Growing in organic super soil and only watering with R.O. water nothing else

This is started a couple days can’t figure out what the problem is. Feed back would be appreciated thank you grow community

The tips look fine, it can be a sign that your VPD is running high - if you can bring the RH up or your air speed down it can help. This time of year for me is “drier than a popcorn fart”. But the burnt tips or the high VPD ultimately won’t hurt the plant, it’s just not optimal.

What concerns me a little more is some of the light coloration between the veins of a few of the leaves. When I see that I’ll water the next time or 2 with cal mag.

In your case though, using the RO water, Id also want to check the pH of the soil. The mineral content of water has a lot to do with its ability to hold a stable pH.

@Noddykitty knows a ton on the subject and he can probably also tell you if I’m way off in my suggestion.

Is there any brand or product or way I can add cal mag organically?? I want to grow the 100 organic and natural method preferably much appreciated !

The cal-mag I use is OMRI listed. I’m pretty sure it’s horse pee. :rofl: I hear you on not wanting to use the bottles though. I also grow in a living soil -ish system with organic amendments, no bottles (other than the cal mag). Oyster shells, and crab meal are some good sources of calcium but it’s not a quick fix, it has to be broken down.

Well, I was mistaken. I’ve been using Botanicare brand but I don’t see the OMRI label. Looks like Fox Farm has one.

:v::laughing: Horse Pee? LMAO!! Always used Lemon Juice. Two drops a gallon, if I’m using Distilled Water. Two drops brings 7.2 water down to 6.4 … What vitamins and minerals are in lemon juice??

In addition to vitamin C, lemons also contain other important nutrients: fructose, fibre, potassium, calcium, magnesium and copper, as well as vitamins B1, B2, B6, folate and pantothenic acid.20211108_000734

I agree. I will use orange peals and break them up in roughly 1 sq in. and start with three pieces for 5 gallon and two pieces for a 3 gallon, especially helpful for alkaline medium. Over night it dropped one of my girls from 8.8 PH to 6.5. I am a new year though so input welcomed. Nice to meet you guys.

What nutrients are you using? What feeding schedule? This is obviously tip burn from too much nitrogen.

No nutrients just Oregon organic living soil and feed when the soil become dry but not over water
