The plant with no lst in the 7 gallon pot seems to...

Hey there all plants are going to turn out different, you could do 3 of the same bag of seeds and still get a mixed report. As for fattening, if you're trying to keep it relatively natural you can add a couple tablespoons of molasses to your gallon of water and it helps to sweeten and fatten, and since its giving a natural sugar to the plant its not essential to be flushed out like other products. Being an outdoor grow, are they getting at least 5 hours of direct sun?(hopefully more) As for the larger pots, I think they would just have an affect on how often you need to water and retention of nutrients. I've been told the bigger the pot the better, perhaps this isn't so with the autos. Also LST is probably a essential aspect for the autos since your means of training are much more limited. Happy growing. I hope they bulk up for you.

As Athos said genetics play a huge part in what a plant looks like. But Afghan is not a dative, In this case it’s the rudarelis geneoptye. It’s happened to me on autoflowers in the past. https://sites.google.com/site/cannabissamen/cannabis-ruderalis?tmpl=%2Fsystem%2Fapp%2Ftemplates%2Fprint%2F&showPrintDialog=1 Here is a link to an article explaining wild ruderalis, look at the 2 images that you see straight away, notice the sparse bud structure. However nothing to fear, although the yeild may not be as great as you could expect from a different hybrid. The quality may be up to standard. A plant that I had a few years back as I said look just like yours, I wasn’t expecting much from it, the effect was incredible it was the strongest of the 3 seeds I grew! Good luck, hope this clears it up for you😜

I think you might have foxtail buds. This could have to do with genetics and is not that bad since they say foxtail genetics could produce more thc but it could also happen under a hot environment! You could read about your plant genetics and check if she can develop foxtail due to genetics. Either way you have a couple of weeks left and buds can still get fat! I have read that cooling down a few degrees during last weeks of flower fatten the buds!

Hi, You're not near the end of harvest yet, you still have quiet a few white hairs showing too. When they have all turned orange/brown colour and pulled back in you can re-evaluate the situation. But as of now you're on track and have nothing to worry about. Your buds are still in the process of fattening up, be patient and it will reward you.

Some strains (specially those whose genetics have a more sativa disposition) have long thin colas. That been said, Most of the weight of the buds is gained in the last two weeks, you still have some weeks to go, don't fret.
