Seedlings stunted growth

I planted 3 seeds from seedsman. Took 10 days to germinate due to low humidity and cold temps, (I’ve fixed that issue). So currently at 11 days veg since germination under MH fce3000 at 15% for germ and 25% for veg at 30 inch height. I keep the RH at 75-80 and temps at 70f-79f with circulating fan and vent open to balance pressure. The white widow germinated second to last but the other 2 have far surpassed the white widow. The white widows cotyledon leaves shriveled up around day 9, I’ve been watering with 6.78 ph water from tap that has sat. I’m also using recycled fox farm soil i used from a previous organic grow. I’ve been mixing and watering a 4:1 nute-water ratio in a cup with 1ml of ff big bloom, 1ml of grow big, 1ml of cal-mag, mosquito bit tea (fungus gnat kind), and 1/16 teaspoon of recharge amongst all 3 seedlings and using a 1ml dropper until the top layer is moist. Only watering when the soil is dry about .75 inch deep. Using this method until I transfer to pots with amended with dry nutes. The other two seedlings are doing great with this method. The roots of the white widow don’t seem to be deep as some movement will displace it.

What is causing this stunted growth?

You outlined your problem yourself.

ALL seeds are going to pretty much grow different, especially different strains. This is the reason we take cuttings off desirable seeds and take cuts aka clones off them and grow based on desirable traits.

Good news is the plants look fine, better news is you've already taken pictures and notes of how each plant is growing. Keep doing that, the plant you like the most by growth traits & smoke number it and keep it by cloning it and growing it again.

You're already doing a good job "pheno hunting" just remember to number the cups and keep track of strain etc.

Cheers

What is the problem exactly? This wasn’t helpful at all lol. Is it the recycled soil? Is the the nute method? Be specfic please.

It’s anything with nutrients including used medium. They need nothing for the first few weeks.

so u don’t think it’s stunted growth? I’ve grown these seeds before, (I got a 3pack) last time I didn’t get this issue. But the only difference was I didn’t use recycled soil and I didn’t have the humidity and temp issue cause it was started during spring. This go around I use recycled Soil amended with 1/2 cup of dr earth 444, 1/2 cup of coast of Maine 542, 1/2ewc, 1/2 cup humic acid, and mixed in water mixed with recharge and temps were at 61-72f and rh at 38-48

So I shouldn’t feed the white widow any more, just plain water for it? I encountered slow growth from all 3 until I started method from above

If using any nutrients just use a drop or two of your grow nute. Don’t keep medium wet. Damp is good enough. What light are they under and what’s the temperature of the room?

Should I dilute it any if I drop a drop of nutes in it? Or leave it full strength? And I’m using a 300w mars hydro fce3000 at 25% brightness and my temps are steady between 70-80 degrees. Usually reaching 71 at night when lights are off and back up to 74-79 during the day with lights on

Update: 2 days later after giving just water. Seedling started to fall over. I don’t believe it will make it
