I've been running the dynagrow since I first read this journal. It's been about 6 weeks now that I've been using it in a RDWC setup.
For me, the mix seems really "hot". I have a group of 3 plants, about 5 weeks into flower that have been on dynagrow since mid veg. I have a sativa, indica, and a hybrid.
I started running my mix at 700 ppm, already way below the suggested feeding. I saw nute burn on the hybrid, and nitrogen overload on the indica.
The sativa looked 100% happy.
I've been dropping the levels even more, since I realized that I was seeing nute burn and not some deficiency. I'm now down to 375 ppm, and the hydrid is finally looking happy. It has some new white hairs popping out of the tops. The Indica has been really weak on the bud production, and looks overly green and leafy.
I was also seeing daily drops in PH from 5.9 to 4.9
I had better luck running my old GH, and yesterday I switched back to it.
Do you think the ammonia based nutes are my problem?

A few questions:

What ppm scale are you on?
Are you running all these plants out of the same res?
What is the ppm of your water?
What DG products are you using and how much of each are going into a gallon of water?
Are your strains from seed or clones?
If clones, have you grown them before?

I'm a bit of a newbie, but have been reading a bunch.
The meter I use is an aquapro AP-1, i'm pretty sure it's the .5 conversion

I am running these 3 plants out of the same res.

I am using RO water

I am using 5ml per gallon bloom
3 ml per gallon protekt
1 ml per gallon calmag
earlier in the bloom cycle I was using a little bit of grow with the bloom.
I'll mix a batch, and than water down till I like the ppm.

These are 3 clones I purchased from a dispensary, and my first time with them.

My room humidty is about 35% most of the time. It goes as hi as 50% when the plants transpire alot. They are using way more water now that I've dropped the ppm down, and helping to hold the humidity higher.
using 600 watts of HPS, about 18" over the girls.

700ppm on your scale is too high for a few of my strains. Try just under 600ppm on your scale.

Yeah, quit doing that. Feeding levels aren't 'one size fits all'.

That's not enough nitrogen for your plants. Use a minimum of 1ml of grow all the way though flower. Keep your ppms in check.
3 ml per gallon protekt
Click to expand...
Use 5mls/gallon
1 ml per gallon calmag

I have not found a need for calmag but I do use magpro with my RO water.

I mix grow and bloom all the way through.

Only experienced growers can get great results growing a plant for the first time. Not being familiar with the needs and tendencies of the strain can make the first run difficult. Learn from your mistakes.

Additional info: top your res off each day and make sure your ppm isn't getting out of control.

EDIT: GH is solid but Dynagro for me is out-yielding GH by ounces each and every time I use it. My dumpster strain which yielded '16 ounces like clockwork' off a 600 is now yielding 20 ounces. All my strains have seen a substantial increase but you need to have a pretty good understanding of what you're doing to fairly compare one line to the next. Use what works best for you but DG > GH all day long.

DSC01612dynagrowweek3.jpgI have another 2 plants still on dynagrow, at week 3 of flower. These have never been over 500 ppm, and are still looking good. They are a nice deep green, with fan leaves that are still flat. The single leaves at the tops are behaving oddly though, the leaves facing away from the light have downward curl. the leaves under the light, or facing the light are sticking out nice and straight. what could this be telling me? these have been at 375 ppm for a week now.

Homebrewer, thanks a bunch for your help.
I've become a caregiver for another Colorado cardholder, so I can grow another 3 plants in bloom. I think I'm going to give ebb and flow a try under one of the 600's. I've got all sorts of pumps, fittings and timers. I should be able to mimmick your concrete mixing tub set up, and grow in 6 in cubes, 6 to a tray. I hope you'll still be on rollitup to help me out!

I'm in flood and drain so I don't know if feeding levels are the same for both hydro methods. If anything, I would error on the light side if I were you and just monitor the plant's progress. Keep them healthy and they'll do what's ingrained in their DNA. Those plants look healthy at 3 weeks. Keep them that way and take notes on your feeding schedules (ie. how much grow and bloom at which week and how the plants are looking).

I'm subbing to this. I just recently changed over to Dynogrow line. I was running GH Lucas formula but noticed some deficiencies. I just like the simplicity of these nutes. Thanks hb for the awesome thread!

How much Magpro should I use in a recirc per gallon? Does this have both Calcium and Mag? I think I'm having some cal/mag issues.

You're not having cal/mag issues, you're overfeeding. The following is from your journal:

Alright I'm running the 2 week hydro feed schedule I found online which says 7.5ml of grow per gallon, 4ml of Pro tekt, and .5ml of magpro. Do you think this seems like a good regimen, or should I do something else???
Click to expand...
See post #390 of this thread.

I use RO water and use 2mls of magpro per gallon in flower only.

Alright. I was just going by the instructions. Thanks for the help. Also, if anyone wants to help me in my journal the link to it is in my sig.

Homebrewer. What is your ppm with that 3-5ml of grow per gallon?

hey homebrewer im looking into buyin nutrient ASAP. dynagrow seems perfect for my setup my only question is.
Ive got leftover nutrient from my last grow (by leftover i mean mostly full)
Ive got great white" root booster. B-52 from advanced nutrient. As well as silica blast, clearex from botanicare and Superthrive and Cal-mag
I plan on buying Dyna Grow, Bloom.
Do Should i reuse some of my older nutrient or buy pro-tekt and pro-mag (and attempt to sell leftover nutrient)

Ps my setup is an aeroponic setup with the white bars

When you're out of silica blast, go pick up some protekt and if you're using RO water, pick up some Magpro too. Calmag and superthrive can be helpful at times when used correctly but I don't use either of them in hydro, ever. Sell the other stuff.

Hey, Homebrewer, how do you decide to when your going to put your plants into flowering? I can't find any consistent info on this subject. Any info on this would be greatly appreciated.
