Help! Brown Spots on oldest leaves!

[Weouthere]

Hey guys! My little plant is now 12 days old. Growing in a 2x2x4 box I built and painted white.
Light: 32w Feit electric 3 spectrum LED (upgrading to ms ts1000 very soon)
FFOF/perlite mix about 60/40, 1gal pot
Box isn’t totally sealed up, that’s gonna be done on payday.
I’ve seen little bugs in there and I’ve neemed the box once, and the plant just today.
Also thinking calcium def?
I went to check on it this morning and noticed these little brown spots. Sorry they’re so hard to see, I’ll try to get some better pics after work.
Don’t know what they are!! Any help is appreciated
Edit: water with distilled or tap water, kelp extract every 3 weeks (only once so far)

Perhaps its a cal mag def, look at the photo

Btw, put aluminum paper on the walls. it return the light to the sides of the planet, its important.

The plant looks good to me.
Those spots sometimes develop on older growth in the early stages and it's best to wait to see if it continues to spread.
It's to soon to have a deficiency if the soil quality is good.
I would keep doing what your doing and monitor the plant.​

White walls are good. White panda film is good.
Aluminum foil can create hot spots.
Not sure if aluminum paper is a good choice or not vs the white walls.

No the cheap kitchen aluminum
There is a material for this in the hydro shop, I don't know the exact name, I think its reflect more than the white wall.
Like the inside of the growing tent.

MYLAR! I’ve been thinking about making that addition, but the paint I used reflects about 85% of light so it’s not bad!
Figured it’s a calmag issue, so I gave a small dose this morning. We’ll see what happens.
Also removed all bugs and moved the box from the garage to inside

Using FFOF and watering with distilled water, and kelp extract when I transplanted it up. Didn’t think ffof had calmag issues but I think it’s more prevalent than I was led to believe​

You will hear bad things about FFOF because they had problems in the past but I think those issues have been resolved.

A good practice would be to look at calcium and magnesium separately when reading the plant.
The plant shows no signs of a magnesium deficiency.
Calcium deficiency can cause dead spots but the dead spots you have are not likely to be from a calcium deficiency. More like growing pains of a young plant.

It's better to read the plant to see if it is a real deficiency that progresses vs feeding the plant something it doesn't need.

FFOF doesn’t have calmag issues persay. It’s the “ distilled “ water choice.
Why use stripped water ? .... that’s why you are getting spots. It needs the minerals boiled away from distillation.

Use tap and keep the distilled for ironing your pants and steam iron.

Ok.but if your tap water is hard, then what. I'm in my second week and have used distilled, sparingly of course.

Then use distilled with added calmag, if your water has too much calcium or iron in it.
Or just get a cheap inline cartridge filter. You just have to remove the excess calcium, iron, chlorine to lower levels.
Read up on Cation Exchange to see why straight distilled is not preferred for use.

Ok. I've got filters water out of the refrigerator, and a Britta? I think iron and calcium is definitely an issue in my area.

Older post ,but relevant to my pressing issue. Any help will be appreciated.
I just looked in on the plants and noticed this on the far side of the one having the issue. Two weeks Into flowering, and of course this is the biggest plant and it ended up in a 2-gallon pot because I ran out of five gallon pots! I have used distilled, and spring, and filtered water. Local is too hard.
The issue is that I noticed the main fan leaves are starting to Yellow starting at the bottom and working their way toward the top. Just in the last week or so. They're up to the fourth set of fan leaves, and just starting to show on the 5th set. Then.....I noticed brown spots and more discoloring. Also, looking at the other plant that is the same strain, even though they don't look identical structure wise, the plant that has an issue is more of a lighter green color than the other plant. This is all happened fairly quickly.

Without knowing about the grow it looks hungry from the look of the mid and lower fan leaves.
Might need some nitrogen and possibly some magnesium. Might need a balanced feed IDK.

For new growers a common mistake is to switch from veg nutes to flowering nutes to quickly applying to much phosphorus when they begin to flower a time when nitrogen is still needed, another common problem is keeping the soil to wet.

It's water only soil. So I haven't needed to feed. And I let it dry out before each watering. I'm paranoid about over watering. This plant ended up being the biggest, and of course wound up in a 2gal pot, rest got 5gal. So I'm thinking you might be right. I'm thinking I need to transplant up to a 5gal even though I'm 2wks into flowering? I'm out of the water only soil but have just enough of another soil (pic included) is this ok to use? I have some Recharge on the way to help kick start the microbes and hopefully that will help her get back on the road to normal. Any thoughts would be appreciated. Also attaching a couple pics of a couple small brown spots nearer the top of the plant that are recent. Thanks for the help!

Looks like mag or potassium

Just bc it says it has food it's only a 10 5 5. You need to add what the soil doesn't have readily available for the plant. You have the main 3 npk, but also need trace nutes as well nickel boron copper zinc ect. After a couple weeks the plan has more than likely used up what it can take from the soil.

I don't think it is a good idea to transplant this far into flower. Roots spread during veg and don't spread very much after a few weeks in flower. I'd feed it and ride it out.

Just an update guys I flipped to flower the other day. Already seeing pistils
I also wanted to point out that small spot (original subject of this post) was definitely “growing pains”. I’ve been using tap water left overnight and I’ve never had another problem in my ffof.
This is her yesterday!
To the new growers, really make sure you’re diagnosing properly and knowing what you’re putting into your plant.. since early September I’ve done lots of research on what’s actually in my water and how much.
I have really good water here with minimal inputs from the water company
