If I had your water and you were talking about hydro, I'd use about 1ml per gallon of magpro. Is it needed? Probably not, but I like the dose of magnesium and sulfur it brings to the table.
Clones? I can tell you that no matter what medium I'm using, I'd never 'raise the food' based on the number of weeks that have passed.

Thanks Hb I have been really learning a lot because of your journals, then whats a good ppm to start with from just rooted clones? I know DG is very strong stuff so I dont want to burn them to death

Maybe 150 ppm in dirt and 400ppm in hydro on the .7 scale?

That doesn't help me much. I'd say just watch your plants and feed them no more than a total of 3mls per gallon of grow or bloom or a combo of both. Cut that in half for small plants.
I use RO and promix. The only food the plants get are from me, that takes the guess work out of feeding as your spring water and soil will both be supplying minerals your plants can use.

im using this meter http://homeharvest.com/hydroponicectestmeters.htm how do i know which is .5 or .7?

Lerster, there are two different meters on that page, which are you going to get? The one I have is pretty much like the longer stick one (the first one on the page), but a different company. Though, the third one is cheaper and should still get the job done for you.
I got mine used from a dude off craigslist. I'd recommend checking that or amazon or something first cus you'll probably find a better price.
Just a thought.

I don't know, I don't use your soil or spring water. Even though that's not what I said to do in response to your last post, do what makes your plants happy.
I use protekt from start to finish at every watering, it balances the pH. Add it first to a gallon, then plant food. Use enough so it balances your final pH to the mid 6's.
I don't use magpro in the dirt. It's highly concentrated and you'd only need like 1/2ml per gallon if you'd need it at all. Bloom offers plenty of P and K and you're not using RO so you probably don't need it.

Hey Homebrewer,thanks alot for all the help with DG and ECs(ppms)
Your #s are right on for my plants,they're looking great & my ph never moves with DG.
Thanks again for doing all the work & posting it for us.

Homebrewer,
Thanks for all your work on this thread. I've read it twice (three times?
) -- once for fun, and again tonight while taking notes along the way.
I'm DONE with Fox Farm soil and nutes, and am thrilled to see that DynaGro has all the nutrients I'll need so I don't have to muck around with CalMag and a bunch of other unnecessary junk. I don't have enough time to mix up a batch of Super Soil and have it 'cooked' and ready to go by the time I start my next cycle, so I plan to use your soil method and then perhaps test it against an organic concentrate mix next time around.
Just a couple questions so I can get off on the right foot:
-I read you say a couple times that I won't need MagPro in Sunshine #4. Is that because there's enough Ca & Mg in Grow/Bloom?
-I also thought I saw you were using SS#4 early on, then I saw a mention of adding vermiculite to Mix #8 and most recently that you have switched to Promix? All of these are soilless, right? Inert, so that you can maintain absolute control on the nutrient intake?
-Also in that recent Promix reference, you mentioned RO water, which IIRC, you'd said you didn't use earlier. I don't use RO water at the moment, but it is pretty soft at around 40 PPMs. Any chance I'd need MagPro because of this, or am I just over-complicating things?
Thanks again for such a thorough investigation!

I use RO and don't use calmag ever and I don't have issues in promix or SS#4. Magpro is highly concentrated so you'd only need maybe .5mls per gallon? Too small a dose to justify measuring that out for each and every gallon.
They're all pretty much the same thing. I always add vermiculite and perlite to my dirt. And yes, they're all neutral mediums if-you-will. The only food my plants get are what I'm giving them. I don't like surprises.
My winter water at 330ppm caused me to switch to RO and once I saw how beautifully DG works with RO in both hydro and dirt, I just switched altogether. With RO in hydro, I think magpro is needed, or at least some mag additive whether it's 'sweet' or epsom salt or calmag.

Thanks for getting back to me HB.
Can you help me understand what's different about something like Promix vs. hydro RE:magnesium? Is it because it's more available at a higher pH, so there's already enough in the DG for soil plants?

Maybe I worded that wrong in that I didn't mean to imply the base formulas are short on magnesium. I should have said Magpro is helpful in hydro with RO water. I've only done one run with just bloom and protekt and the plants looked fine. I happen to like the sulfur content of Magpro so that's why I use it in hydro. Between hydro and promix, the needs of the plant should be pretty much the same, though I've noticed that in promix I need to use more 'grow' to keep the plants green during flower than in hydro. In dirt, I go about 50/50 with grow and bloom. In hydro, it's more like 30/70 with grow and bloom. My ratio of grow-to-bloom changes as the weeks progress in both dirt and hydro but in the dirt, I've already premixed grow and bloom in their concentrated form in a ratio that makes things easy for me.
