I gave them 4 weeks of growth from germination to 12/12. The Skunks have grown quite a bit, but the other pure indicas have stayed small. I'd say the Skunks have more resin. I think they still have a lot to say. It said they would be ready in 8-10 weeks, but there aren't any at 8, and I'd say there aren't any at 9 either. They have a faint smell, but I don't know what it is. I don't recognize the smell of Skunk. These pure indicas are leafy. I like the Skunks better; they have more of a sativa structure.
As you already know indicas take a long veg due to no stretch. I'm not sure if bigger would've been better just check the roots after harvest and see if any look rootbound
That could be salt build up from the mineral nutrients you’re using since you use them every time you water your plants
With mineral/salt based nutrients it’s adviced to use plain water once a week with good run out to prevent salt build up in the grow medium
Have you measured the EC of your watering run out? Is it higher than the nutrient solution’s that you pour in?
So if your run out EC is higher than your feed’s then it’s better to flush the grow medium very well with very mild nutrient solution – with like 5% strength of normal feed - till you get the run out EC to drop

I haven't measured the drainage EC because it doesn't drain, nor had I thought it necessary, fertilizing according to the table. I haven't watered once a week as you say because it's not indicated in the table either. The manufacturer said to add fertilizer daily. It could easily be what you're saying...

Yes, the production is fine, but I'm going to water them with just water and measure the drainage EC, as my friend says.
When you use salt based feed you need to see good run out after watering your plants, so that older salt build up gets washed out a little bit. Run out after watering is even more important with salt nutes than organic bottle stuff.
I noticed Canna doesn’t mention plain water/super mild feed once a week, which was a cardinal rule 25 years a go with salt based nutrients. Same with many other companies too, they don’t talk about salt build up even thou they recommend high EC levels with their salt nutes.
I use bottled organics in soil and still i give plants plain water at least once a week and these won’t build up in the soil as fast as salt nutes do, but organic stuff also cause build up in the medium
If you don’t water so that you see run out..
It got me thinking that is the medium moist enough right after watering? and that part of the yellowing could be caused by underwatering
So when the plants need watering start giving them a larger amount so that you see nice run out off the bottom of the pot. This way they the plants get a large enough drink and the medium gets washed out a bit every time
So first thing is to give the medium a little flush with plain water and once you’re done flushing give them a feed that is 50% of the normal level . Allow the soil to dry little bit before next watering so you won’t run into root rot issues right after flushing
It’s probably largely caused by the salt build up that your plants got over fed and are quite dark in color but landrace based genetics and also Skunk1 don’t need a feed that is very strong, they’re mild (hades) to mild/medium (skunk1) feeders. So maybe you can also cut some nutrients out of the feed, at least 25% of what you’re feeding now
Having the nutrient solution mild enough also prevents salt build up in the future
If you use the full amount of nutrients, as Canna recommends in their feed chart, then you can probably cut 1/3 of that amount , maybe even little more
To give you an idea, If we talk EC numbers, Hades genetics would do just fine with EC of 1.2 or so - The Skunk1 in the EC 1.2-1.4 range.
But Canna’s chart has maximum EC of 1.9 – 2.3 so at maximum strength it’s almost double what the Hades actually need. Do some calculations on how much you can drop your nutrient strength but i think it can come down little bit
I hope things look better in couple of days
