Name this seedling "sickness" - pics - Bagged soil and well water -

Hey guys, I started up some regular seeds almost 2 weeks ago to be ready to plant them outside right in the ground for this years outdoor. I started all of these plants at the same time, yet notice the huge size differences, also how decent some look, and how sick others look.

I used a fresh bag of Promix Organic SOIL - I have waterred twice with straight room temperature well water, no additives of ph adjustment of any kind. They are in fabric pots in my 2x4 tent under almost 200 watts of quality samsung LED at about 18" above canopy height

How is it possible that these plants are showing such sickness already?? I had trouble last year with spotting yellowing leaves but I was using alot of nutes with my rain water (I have rain barrells but they arent filled yet), I have only waterred with well water as mentionned, we have our well tested and it does test high for iron but safe for human consumption, could it possibly be to high for plants?? To do this much damage? Wife waterrs all the house plants with it and Ive never seen a hint of anything wrong with any of them

I am on the fence on what to do with these plants, almost want to start over, but I need to know what I could possibly be messing up with a setup so simple first so its just not another round of this

Ok, well water, no pH adjustments. Thats probably pretty alkaline.

Never used the promix organic soil. The promix that I have used in the past had no NPK values to speak of, soiless mix, peat based. So you have to feed it. Look at your soil bag and see if it has any NPK numbers. If not you need some nutrients. Sure looks hungry.

pH should be at 6.5.

ph of my well is 6.7 - 6.9

I already tossed the bag for the promix, but it was the organic soil version, not the promix hp soilless type that Ive used before

That isn't bad for well water.

Can you find a listing online for the mix you used? I would like to see if it has any nutrient values. Chances are the plants are just starving and need some nutrients.

Also, too much iron can cause problems, you said the well water is high in iron. Plants need iron but in very small amounts. If my memory is correct, more than 5 PPM of iron can cause issues. More than 10 PPM can get pretty toxic. Iron is also capable of locking out manganese. Iron and manganese should available to the plant in the equal amounts.

A water filter may be in order. Do you have an analysis of the water?

If the problems with feed can be fixed the plants can recover with healthy new growth. So it's probably too early to give up on them plus fixing them can help you pinpoint the issue for future grows.

I do not have our water analysis on hand but I do believe iron was above 10ppm. The water does pass through a sediment filter, and then a UV filter, but I dont believe that stops iron. I plan on waterring with rain water, but I have just setup this up for the season this weekend and they have not collected anything.

This is the soil I purchased, it does say it feeds the plants, so I would imagine there is some NPK in the soil, but am unsure the ammount. I figured all would be well and great for me to simply start these plants in these pots for a month before I transferred outside

My well water comes out of my tap at 7.5 to 8 ph level. I grow organics soil as much as possible. I have measured my runoff ph and it always hits at 6 to 6.5 ph. I have never used promix. I have had only used roots organics soils, and fox farm soils both pretty much designed for cannabis. I believe the more organic your soil is that your root system will naturally buffer the ph. That's just from what I've seen wi my own.

Ya I figured I was going with a fool proof simple setup this year, soil starter bags then right in the ground outside.

Checking that promix organic on the promix website it doesn't list any NPK values or nutrients in the ingredients.

You will need to feed the plants. pH the feed to 6.5 for best results. I would start out with something around 750 PPM and go from there.

With proper feeding your plants will produce happy new growth and you will be off and running.

Make sure to water with 15 - 20% runoff to prevent salt buildups.

Happy Growing!

It says right on the package it can feed for 3 months, thats kind of mind blowing theres nothing in it if true

Hmm, some happy, some not. Not ones, look Ca/Mg hungry too....Wonder how well that "soil" was mixed?

Im not sure at all, came out of a single bag, I broke it all up by hand first
