Starting a coco grow for the first time , I have decided to use floranova for my nutes and I get the ppm usage for them at diff stages of growth. I will also be using super thrive and a Silica Lang with pk13/14 when it’s needed during flower , What I don’t get is when I use cal mag, any help on the proper usage of these would be of great help Edit : I will be using r/o water Sent from my iPhone using Tapatalk
Some people only use it when the problem occurs i just use it in every feed Sent from my SM-G950F using Tapatalk
Feed to run off 20 % fn is salty but a great Nute it has cal mag in it I still ad 1/2 ml per gallon . I haven’t went over 800 ppm it’s stronger than you think I’m in the end of flower feeding 500 ppm twice a day .
So what would u suggest as a base ml per gallon ratio for the duration of the grow ? And I assume I would add cal mag last to my ppm reading for my feeding ? Sent from my iPhone using Tapatalk
Silica first then calmag then base nutes . I start 200ppm for seedlings then go up as they grow if your tips yellow it’s the first sign of Nute burn cut back the nutes .
If you use r/o water you will definitely need cal/mag. Silica first, then cal/mag, then base nutes. I won't use anything but FloraNova - you made a good choice. I start with 2ml of FN from the day they sprout, increase as they grow - 5ml being max. Good luck. I follow GH's feeding chart for drain to waste hydroponics.
