Beginning of Leaf Issues- Day 31

[Jackson]

Hello All/

Today I noticed a slight discoloration of a few fan leaves. See attached pics.

She is an auto sour Crack planted in GBD soil and roots organic soil.

Under solar flare 220 LED's watered with distilled water. Ph runoff is 6.0. Fed 1 week ago with 1/8th teaspoon of GO cal/mag.

This is my 4th grow and continue to have issues.

Can anyone help?

That's pretty classic calcium def, Jackson. With GO cal/mag, a light feeding is 1 tsp per gallon, heavy is 2 tsp per gallon and I've used even heavier rates when needed.
Using distilled water, plus the LED's, you're gonna want to up your rates. Personally, I'd jump right to the heavy feed dose of 2 tsp per gallon, and adjust up or down as needed.
What pH is your water/nutes going in? Is there a reason why you're using distilled water?

you need a ph soil probe.. this is a good one. ph-ing run off is never accurate.

Thanks guys for assisting me!

I have been told I don't have to ph with distilled water. Last grow I was told I overdosed it with cal/mag although I didn't think so and it looked burnt.

All of my grows get out of hand when they begin to full flower.

I'm very confused and should just stick with fishing.

I'm concerned that I will burn it with a full dose and then have to start all over again. Just kidding about the fishing part although I love fishing

Lol! I recommend fishing and growing
Distilled water has all the mineral content removed, usually the most predominant ones are calcium and magnesium. And leds are infamous for cal/mag issues. We all have our comfort zone, but I have yet to OD a plant with cal/mag (don't get me wrong, it can happen).
At the very least, feed 1 tsp per gallon, and move up from there, though I still recommend the heavy feeding at least for the first dose.
Checking pH becomes even more critical with distilled. Calcium and magnesium are great buffers (something that helps maintain a reasonable pH range). Some folks don't check, and some nute lines say you don't need to... I always do, it's just habit, and my well water can fluctuate wildly depending on our ground water levels.
GO Ca/Mg + contains no nitrogen, either, so no worries on that end.
GA6 is on the money with his meter choice

Thanks bro. Will feed her cal/mag this evening I guess at 1 1/2 teaspoon. Get in the middle of where you say. Just concerned about feeding too much. If you search my older threads on lowryder you will see pics of burnt leaves which happened almost overnight. Looked like I used a torch on her.

Ok. I gave her 1 teaspoon of Roots Organics Elemental which is ca, mag and sulfur.

Let's see if she recovers.

Question for you Redneck? I fed her Roots elemental this morning at 1 teaspoon powder. Should I have given her GO cal/mag instead? Also, if it looks worse then what?

Hello All

Today is 34 days old and I don't see any additional issues with leaves. I gave her a teaspoon of Roots Organic Elemental Monday morning and it appears to have spreading defecitcies.

Should I continue feeding/increasing with every watering?
