help?

[mellayella]

Hey guys, I'm soon to be starting my first coco grow and could do with some advice. Before I go any further I'll give info on my grow:

Lights: 300w platinum LED
Substrate: coco and perlite 75/25
Area: very small grow tent
Strain: auto blue amnesia by ministry of cannabis
Nutrients: cannazym, rhiZotonic, formulex, magna-cal+,liquid silicon, veg nutes, flower nutes.
Air intake/outtake: passive intake, adjustable extractor fan to regulate heat.
Humidity: not sure yet.

Okay so my main question is: how much magna-cal should I add to start off with? I've read it's common to get cal or mag deficiency in coco and also by using leds and i have both.
Also should I feed a light solution before seedling goes in?
Also should I feed feed flush or water with run off and flush every 2-4weeks? Do I add small doses to flush water? Someone please help I have 2 days!!

check out LEDRF grow journals and videos, His journal How I grow in Coco will explain pretty much everything to get you started. You can stop by my grow journal if you have any questions. Good luck on your journey. My journal is at Bottom of my post.

Try 2 ml/gal for tap and maybe 5 ml/gal for RO or similar. Some use more...some use less. I use 3-4 in tap. Wait until you start feeding in veg.

Probably not. Wait until you get a set of true leaves. You don't want to burn your babies. Try some Rapid Rooters next time.

Also should I feed feed flush or water with run off and flush every 2-4weeks? Do I add small doses to flush water? Someone please help I have 2 days!!

No, your runoff is waste. It's a 'drain to waste' system. Rule of thumb is to drain out about 10%.

How often you flush will depend on your nute buildup. If you know your PPM going in and the PPM of the runoff (coming out). you'll have a better idea of when to flush. Some people just routinely flush weekly but I prefer using my TDS meter.
