Leaves going crispy from bottom up

Can't seem to figure out what the problem is. I thought at first it was over watering but I've changed it all up and started a new batch and I have the same issues. My leaves are curling up and tucking under, starting at the bottom and then going Dry and crispy. Growth is also very slow!

I've checked Ph, been careful with watering, watched nutrients like a hawk, and use only water that's been Ph'd and sitting for at least 24 hours.

Any ideas? Not all plants are effected. But at least half in the last two grows have been. Wtf!

Added some pics.

As I mentioned I started a new batch and changed it up. I guess I should have mentioned that I've been watching my watering very carefully. My bad. The soil is wet in the pic because I transplanted that plant yesterday. Perhaps it's still too wet? I've never had this problem before though and am watering a lot less now

What’s your water like? I.e Mineral content/ppm?

Also what’s your medium/feeding dosage?

I’m suspecting high calcium blocking other elements. It’s a nightmare in high doses.

Phenotypes/genetics vary on how the plant will tolerate its conditions.

I use a cheap soil from Canadian tire. But I've been using the same soil for years. I feed with general hydroponics trio. But these plants started doing this before I gave them their first feeding.

With seedlings in a decent sides pot like that you shouldn't be feeding them for another 2-4 weeks of they're in decent soil. Even in poor soil you should have another couple of weeks. That's not likely the cause of this though. Unless you're feeding them at a high concentration. Small young plants, especially from seed, only need maybe a 25% dose.

What ph are you watering at?

try planting into solo cups or other super small pot. that will make it easier not to over water. dont transplant untill root bound

The only problem with that is that becoming root bound and allowing the taproot to bottom out are two very stressful things for young plants. I start my seeds in anywhere from 1-5 gallon pots.

Not over watering is easy. You thoroughly water once. While they're small mist the top of the soil every so often to keep the top from trying out until they have 4 or 5 nodes. At that point they should have deep enough roots that you can stop misting the top layer of soil and start going by pot weight. It's also important to use a good soil with a loose texture that will encourage aeration /drainage and root development. Depending on the strain, temp/humidity, and size of pots you should be looking at not watering for at least a couple of weeks. That is if you're using good sized pots. Otherwise probably as soon as 1 week.

may or may not be true. ill take your word for it. i have never experienced any stress from that. if thats true though if its from seed regardless of pot size the ( unless your in a 1000 gal smart pot maby even then) your tap root is going to hit the bottom of the container. even planting into a 5 gal bucket a seedlings tap root is going to hit bottom within weeks. better it suffers this "stress" sooner than later right? then what about clones. they have no tap root?

I've read that for cannabis plants the tap root bottoming out at three inches or less increases the number of males. That was in the grow bible and reprinted with permission from a research group that I believe was in the Netherlands. Some other species of plants will even die if a seedling becomes root bound or the tap root bottoms out.

My big thing has always been to make sure that the plant is in a deep enough container that the plant is very well developed before becoming root bound. The main thing is that the plant be able to reach a vegetatively mature stage without being hindered.

Why are you transplanting a sprout in the first place? looks like transplant shock and overwatering

Nitrogen, its a fine indicator of when to start your feeding.
if you had proper soil to begin with that is.

Edit:i use generic soil, does the job 4-6 weeks.

The plants shocked and about to flatline. Give it a drop of superthrive and some ph'd water and start germinating another seed.

Hmmm going to have to do some research. I run a hydro store and give advice a hundred times a day i cant pass on knoledge that i havent verified. Honestly not saying its wrong but it just dosnt sound right. Thought a seeds genetics were pre determined before they even pop. Thats what makes fem seeds possable. Fem dna+fam dna= fem dna
Poped 100s of fem seeds all into solo cups for first pot. Never a male or even a hermie

you can easily make feminised seeds from a plant with silver, herm a single branch, collect pollen, remove branch, pollenate a single bud or two, 20 free fem seeds.

Kewl, his leaves are probably suffering still.

Exactly the seeds sex is pre determined and a shallow tap wont change that

if he only has that 1 plant tho and wants to preserve it, thats his best action. you cant clone a crap branch, but u sure as heck can squeeze a seed out. Idk, I got my afterwork bake goin on so im gettin foggy.

either way, its early enough with enough problems that I would scrap it and restart. just my opinion tho.
