They look lovely and frosty and plenty of bud sites them buds will start to fatten up nicely, I must do a Barney's pineapple Express I really like the look of them bet they smell amazing, you are doing a great job.
Got some lovely stretch on those colas though, im sure theyll fatten up for you though, your other plant is going beautifully so sometimes you just have to accept that you didnt quite get the best dominant genetics in a seed unfortunately, ive seen PE autos all grown in the exact same conditions where one plant was 4x taller than the others haha
never grow an auto but from research you honestly don't have much control over autos as they do what they want and finish early. some produce only 7g and never get big when another from the same bag of seeds produced 2oz. I like my regular seeds as I can control the plants & them not control me. but I'm still interested in doing some autos myself to make my own strain.
@Letgetit, I've had good luck so far. My first 2 plants were over 35g dry each. My second 2 were 2oz dry each. (I think my 7 gallon bags are a good size for root development because when I pulled the stem out of the bag to chuck it the roots were filling the whole pot on each one.)
