Mephisto Genetics Slow growth, is this typical of autos?

Thanks for the info. I didn't realize autos were known to be fussy & picky with things like soil temp. All regular photo period seedlings I've grown in previous years have never flinched, they certainly grew faster as they days warmed but even the cool nights & mornings and shorter days of late March/early April wasn't an issue for em'.

I also didn't realize autos were fussy about having to start in a light/fluffy "starter" mix. My soil isn't too heavy but it isn't anything like some of those super fluffy mixes I've seen. And again, I've started ALL of my seed grown plants in this same soil for several years now, photo period plants, and none have had an issue with it.

These two variables could be playing a part in what's going on, I just didn't think or know that autos could be so picky & fussy about such things. I mean it's been a sunny & warm spring for a while now and anything that's been dropped in this soil over the years has grown up just fine (tho it isn't the most light/fluffy soil, it isn't super dense either, I added more coco & perlite this spring).

It was a little "cold" (relatively) for the first 5 to 7 days or so after they germinated which was on/around May 16th. Low temps in the morning were around 50 and daytime high temps were around 75 for the first week or so. But since then it has warmed up to around 80 to 90 during the day time. The soils around here have been plenty warm for all sorts of things to germinate for a couple months now, but yea it was a bit "cool" (for this area) during their first week.

The day time temps are about to be up around 103 to 106 here for the first part of next week, I think the soil should be plenty warm by then lol. I've never had any plants struggle much with the heat & dryness in my area either, I'm curious to see how these autos do.

I'd love it if they took 6 to 8 weeks from sprout before flowering (to an extent, I am moving later this summer and that's the whole reason I'm growing autos because I can't finish photos), in that amount of time I can see them taking hold and taking off and growing into a decent size plant...That's the main thing I'm concerned about is them flipping into flowering early while still so small.







Each plant is in a 30 gallon fabric pot, but they are filled up only 2/3 to 3/4 . I know that's a bit large for an auto but that's what I have on hand since that's what I've grown my photo period plants in in the past several years (as well as in the ground).

Two of them are in 1 gallon plastic pots which I was planning on transplanting into the ground. Initially I was thinking I would be doing so around week 3, like I usually do with photos, but it'll be a bit longer before I do that for sure.

Today I placed a seed directly in the ground (Skywalker).

The nighttime temperatures of 50 degrees is an issue. I've had 40's at night and it really slows down the growth.

Not much of an issue with the photos I have grown, but it slows down the autos I have grown outside. My daytime temperatures are usually no hotter than low 80's though.

Last year I had to put my auto plants in a pole barn at night for about a month and a half due to lower temperatures once the sun went down, or cover them at night by building a frame to hang a tarp.
 
They move quick when they're happy !


I've seen how fast cannabis in general can grow. A couple of my photo plants last year were packing on nearly 1ft of growth per week on each branch, they ended up super chunky around 7ft tall (did a lot of bending/topping to keep em' short).

I was just looking at pics of my seedlings (photo period) from last year that were taken around 2 weeks after they germinated and they are all much taller/larger and more developed than these autos I have going right now. And the photo period seeds I had going last year were started under shorter and cooler days. Damn near all seeds I've grown over the past several years have shot up to the sun just fine, packing on noticeable growth each day.

I've never ran into this before with any seed or clone started in the same soil and in the same climate. I didn't realize autos could be so finicky & fussy.

This is day 7 straight into promix ultimate under shitty led shop light. They stretched a lil at first till i dropped the light .View attachment 1324224View attachment 1324225

That's about how far along most of mine are right now around day 12/13-ish, as far as leaf & "node" development.

Though mine are super short & squat, not nearly as tall of a stalk (they get a lot of direct sunlight through the day). And the leaves on mine seem a bit smaller (could be genetics tho)

One of my mango smile is farther along than that tho, looking decent actually.


I'll try to get some pics up tomorrow so ya'll can actually see what I have going on lol.

Thanks to everyone for your input so far.

I know everyone has their own methods but I had the most success by transplanting from solo cups at 9-12 days to final pot and then putting them outside around 21-25 days. I also never left them outside at night if temps went below 55f.
 
I think we have already nailed your issue, but even with everything else perfect in the grow you will see different behavior than other folks since your using 30 gallon pots. I’m just throwing this in for future reference, but in containers 10 gal or bigger- at about two weeks the above ground growth will slow down as they grow an awesome extensive root system. After a while the above ground growth will resume at an incredible rate. Some folks see this and think they are stunting, but they aren’t, so don’t panic if you see it. I’m a no till soil guy growing in 10 gal sips. Always happy to help and encourage another grow bro doing the big pot soil gig!
cheers
