Cocoab Posted March 3 Share Posted March 3 Hi gents. can anyone with soft water recommend a coco base feed that’s been tried and tested with 0ec tap water. Trying to keep it simple. Ideally not a soft water specific feed as I’ve used one in the past and still had to add calmag at full strength. Any help much appreciated. Thanks!

The Green Manalishi Posted March 3 Share Posted March 3 I’m got very soft water, 0ec and I’m a big advocate for the Dutch pro so/ro nutes, if your having calmag issues with your feed, then I would look at your environment, growing in lower temperatures and especially with a cold root zone will definitely give you issues, I would check these first before looking at feed.

I’ve tried everything mate. Usually get the deficiency sorted in early veg. They look good nice and green until mid flower then the rust spots start. Are you in coco as well bud?

The Green Manalishi Posted March 3 Share Posted March 3 Im in coco bud, how much are you feeding when they start showing? Link to comment Share on other sites More sharing options...
Cocoab Posted March 3 Author Share Posted March 3 1 minute ago, The Green Manalishi said: Im in coco bud, how much are you feeding when they start showing? feeding 1.6ec with water buffered to .4 with calmag. 28/23 degrees 55% humidity. In 4l pots so don’t know if that would have anything to do with it but they’re fed 3 or 4 times a day with plenty run off. Link to comment Share on other sites More sharing options...
The Green Manalishi Posted March 3 Share Posted March 3 Just now, Cocoab said: 28/23 degrees Do you have a heat mat under your pots? at 23c you will find that the root zone temperature is a lot lower than your air temperature, and canna likes warm roots, it might be taking to long for the coco to properly warm up causing a lock out, if you can get a constanty warm root zone, your plants will love it. 1 Link to comment Share on other sites More sharing options...

I’ll try that. I’ll give Dutch pro a blast on the next run as well heard good things about it. What would ec would you normally top out in full flower with Dutch pro 1.6/1.8? 1 Link to comment Share on other sites More sharing options...

stummer Posted March 3 Share Posted March 3 So with advance nutes perfect ph, if you use RO water you still need to add cal mag? The nutes alone are not enough? Or would it be okay to mix some tap water to bring the ec up to say 0.4 and start from there? Been considering going over to ph perfect nutes. It’s just the slowness of filling with ro water that puts me off a little Link to comment Share on other sites More sharing options...
Herbal Kint Posted March 3 Share Posted March 3 Am not in UK but never had a need for cal mag with those nutes,you can pick a bottle just to have your mind at ease but i think it will stay on shelf. I dont use RO water,water ec is 0.6. Rootgrow(any brand)plus advanced coco AB is enough to go over g/w here. I havent tried rest of their range as list is endless Link to comment Share on other sites More sharing options...
