Why is there 5 "cal-mag" threads for every 1 nitrogen thread?

Yup starting to notice that too much light and/or ferts and you can cause a deficiency/lock out in something for sure. I actually have started a regimin of lowered lights in the beginning and then turning them up in stages and bringing it back down in a similar way.

It's all a balancing act and if one of the 3 things is F'd up things can go sideways.

Really starting to look at making up my own soil as well. Tried Coco....not happy with it.

good point. I find that too much light will slow plant growth. i'm an old soil grower and don't know anything about hydro. never considered trying it. too much work and too many things can go wrong. more concerned about growing high quality medicine than high quantity. not a commercial grower and don't make money from my grow. I grow more than I need and give my surplus to cancer victims.would rather have 1 ounce of 1 hit bud that effectively treats pain, nausea,depression and insomnia that 1 pound of mexican dirt weed :):):)

"I know EXACTLY how much calcium and magnesium my plants use over a week "

Oh please give a rough estimate on your Cal/Mag usages in like 4 stages?

Growth, preflower, flower, and late flower that will work! :D

And it will help just give a guideline as to what's possible.

I'd supply you with that info but those tests cost me a few hundred bucks.

There are several analysis labs around the country that would gladly accept your samples and your money. Please let us know how it goes.

so, what? just a smoke screen?

you stated you tested it and you know exactly how much everyone's plants use, but you won't share because you had to pay for it?

lmao

I'm not here to hold your hand while footing the bill for your education. You have as much access as I do, start researching and testing.

I see so not even a round about idea thanks anyways. have fun. o/

My plant food contains 2% calcium and .5% magnesium and that is plenty. If your numbers are close and you're feeding with a balanced food then you don't need to worry about calcium and magnesium.

i don't need my hand held. i don't ask grow questions. i've got this, and have been successful for a couple of decades. so, about that cal/mag thing?
 
theres ABSOLUTELY no reason to add calmag if you have a decent fertilizer.

most of time, growers think they have calmag issue but its a mistake.

calcium is always abundant if you use calcium nitrate fertilizer cause the uptake rate is really slow compared to nitrogen, potassium and phosphorus.

Your plant will suffer from other deficiency before calcium deficency.

Maybe need this next? ;)

mine is 5% calcium and 0% magnesium.

as i said, i don't need much calcium, but i DO have to add a small amount to the res. i DO have to add magnesium, as my base nutrients do not contain magnesium.

you should tell us what nutes you use, so we can all be exactly the same and agree with each other! :D

lol , so much shit useless in hydro store, i didnt bought shit for one year right now,except a ph pen. i have 5 gal of nutrients. i use it with straight ro, no ph adjuster, no calmag or anythings and I use the 2 same bottle from clone to finish. 0.08$/gal@full strenght

edit: ahh i forget , i use benneficial bacteria too!

too high in phosphorous, better to add potassium sulphate (0-0-50, so make a gallon, then supplement nutrients like any other booster).

K2SO4, super phosphates can cause the lockouts that raise ph and make it necessary to add cal/mag.

with something like that you would need to dilute the ratio.

It's all about the balance which I am learning about more everyday!

Well based on those numbers and an earlier post, you might want to check on your florabloom bottle for the magnesium that your floramicro is missing.

mix k2so4 with a gallon of water to make concentrate. then, 5-10ml per gallon to add 100ppm of potassium... trying to mix monopotassium sulfate and potassium sulfate isn't as easy as just weighing them out and mixing them up. so trying for a 0-9-18 is a bit more complicated...

Lol; at first glance i thought u told him to use h2so4... k2so4 is much different.

Yeah, you need to know the ppm and the actual % and Math. It's easier than most would have people believe. :)

Researching any chemical you intend to mess with is always a good idea as well.
