pH Nutrient Uptake Chart for Hydro

This chart just blew my mind. I'm on my first Hydro grow and this explains so much.

I kept on having deficiencies and couldn't figure out why. Well, maybe because I kept my pH at 5.8 and always ended up changing out my rez before it had a chance to really change. This was causing my problem.

I could of used all the Cal-Mag I wanted but my babies weren't getting any of it!!!!!!!

All thanks to this chart. If anyone has any other charts, please post them.

Great chart, but the problem is I have a few charts and all say different things... anyway, I don't keep my pH at 5.8 but at 6.1 and the plants seems to enjoy.

From the chart I uploaded, apparently Ca is unavailable at 5.9+ and Mg in turn below 5.8.

Although this one i probably rubbish, because most charts say otherwise.

What's wrong with 5.8PH? That's just about perfect for hydro. Range of 5.4-6.2 works, I keep it between at 5.4-5.8 for veg, 5.8-6.2 for flower. Most of the needed nutrients for veg are easily available below 5.8, except P and Mg, which are needed, but not nearly as much as in flower. Raising PH to low 6.0's in flower make N less available, but P and Mg more available. Every plant is different though. I have one that runs in the high 4.0's low 5.0s no matter what I do, I can adjust and it drops in a couple hours. It's healthy and grows vigorously, so IDK. It's like that both in veg and flower. If I try keeping it above 5.6 for more than a couple days it starts looking like crap, almost like deficiencies. .it's weird.
My other strains love 5.8-6.0.
