You wouldn't need calmag if the nutrient companies didn't purposely leave it out so they can sell you another bottle of stuff. There is absolutely no reason that coco specific nutrients don't have enough in their base. I grow in coco and have never had the need for calmag because the cheap base nutrients I use contain everything the plant needs. These are not cannabis specific nutrients but formulated for hydro to grow all kinds of plants. Cannabis specific nutrients are just overpriced marketing nonsense. By slapping the word "Big" "Giant" "Power" on the label and targeting cannabis growers they can sell the same fertilizer for 5 times what they could if they just sold it as Plant Food which is what it is.
I also don't understand mixing hydroton with coco. Straight coco or coco/perlite is better. In fact I stopped adding perlite a long time ago and grow in straight coco. Plants thrive in straight coco.
I'd bump the pH up to 6 and keep it there myself. I also wouldn't let it dry out like it is in those pictures. Although unlike many I don't believe excessive amounts of runoff are needed. In fact I use Blumats and there is no runoff. So much of what's out there regarding growing in coco I don't follow and never have any issues. I don't water until runoff because the Blumats keep the coco consistently damp and I don't use calmag because I feed a nutrient that contains all of that. I have very little faith in any cannabis growing website as I don't follow their guidelines and have healthy plants from start to finish while others follow those guidelines and have issues all throughout their grow and end up checking runoff and chasing pH and nutrient issues. It's a damn plant. It doesn't require all this hocus pocus floating around on the internet.
sir , that was absolutely beautiful ( me clapping )that is one of the best answers I have seen. you are so bang on with 4he nutrient. I have made my own since 1989

( me clapping) sir , that is probably the best answer and info I have seen on several different sites.so simple. nutrient is cheap. no rocket science. standard agricultural product. a simple inexpensive 12 mineral minimum product with N P K Ca Mg S Fe Mn B Z Cu Mo
get an ingredient list as is normal on every other plant because weed is just another agricultural crop like any other and is not special...bravo ( me clapping again)
so the only 5hjng I would ad ( if I missed seeing that u already said it) is 5o keep watch on 6our input EC as well as your runoff.
the medium EC should 4un between 25 to 50% more than feed ec
so f3ed ec 800
waste ec is 1000 to do 1200 .
if your ex is more than double input you will most likely experience nutrient lockup and salt burn.
the easy fix is to flush 1/2 ststrength solution though 5h3 medium until waste or runoff is back down around 1000 then continue watering as normal with a 15% over flow each watering to keep medium EC down.
The solution to ANY nutrient disorder , toxicity , or deficiency, the solution is th4 same. flush out old solution with new Solution until EC of waste is 800 to 1200 ec .
i have made my own nutrient since 1989 . I buy in 25kg bags of individual nutrient salts and mix my own formulas. can post them too if wanted. costs me about 7 to 10$ for 20 liter 100: 1 concentrate. ( 20 l a and 20 l b ) the only reason 5here is 2 part formula is to keep the concentrated calcium and phosphorus way from each other so they do not combine 5o form water insoluble calcium phosphate. calcium nitrate is in the A and monopotassium phosphate in the B
no supplements either .
any way my friend good job. I think I will follow you.
truth is when I started reading I though I wrote it until about half way through. read my responses 5lto most issues and they are the same lol
Result was 11oz, not great but always something, I learned a lot from my mistakes and will improve a lot with the next one. Thank you Myke for all your help, I wouldn't have done it without you.
