Yes, use CaliMagic every watering with RO to avoid micro nutrient deficiency.
Sounds like you're using soil as simply a medium for adding ferts. I won't derail this nice thread beyond this post, but if the plant and microbes were allowed to control the soil, the pH measuring, deficiency conversations, etc all go away. Build the soil properly from the start, and most just add water. Maybe some castings as you go.
You can use RO water, which is essentially rain water
Again, sorry for the intrusion.
What hydro nutes? Calmag? I didn't realize calmag is hydro only if that's what you're saying. I've see plenty of people add calmag to RO water in soil grows. I did put dolomite lime in my soil and used plain water up until flower.If you want to use hydro nutes, stop using soil and grow hydroponics correctly.
Okay cool, I'm thinking its just that, I'm not giving it enough calcium. Not salt build up or lock out.Shit man Just saw you asked me a question. Cal mag should be going with the nutes. I always adjusted feed schedules to levels so that I feed every watering using RO. Before that using tap water and feeding every other watering. You will be fine using it with in between waterings too.
