Spots on leaves, red stem, burnt leaf edges??

So I'm not sure if this is a cal/Mag deficiency or a nitrogen deficiency or something else?

Whats your ppm in the rez?

My NPK brought my ppm to 1100 after I added cal/Mag, diamond nectar, and honey chome it went up to 1200

You're cooking them alive.

yeah 1200 is like 3 weeks worth of nutrients , next time just dilute them with more water.

Why are you adding Diamond Nectar and Honey Chome to small vegging plants? Both of those products are a waste of money to begin with as you're just adding phosphoric acid, potassium hydroxide, and sugars. If you do bother using them they're to be used in flower.

Just run your base nutrients and call it a day.

Good luck

That's a tricky question. Diamond Nectar is phosphoric acid and potassium hydroxide.

Phosphoric acid is used as a pH down and organic substitutes for that purpose would be citric or acetic acid. In the case of Diamond Nectar it's used to supply phosphorus. Down To Earth has an organic 0-12-0 liquid bone meal.

Potassium hydroxide is commonly used in soapmaking, battery production, other industrial purposes, food production, and some nutrient additives. Agsil 16H potassium silicate is approved for organic use.

Those are just water soluble. If you are mixing into soil then there are many other alternatives. You should probably start a thread over in the Organics section. There are people much more knowledgeable than myself regarding organics in that section and we shouldn't hijack this thread.

so 770 total PPM from week 0-3
a total of 990 PPM from week 4-7
i would make a water solution that is around 400-500 PPM make sure to check PPM AFTER you PH the water

OK cool thanks dude!

Let your girl tell you how hungry she is. Set it at 500. If it goes down, she's feeding. Raise it 100. If it goes up, she's not feeding. Lower it. Eventually it will level out that's your sweet spot, keep it there, with my grows this is normally 1000 - 1500. You should be nowhere near 1000 with a plant that old!
