Dyna-Gro Experiment

Theophilus said:

Homebrewer said to go with 1/2 tsp per gallon for plants that are IN flower. Half of that for plants that are "still in veg" would be 1/4 tsp per gallon. He knows what he is talking about. According to what you just said, you are doubling the rate that he just suggested you use, in case you missed that. Just trying to be helpful.

I understand that and I was going to, and tried, to use 1/4 tsp per gallon but its only like 160 ppm or so. I bumped it up to 1/2 and fed because 160 ppm doesn't seem like it would do anything. The next and last time I fed I bumped it to dyna-gro's recommended 1tsp/gal for correcting deficiencies. One of my plants is starting to show the small rust spots of a calcium deficiency.
They also recommend 2-3 tsp for "hydroponic production" which I would never try but I also don't see how 1 tsp/gal (500 ppm) is going to burn my plants.
Like I said I will back it down to 1/2 tsp/gal and go from there. I will keep you guys posted. I respect @homebrewer and respect his opinions, I do. But this is a test so that is what I am doing... Running it through its paces.

FWIW, I "build up" to 3ml/gal of FP in veg and 5ml/gal in flower. No signs of any burn ever and nice green leaves. I also use protekt at about 2 ml/gal.

Still running...

1/2 tsp/gal dyna gro 7-9-5
1/4 tsp/gal calimagic
1/4 tsp/gal pro tekt
1/8 tsp/gal kln
pH down to around 5.8

In addition to FP, I'll use a small amount of protekt. It's not needed but it's beneficial. I've also been experimenting with the use of floralicious plus in promix just during flowering.

bro.is AN big bud powder in pro mix doable? ty ty

yo dirty, how are you liking the 7-9-5? i bought a gallon yesterday and am going to give it a try in a couple rooms. i recently bought like 10 liters of h and g aqua flakes and have been really disappointed thus far. everywhere i looked people seemed to be raving about the stuff saying it works great in dwc, coco, pro mix. i was using some old advanced sensi grow on all my coco plants with great results and as soon as i switched to aqua flakes things started looking bad. i messed with the ec a little but still haven't been able to get them looking how i want them. so i bought the dyna gro grow7-9-5 and am going to see what it does. thrive alive b1 and 7 9 5.

How much of each part are you feeding per gallon?

for the aqua flakes i started out at equal amounts 5ml per gallon. went up to 6mls, then 7mls per gallon. tried adding a little cal mag. backed down to 6ml gallon. the plants aren't a disaster or anything, just exhibiting deficiencies. they seem pale but have some clawing going on. magnesium issue maybe? they loved the 5 year old advanced sensi grow at 6mls per gallon but i ran out. coco/perlite drain to waste. i'd take any pointers any of you experienced coco guys have to offer. this is only my third cycle in this medium. i liked the numbers for the dyna gro grow so trying a little side by side.

i actually liked the foliage pros npk better but opted for the dg grow because i thought it might perform better through flower.

I know H&G's feeding schedule probably says otherwise but you could have cut those numbers in half and still been more than fine. I promise that you're not seeing deficiencies but rather burn and lockout.

The reason Sensi worked at 6mls/gal is because it's just over half as concentrated as Aqua Flakes. When you switched to 6-7ml/gal of Aqua Flakes you were basically doubling the amount of food that you were feeding your plants.

DG's products are even more potent than H&G's bottles so you need to be even more careful there.

the sensi grow i was using was the old version so i don't think it was as watered down as what their current version may be. 6ml of hg was getting me to around .9ec while 6ml of AN was like .85. i fed with the DG yesterday at about 3ml per gallon and 1ml of thrive alive red to get .75 ec. they were looking nice and perky this morning so we'll see. i started feeding one of my clones in dwc the aqua flakes so hopefully i can use that shit up in dwc with some good results. so are you getting better weight or healthier plants using the foliage pro as opposed to the DG grow?

In promix/coco/dirt, Foliage Pro from start to finish yields slightly better than Grow but the 'average' grower might not actually notice a difference between the two. IMO, you cannot go wrong with either of those two bottles.

Nice I'm using foliage pro. I'm hitting 12/12 this weekend. Lovin dyna. Check out my plants so far in veg in the grow journal sec hombrewer. Props for the dyna tips. Your posts led me the way of dyna.

"I've noticed this in my own garden when I've tried to feed my plants what I want them to eat rather than feeding them what they want to eat" < thats a good one HB

did 2 grow dyna foliage bloom...swithin AN grow bloom micro....gonna see for myself the difference....GROW BIG

Also, when was the last time you calibrated your pen? For me, 6mls of each Aqua Flakes part yielded an EC of 1.5. Your numbers for Sensi seem accurate though as 6mls of each part would equal 0.9 EC.

I'm pretty pleased with Dyna Grow's 7-9-5 right now. Like @homebrewer said already, its potent stuff though so back it way down. I want to try the foliage pro but looks like I'll have to order it online as my local shop only carries the grow 7-9-5 but I would probably still flower with the 7-9-5 and veg with the foliage pro.

Running these ladies with 1/2 tsp per gallon.

Only thing I really have to add is calmag with the dyna gro. Some strains are obviously different and some of my plant were showing slight calcium deficiencies. I also add pro tekt but going to try not adding it and see if my reservoir pH stays a little more stable. I have a theory that the pro tekt is dropping out after a day or so and the pH drops with it. Just a theory I'm going to test.

As you can see by the picture I'm also running a test to flower under MH lights all the way through. I tried this before but that grow experienced a lot of other problems.

i just went back there and surgically measured out 6ml of a and b and it brought one gallon of my well water to 1.01 ec. it must have been 5ml that had me close to .9. maybe i got a weak batch? my meter seems to be working like it always has. my water starts at around .25ec. none the less im gonna run the dg grow with these particular coco plants and use the hg aqua flakes in the rdwc. i think the k in the aquaflakes might be way high for coco. have you used aquaflakes in coco with good results?

When I tested Aqua Flakes, it was in my ghetto flood and drain tables. I've only ever used DG in coco.

HB,

I noticed in another thread your comment about Sativa. I planted from 20 yr old seed, a dozen pure sativa plants at the beginning of July. It's now nine weeks later and they are doing fine, but I have stressed them to keep the height down. One very large one showed male with little bunches of grape-like clusters last Friday. The rest so far look like females w/ just a hint of pre-flowers.

You mention the long flowering cycle of Sativa and I've seen others talk about 100 days or more in flower to harvest. That means I am looking at the middle of January at the earliest. The climate in Pennsylvania will have long killed off the plants by then. Aside from taking cuttings and making clones, which I have had very poor luck doing (out of 50 more only one cutting showed rootlets and that one was an Air layered lower branch. None that I severed from the plants have shown any inclination to root.

If I were to dig up several of them to get most of the root ball, and put them in my grow room by the end of October, do you think that would be the kind of stress that would make them all but useless?

I am still taking cuttings and trying to get more clones but I don't yet know how they are going to turn out. Do you take cuttings of your sativa and if so, how do you do it?

Any reply would be very helpful.
