This timeline is probably wrong as I lost track after the vacation, nutrient issue, other plants etc. but you can see they're all "recovered" as much as they can be!
I suspect the one plant with more curling/yellowing/burning leaves is still having those issues because I defoilated far too much and too far into flower. I went a bit crazy after the calmag thing and got rid of all the yellowing/brown leaves and since that one had it the worst, that meant all the fan leaves basically lol. I also think she's a bit rootbound compared to the other two. The 5gal plant is fine af, and the other 3gal is basically chillin' but smaller. The burned girl (jesus christ smh) also doesn't smell as potent as the other two, almost like grass really...but none of them are CLOSE to the outdoor plant of the same strain. It's insane lol.
Temperature is very hard to control in the room the tent is in, but I figured out a way that works for me to keep it always under 83. Humidity was skyrocketing after watering but I just open the "windows" to the tent and it stays around 65% for a day or two, then I empty out the water from the bins and it's back to 55-60%. (they don't sit in the water, they're on risers).
Lots of people keep saying these recent Northern Lights Auto Flowers are taking much longer to finish, and I have to agree. The mini microscope is showing em all as clear and only slightly cloudy with a random amber head here and there. I even saw a new bud site underneath some of the flowers! I think they've got random spots of veg growth and stuff...the autos really are kinda weird lol.
@Rock_n_Roll_Randy, thanks! I think it's safe to say it's been pretty fun so far, especially with seeing the effects of the LST. I'll make it more aesthetically pleasing next round since it's hard to see what's what when it's all over the place.
