HYDRO I'm tired of having problems with hydroponics, what am I doing wrong??

Hi MithrilSCYTHE
not a Hydro guy here, was just wondering do you always drip in a nutrient mix solution or do you mix it up with plain Ph'ed water?
looks like Nute burn to me.
 
You can do this! What nutrients and additives are you using? Something in your calculations is wrong and we’re going to figure out what it is! Whatever tools you are using are only as good as their accuracy, get some strips to compare and calibrate monthly. I use all blue lab meters and constantly comepare them to ensure they are correct. With my water things can change drastically. If you are taking samples of your res to test make sure the container is free of anything that may skew the reading. I don’t mean to sound obvious, but somewhere, something is wrong and at the point where you think everything is perfect you may need to test some of your known factors to get to the bottom of it
 
Yes sir! :D
My pH tester is good quality, not as much as bluelab, but it's reliable, I calibrate it every 1-2 weeks, the result are comparable with the strips and the other cheap ass pen I have for redundancy.
I'm currently using the GHE Flora trio (hardwater specifically for the micro, even though I don't use hard water. I have read that the only difference is that one I have doesn't have any calcium and magnesium, thing that I supplement with...)
Ionic Mag Cal Pro, growth technology.
It's literally a copy of the calimagic.
Then I use the Atami B'cuzz root Stimulator, a vitamin supplement.
I periodically add Liquid Oxygen, growth technology, nothing fancy, just hydrogen peroxide 20%, I add 1-2ml/l every time I can.
My pH up and down are also from growth technology.
I also have liquid silicon, but I never use it since almost every one I encounter online tell me I have probably a pH problem, and silicon makes pH a mess to manage.
Epsom salts too and mineral magic, never use them, I don't want to put things more than necessary.

As for the ambient, I have a tent, 45cm x90 cm, 160cm height.
I have reflecting walls in mylar, and my lights are a Platinum Led P300, a 90W blurple led in veg, that doubles the doubles the W when in flower, then I use some homemade quantum "tablet" (since since is too small to be considered a board) 4000k 17,5W to ampliate the spectrum, both kept relatively high (my plants grow squat already, no signs of stretching.

Hope that this explains my situation well
 
I never went below 5,8 with my pH.
Is there so much difference between 5,5 and 5,8 to justify my plants deficiencies?
I soak them well, but this is my case
 
Wow! This looks great!

Can I ask you what a hydro tub is? Is like a place where you put your plugs to dip but not fully soak?
Do you always do like this? I'm actually using I technique I find for rockwool cubes, where you let dry the thing before dipping it again, so the roots grows to the edges and when you move them they should expand immediately in the new system.
Does dipping it constantly makes things better than this? Thanks!
 
Yes, you are boarding manganese deficiency above 5.8. Mn absorbs at a lower PH than most other elements.
 
Wow, you'd be the first one to tell me this. I burned once a plant, I'm never making the same mistake again, my ppms are way low for a nute burn, 400-500ppm.
Also not having signs on the tips of the leaves, but mostly on older leaves, in between veins
 
I just dipped them again, this time in 5,5.
After dipping them i tested again the water where i put them, it was 5,7! So that means that by averaging, the ph inside the cube was at least 5,9-6.0 but probably much higher! Damn it! I will dip them again in an hour to be sure the pH stay low at least at the immediate beginning
 
The only other thing I would suggest is magnesium it needs 6.2ph and up to absorb in Hydro.
Good luck.
 
When u dip the cube it becomes over watered is my guess.Not much air and stagnate.I have never done what your doing so Im just guessing but i think Im right.Get it in a netpot add som bubbles and 1/4 strength nutes.
my last grow went into pots 3 days after the seeds popped.

I use KINGLED - 1500w (There are better lights available) but the cost per return for these lights has made them a keeper for me.
 
Well I thought I had bought the state of the art and I'm running a few more actual watts than you. But you sure are kicking my a$$ all the way the way around. For what I have in my 2 could have bought 5 of those. Wish I'd seen this grow of yours before I pulled the trigger on my LED's! Again damn nice grow!
