KC Posted March 7 Share Posted March 7 As far as I can remember Calmag wasn't a thing, I've only heard of it in recent years. Everyone seemed to be growing cannabis just fine before we had it. Ok if it helps you now then why not use it but we did fine before it came about. 4 Link to comment Share on other sites More sharing options...

Chloramine may be a different story, but I just pretend that doesn't exist . Edited March 7 by MindSoup 3 Link to comment Share on other sites More sharing options...
ratdog Posted March 7 Share Posted March 7 (edited) 3 hours ago, sweettooth said: wasn’t criticising anyone Ratdog sorry mate, wasn't aimed at you, just those who preach against its use Quote only time i saw deficiencies was when i was lazy and didn’t ph which led me to me other question about ph downs and there effect on calcium and magnesium which may also be a contributing factor as using phosphorus based ph downs may remove some of the useable CA and MG i've not had to adjust my feed ph at all using ionic, but even with 1ml of calmag i'm still using 85ml/10ltr of bloom to get to 1.7-1.8, that's probably why it's so cheap, £30 for 5ltr Edited March 7 by ratdog Link to comment Share on other sites More sharing options...

Goohfy Posted March 16 Share Posted March 16 Some of my plants need it some are fine without and I have a ph 7.4 most days not much fluctuations so no its not snake oil read the plant if it needs it let em have it.Mainly needed with crosses with more sativa in I couldn’t tell you why.And a bit off topic but get some decent silicone and a fan and you won’t need loads of fishing line to hold the buds up done.peace Goohfy.

sweettooth Posted June 10 Author Share Posted June 10 In contrast to my previous statements, I have started giving plants a 1ml/L dose during switch over from veg to flower and up to week 3 I think some people see it as a "fix all" and its not, sort your feed and environment first and then add when the plants need it (reading your plants is a must) Link to comment Share on other sites More sharing options...

Lux_Interior Posted June 10 Share Posted June 10 I used CalMag after switching to Coco from compost but I have changed to a new nutrient and I don't seem to need it anymore. I guess its a matter of horses for courses. Nutes/Substrates, etc. Link to comment Share on other sites More sharing options...
lambrettats1 Posted July 10 Share Posted July 10 I use canna coco along with 10ml cal mag in an 18L container. I know that if i do not add that calmag i have deficiencies, this is because my water is soft simple as that. Link to comment Share on other sites More sharing options...
JamieThePainter Posted July 26 Share Posted July 26 I use soft water and haven't had any Mag/Cal deficiencies, so I'm not sure it's quite as simple as that. 1 Link to comment Share on other sites More sharing options...
