Dyna-Gro vs Advanced Nutrients Connoisseur (AK47 Grow)

I'm currently around 2 weeks into veg. Using ro water bought from store. 7.2 ph@0 ppm. 20 gal Rez. I first add protect at. 2 ml/gal mix then add enough dyna gro to reach 400ppm@.5 scale I believe around 2 to 3 ml/gal. Then ph to 5.5. I am growing in grow rocks 1 gal containers. Flood 4 x day for 15 min. (10min pump on 5min drain) I'm starting to have some deficiencies? Im not too experienced but I believe it might be calcium or magnesium def. would it be due to not using mag pro?

That's good news. How long does it take for nute burn to show? Because it seems like its progressing slowly. And the Rez has mainly stayed the same. But it's time for a Rez change. So no need for mag pro at this time or a 70/30 mix of ro water and tap water?keep everything the same but lower my ppm and higher ph a bit.

I don't use magpro until flower and then only like .5ml.

5.5 ph is pretty low. 5.8 is where ya want to be. I run 5.7-5.9.

what is your starting ppm before nutes with the 70/30 water mixture?

you need to add some kind of cal-mag when using r/o water

I would disagree with this. I just sent out a few reservoir samples for analysis which were taken on different days and at the end of the week there was plenty of cal and mag left for the plants. I should add that this res had no additional calcium or magnesium outside of what the base nutes supplied.

So no mag pro or cal mag? I will most definitely higher my ph and feed slightly less. 14 gal ro water@0ppm +6 gal tap@340ppm= 20gal @150ppm. Another ? For u pros. Do u add any h2o2 or anything similar to keep Rez clean?

Why use any tap water at all? Your water sucks, it's similar to mine which is why I use RO.

I did first week all ro water and I felt like the edges of the leaves were curling up and slightly yellow. That's why I thaught it was a magnesium def. switched to 70/30. New growth seemed better. But it looks like those burnt spots on the leaves were spreading to other old fan leaves. Which brings me to here. So dynagro grow has enough magnesium and calcium to run with ro water alone and not see any def?

Absolutely. Fix your pH and EC first and report back in a week or two.

It's been a week now new growth good. But the deficiency is spreading. Slowly. Ph at 5.8@ 350ppm(.5) image.jpg.
After 3 week veg i topped them at node 8 to practice cloning on my homemade ez cloner.
Lik going to give them 2 days to recover and then flip to 12/12. My question is I got the mag pro so no need for mixing water. From now on 19 gal ro water. But at what dosage do I add protect/mag pro/gro/bloom for the first week of flower. Total ppms for the upcoming weeks. No hydrogen peroxide or bleach? Keep floods at 4 x day for 15 min?image.jpgthats before topping
image.jpgThat's after topping
image.jpgThat's my clones. Any and all info/advise is highly appreciated.

I kinda disagree about dyna having enough cal-mag to support R/o water. My plants are MUCH healthier when using cal-mag than without.

i've found so far that in veg. magpro is not necessary.

in flower I am using just over half a ml/gallon

running 20/80 ww/ro

lots of calcium and iron in my ww.

I did not like the fol. pro in hydro for veg. Got a lot of weird ducksfooting and all around odd growth. I am mixing in half ml/gallon of it now just to use it up more than anything. balance of nute mix made up of gro.

they look pretty droopy to me. What size are those pots? What kind of medium you using? It kinda looks like some sorta rock but not that I am familiar with.

i only flood up to 2x a day and that is in 6" pots. Sometimes only1x a day.

i would for sure in 1 gallon pots. I run 10 inch netpots w/hydroton for my moms which are fairly close to the same size as yours and 1x aday is more than enough. Even when they get really big 1x is enough. the only time I need to flood 2x is when my room temps exceed 80f or if I put a strong fan right on em.

Try it and see.
