there plenty of options, im going to recommmend what im familiar with but that doesnt mean other brands arent good
since your currently using a 1 part formula
if you want something that is super easy to use a 1 part formula the general hydroponics floragrow for veg and floranova for flower
is super easy

full strength

floragrow (for veg)
1.5ml/liter
plus add 0.5 grams of Epsom salt per 4 liters

floranova (for flower)
2ml/liter max

Unfortunately I'm very limited to what I can get here. However, I can get HESI - which seems to have some great reviews.

RO definitely isn't going to hurt and a water analysis is very good to do and they are usually cheap. 20-40 bucks. Local farmers can usually tell you were to go.

do you have access to dry salt fertilizers?

calcium nitrate
monopotassium phosphate
potassium sulfate
Epsom salt
and peters s.t.e.m. micro nutes or some brand of micro nutes?

Unfortunately not. I live in a 3rd World Country. I have to order everything by mail that takes 2 weeks to arrive.

I could possible get some epsom salt. Will they help?

I think you might be right about the EC. I'm keeping my EC to 1.6 at the moment. Ionic's recommended dose is 1.5.

However, I just read this.

"Lets start with the small print on the bottles. What many do not know: the recommended EC value is based on osmosis water with an EC of 0,0!"

https://www.rollitup.org/t/ec-by-joe-camel.928508/#post-13181569


My water is 200pm, around EC .333 - From what this guy says my final EC should be 1.5-.333 so 1.16. I'll go tonight when the lights are on and reduce the solution to 1.16 and go from there.

How long do you think the plants will take to show any signs of improvement? A week?

now that I know you have limited access I will take another look at what you've got

keep offering options you have available
if we don't find anything better stick with what you have and lower your EC

you cant go buy there directions... there all wrong on 90% of the bottles for most brands... its ridiculous

Dude, thanks again for taking the time to help. The only nutrients I have available (until I can order some) is Formulex, Ionic Grow and Bloom. I can possibly source epsom salts, but that's it.

I'll drop EC to 1.2 and stick with what I have for now. Next week I'll also get an RO machine and then go with that water and a higher EC (possibly 1.4)

I'll also order some new nutrients. The Dutch Pro series get a good review.

Most people I know on well water would kill to have your numbers, lol

N and K are high but in proportion with each other. Cannabis doesn't need a lot of P, especially in veg.

Epsom salt, aka magnesium sulfate heptahydrate, is going to help boost S and Mg, but it won't affect much else.

I've just been to the grow room, used my infra-red glasses to dilute the solution. I've gone with 1.0 EC for now at 5.8pH. I'll see how it goes over the next week.

top page bloom
second page veg

using the nutes you linked me to

actually very nice ratios ..N might be a little low in veg but not much a calmag product wont remedy

but we still haven't sorted out your micro nutes and magnesium/calcium rates (later)

all you need is the hydrogrow and the p-k

for grow stage
hydrogrow 3ml per liter
for 150 liters add 455 ml hydrogrow only

for flower
hydrogrow 2.5 ml
p-k 0.5ml per liter

for 150 liter 380 ml hydro grow and 75 ml p-k

you don't need the hydrobloom product
