Please Help with calmag issue?

[LoveGrowingIt]

77f and I just lowered it to 60% from 62% vpd goes from 1.15-1.22. I could probably lower my humidity a tad. I have an ac infinity tent with a heater and humidifier. Two circulating fans and a 4” exhaust. I’m thinking it’s in lockout too I just don’t know how. I’m feeling like the soil may have some dry spots in it. Idk if that can cause lockout but I feel like I read that somewhere.
I ran 2 ga. Of water through it this morning hopefully it’s looking better or at least not worse by next watering.

The temperature is good. Humidity in the 50s or high 40s is typically better during flowering. Your VPD seems a bit off, so I'm wondering if it includes leaf temperature. I tend to forget to include it. So, I doubt this is the problem, though. That said, the plant might benefit from a little less light and lower humidity.

@Newbgrower1

When did you start calmag? During veg?

You'e using Happy Frog. Its well buffered and is probably between 6.0-7.0 soil pH range. )Hopefully closer to 6.5 which is the real sweet spot for soil grows). I'm curious on when you started calmag, how much are you using when you use it and how often you've applied it. I'm inclined to believe you've locked out your soil and calcium isn't available to the plant's use. However since so many leaf issues represent multiple potential problems, we'll still need to dig deeper to get to the "roots" of your problem. Yes, its something in the root zone. I'm going to guess excess of something locking things out.

I missed this comment sry. I’ve only used calmag once. It was 3 days after I noticed brown spots on the mid leaves. 2 days after that the leaves were yellow and the brown spots were getting bigger and other leaves started getting spots as well. I was adding epsome 1 tsp in a gallon of water every other watering. Do I need to flush every once in a while with epsome salts? Or maybe I gave it too much and that locked out the calcium? I really don’t know. I also read recently that dry spots in the soil can cause lockout as well. I was watering 1 ga. Every week but even tho the plant didn’t look dry I feel like it was getting too dry. So I switched to a half ga. Every 3-4 days about 4 wks ago.

Indoors in smaller pots, organics can be a struggle. People do it. I used to myself but switched to GH Flora series because of ease of use and consistent results. Organics is a timing game. Microbially speaking, there's a lot more involved in turning organics into plant food and therefore it takes some experience to be consistent with theses timings.

Outdoors in raised bed gardens, much larger containers, or in the ground, organics works wonderfully. Indoors, you would not be the first to struggle. How much calcium is in your tap water? Any idea? That's a leading contributor for some people with naturally hard water sources.

Edit: I also noticed you added gypsum to your soil mix.

I don’t think I added gypsum but my memory is shot lol. Can you quote when I wrote that so I can go back and check what I put in. I’m starting to get that the schedule is very important when it comes to organic and I’m not very consistent with my feedings. Like you said my outdoor in my garden do great with it but my indoors always seem to have issues. I’m using 5ga. Airpots for the first time also so the dry back is a little different than I’m used to.

My bad, I went back and checked. Another poster said they added gypsum to their soil. I lumped that part in with you. If you are 100% set on organics, there are growers here who have the experience to guide you through their process. I use salts. I like the consistent results. My results were all over the place when I was running organics.

@GNick55 any suggestion on how to help with the light stress? Besides moving my exhaust to the outside of the tent so I can raise my light. Idk what to do. I feel like I’m already very low on the settings at 3/10. I’m on a 20/4 schedule now I can go to 18/6. I definitely agree I’m seeing light stress on the fritter now but I’m running out of height and she keeps stretching.

Lol all good. I know I bought a box last year but haven’t been able to find it. So once you said that I’m like did I use it for this grow? Lol ive Ran organic and synthetic and honestly I prefer synthetic. I just travel a lot for work and thought feeding once a month would be better for my situation. So I only needed someone to water, not add nutes also. I did just get some 10ga. Fabric pots. Maybe I’ll try that with my next organic grow. And I checked my water and it doesn’t say anything about calcium in the report. Unless I’m missing something. But then again I don’t really know what I’m looking at lol

That only looks like one page of the report. I don't see any mention of pH or hardness, criteria that is included on my water quality report from my municipality. At least in my area, it would be strange to find a ground water supply that doesn't have at least some calcium in it.

I'm no longer convinced your issue is calcium lockout though. We could be over-thinking this especially since I thought the gypsum in the soil was a move you made ... only to look again and find out it was another poster.

I felt like it was calcium deficiency not necessarily lockout. But i really had no clue so I went with the majority. lol I only ran 2 ga. Of water through it so no harm no foul. But idk if I should add calmag or just start a synthetic feeding next watering?

I would go with a calmag feeding as directed on the bottle.

I would also be looking to provide a boost in K by adding a potassium sulfate bud finisher in the next week or so and then run that in addition to your feed routine until the final week of your grow.

Ok thanks I’ll be watering tomorrow so I’ll do the calmag. I was using Gaia green that takes two weeks to supply nutes. Do you think I should just switch to synthetic. Or I have some roots organic bloom I can make a tea. Thanks for all the help.

So I went with 1.25 ml of calmag and 1 Tbsn of roots organic tarp tea in 1 ga. Of water. The calmag called for 1-2 ml and the terp tea called for 1 tsp-1 tbsn the terp tea was a lil old so I went with the max. I watered the bb cheese with half of it and the apple fritter with the other half. I started getting brown serrated edges. I’ll probably do the same thing on my next watering if everything is starting to look better.
