Why ?I soak my seedlings rockwool cubes in cal-mag with no issues at all
I grow Under LED and it gets in the plants system from the go and I have very soft water and flowering gets rusty spots without it.Why ?
Issues? what is the upside?
no I haven't added any , but read about it somewheremost calmag has nitrogen along with it. I use RO water, and dont worry about calmag on a seedling for quite a while. But if you did add it, I would let the amount of nitrogen you're possibly adding be your guide.
Depending on your medium. If you're using coco or rockwool, yes. If you're using amended soil or potting soil (organic or not) there's going to be nutrients in it already, and you shouldn't need to feed it for a while.Seedlings?
Or cuttings?
Seedlings have colyton leaves. The very first ones you see. Theyre round. Those have a purpose, which is to supply the seedling with nutrients. They have everything the seedling needs, regardless of whether or not you use RO water. Once they turn brown they have been sucked dry and it is time to start feeding the seedlngs nutes.
Cuttings... theyre mature and need food right after they root up.
True, but the OP said promix, which is inert.Depending on your medium. If you're using coco or rockwool, yes. If you're using amended soil or potting soil (organic or not) there's going to be nutrients in it already, and you shouldn't need to feed it for a while.
I just re-read the thread and he doesn't mention what his medium is. And there are several different kinds of promix, a couple of which are inert, but the flowering plant potting soil is heavy on the nutrients (possibly enough to burn weed), and the herb & vegetable potting mix which I use has enough nutrients to feed an indica for more than a month (there seems to be enough nitrogen in it for sativas to react badly).True, but the OP said promix, which is inert.
Oops.... i musta confused another thread.I just re-read the thread and he doesn't mention what his medium is.
