I'm about to give the girls there first feed of h3ads ratio these are the girls before the feed of...
2 grams Epsom
12 ml micra
18 ml bloom
10 litres of tap water
Ph 5.8
ppm 700 @.5
I will be uploading pictures every day for 1 week for people to see the progress & help if they feel that they can.20170502_153603.jpg 20170502_153557.jpg 20170502_153551.jpg 20170502_153540.jpg 20170502_153532.jpg 20170502_153527.jpg

When I hit the 6 week mark of flowering. I reduce my nutrient strength to 200 ppms and slowly taper my nutes' to plain tap on the last watering before harvest.
I was doing some trials on anthocyanin heavy strains to see if I could figure out the process of bringing out the coloring, what different nutrient formulas do for the production of the pigments. This plant was feed plain water for the final 4 weeks of flowering, and as you can see it did ok with no nutrients that final 4 weeks.DSCN0694.JPG
That is in a 5.5" square pot of coir.

I grow in coco/perlite hempy pots. I've had solid success with H3ads mix of 6ml micro and 9ml bloom throughout veg and flower. I mix with 3ml of ph down and 1 gallon of tapwater. Never needed calmag or epsom salts. My ppm is about 840-860 if I remember right. Ph is generally in 5.7-5.8 range. I guess I've got something in the water that my plants use. I feel pretty fortunate that it works out good for me. I've watched people pull their hair out trying to find a good solution that works for them.

seems like your idea worked! cool colors on that one.

i've got about 2 weeks left and i'm going to experiment with just potassium sulfate as my nutes. skip the N and P altogether.

i think people take for granted that the water you use is as important as anything else in the grow equation. i've been trying to ween myself off RO and use my well water. RO was nice in that the only thing in it is what you put in it.

The whole reason why i use RO is because I want to know what is exactly in my nutrient profile.
This is what I use.DSCN0737.JPG for veg.
And this for flower DSCN0738.JPG
That's it and nothing else besides RO water

What was simple was the CNS-17 bloom, veg to finish with it with only using hydroplex as a booster week 3 to 6. 7 ml of the bloom and 2.5 ml of hydroplex. 2 bottles only.

After looking in to NPK ratios lol ' I've decided to drop the Epsom from 2grams to 1gram, every other feed
I'm sure the 61mg/l in my tap water is plenty along with 97mg/l in the 6/9 ratio giving me 158mg/l
There is also 9.8mg/l of magnesium in there to so' 41mg/l + 9.8mg/l is 51mg/l
Giving me a overall ratio of nutrients of.....
N=101
P=60
K=105
Mg=51
Ca=158
S=67.........TOTAL 542

If I understand correctly , I'm a little high in CA and and N ?
if it doesn't work out , I will buy some distilled water from the supermarket and mix a 50/50 with my tap water and bring the ppm sown to 100ppm and see how the girls like it then?

Day 28 12/12
Day 15 flower20170502_153557.jpg 20170503_065458.jpg20170503_170229.jpg

They look a little high in N. Yes, but look healthy otherwise. It would be nice to take about 35 ppm of N and distribute that out between the P&K and get rid of 60 ppm of the Cal.

Could you recommend a good pk booster to cover the pk side of things?
I've been looking at the numbers and I might be able to go with 6/9 plus my 200ppm tap water at a diluted rate of 1.5gal instead of 1gal 'for a 75% strength solution? The number's would be close to.
N=75
P=45
K=79
MG=38
CA=118
S=38 TOTAL (392)PPM @.5
P, NEEDS 15 PPM
K, NEEDS 20 PPM
MG, could do with a boost as well 'maybe 20ppm for a TOTAL 447ppm , you think this is OK? I have Epsom I can play with to get the ratio down but' I'm stuck on a PK booster that just has phosphorus & potassium.
I did buy GHE bio-bloom booster ' the little green 30ml bottle that's SUPER expensive lol, there chart said to use throughout flowering at 2ml/gal but' no element ratio to analyse?? GHE don't seem to do a PK booster for there flora line?

Day 68, from germination
Day 29, 12/12
Day 16, flower.

Today will be the 4th feed of 6/9 ratio and' still a problem with N I think in the last 2 pics of the widow?
The top 2 pics of the sour d are starting to fade lighting green again?
Overall the plants are growing nicely despite the imbalance of nutrients

I'd go back to the ratio in post 32. that is almost identical to H3AD except i would use all distilled water which would drop your Ca significantly. keep the 1g/gal Epsom would put your Mg back up closer to 67 target value.

as for you PK booster question, i wouldn't bother with it. i'd use the H3AD formula until the end. just as with Lucas, it is designed so you don't need any additives. get this grow done and see how they come out and on the next grow, try the PK boost and see if it makes a difference. P is more for early bloom anyway which you are past. and if i remember correctly, coco has K in it naturally.

I've got no choice this run to use my tapwater that's 200ppm, I want to keep my ppm low in the 500 range and not up in the high 700/800 range I'm getting now?
Also ' I've just descoverd how these ratios&npk levels work so I'm getting a little excited in my little old bubble world 'dreaming if finding the perfect ratio that will give me the happiest plants that will rewArd a ilegal UK gorilla grower like me with the DANK EVERYTIME BABY!!!lol

On a more serious note, I thought maybe dealing with my high CA of 158ppm buy diluting the sulution & add a PK boost to make up the difference in p&K?

if you are stuck with tap, that's what you'll have to stick with! lol. i don't think the extra Ca will make too much difference but i would stick with the 6/9 + 1g to keep the P and K and Mg levels up where they need to be.

if you can work on a RO system for your next grow, i'd go for it. then when you do H3AD, you'll be dead nuts on to what he came up with.


if i were you, i'd just keep to basics. the plants look healthy as hell, just too green, but i think the end results will be perfect. thousands of growers have used H3AD if that makes you feel better. lol.
