Alaska Comeback Story

There are many many variables that can determine the size of your plants, genetics, pot size, lighting and so on, they don't look stunted to me and they look healthy and thriving to me...Just keep doing what your doing BUT if you feel as though they're stunted or not as big or want to do more, I would increase the intensity of your light if possible, move it closer but your going to have to make sure your DLI is on point as well, RH and temp..You can download VPD buddy to get your parameters

You want your pH to be set after additives. It’s all about the pH when you input the feed in the medium

I like how yan402 thinks, however I was told no direct light should touch the floor of your tent/medium or its wasted wattage. always a leaf catching something. the whole process of defoliation is to increase airflow between bud sites to prevent budrot. If you got good airflow and fans penetrating the canopy moving air past everything I would not worry about it. Getting extra light to the lower buds is also good but unless you supplement with under canopy lighting its never gonna be all that even with defoliation. The sun can do some of that. its much more powerful. Good Luck!

Na man I think you’re fine. It is a sign of overfeeding but I see it slightly on almost all my grows in flower. You want to push it right to that threshold of being too much IMO.. just keep an eye for other signs going forward and monitor runoff to be sure.
