MonkeyBlazed Posted May 12, 2022 Share Posted May 12, 2022 What about using calcium nitrate then chelating it with certain amino acids for better up take. You can buy mag thats chelated as well. Just a thought. Link to comment Share on other sites More sharing options...
Guest Posted May 12, 2022 Share Posted May 12, 2022 Try growers ark mate, I was ready to throw the towel in for this exact reason constant cal/mag deficiency’s even when adding plenty cal mag. Sent a sample of my water to growers ark and it came back crazy soft calcium 6 magnesium 0. Switched to coco and the sw nutrients what a difference.

mysticriver Posted May 13, 2022 Author Share Posted May 13, 2022 its just suprising that no-one has come up with a definitive answer by now about where the calmag strength should be in coco under 24hr led lighting conditions to prevent these Ca problems mystic Link to comment Share on other sites More sharing options...

ratdog Posted May 13, 2022 Share Posted May 13, 2022 i think you should definitely get some soft water nutes, either GA, or terra aquatica tripart, or even growth technology, i'm going to speak to ian from GT on monday about what he thinks, he's recommenced formulex or green haze so far, but he should have some good insight to the best for my area as the company is only 7 miles away, and they have been doing this shit for over 22 years that i know of. 1 Link to comment Share on other sites More sharing options...

ratdog Posted May 13, 2022 Share Posted May 13, 2022 i think your problem is your water, not 24 hour lighting mate, many people here grow autos and don't get that issue are you running leds? 1 Link to comment Share on other sites More sharing options...
mysticriver Posted May 14, 2022 Author Share Posted May 14, 2022 (edited) 19 hours ago, ratdog said: are you running leds? yes. 2 x ~480W I 'turned off' the co2 last night, by closing both of the ventilation flaps and giving the tent a 125mm fresh air feed from outside so the co2 will half, down from 900ppm+ thats the only other thing I can think of right now, cos the plants are otherwise growing well. it might be having an adverse effect. in veg at least. mystic Edited May 14, 2022 by mysticriver Link to comment Share on other sites More sharing options...
ratdog Posted May 14, 2022 Share Posted May 14, 2022 so you have lots of light and co2, you are driving them hard mate, i would seriously consider getting decent soft water nute Link to comment Share on other sites More sharing options...
