Guest Posted April 1, 2022 Share Posted April 1, 2022 Emailed growers ark yesterday and they confirmed I won’t need to add any calmag with my water as long as I use feed at 4ml/l Link to comment Share on other sites More sharing options...
OddNut Posted April 1, 2022 Share Posted April 1, 2022 @NiallkThat’s a hell of a lot of feed to be giving. I’m pretty sure it will be way too strong at 4ml/l even in heavy flower. My last run I topped out at around 2.5m/l ish if I remember rightly 1 Link to comment Share on other sites More sharing options...

At 4ml/lt it keeps your ratio right for P & K uptake. You also need the higher K in mid to late flower to avoid "finger buds". If you're feeding below this and its mid flower, check the lower fan leaves for browning. I'll bet you find them, because more Mg is needed as they flower to a finish.
