White Widow Auto - First Real Grow

Day 15 - I added a small oscillating fan to get the air moving in the lower part of my tent. I moved the light to 19/5 to give the plants a little more rest since they seem pretty stressed. Today makes 8 days since I watered and they aren't showing any signs of getting thirsty yet. Soil still feels moist just a couple inches down. I'm thinking the little bit of yellow that plant 1 is starting to show might actually be the beginnings of a zinc deficiency which could be caused by root stress which can be caused by over watering. So when I do finally water I'll just throw some Recharge in there and see what that does. No nutes yet. Plants 2, 3, and 4 are still stunted but they're giving me hope that they're going to recover from the over watering. They weren't doing much for a few days and now their growth is noticeable every time I check on them. Plant 1 is probably doing better because I didn't give it as much water from the spray bottle early on. I was afraid the seeds that hadn't made it to the surface yet needed to be sprayed far more often than they actually did. So the longer they took to make it to the surface, the more water they got. Plant 4 must have been drowning. I haven't seen any sign of a fungus gnat in a few days so I'm guessing it was just one that managed to fly in through an open window. Fingers crossed. I also got a new (expensive) pH meter and after cross-checking it with four different methods my cheap pH meter I've been using is actually accurate. --- Day 19 - I finally had to water on Day 16 when plants started to show first signs of thirst. I had to go out of town for a couple of days and I got home to a lot of new growth. At this point my plan is to LST plant 1 and probably leave 2, 3, and 4 alone. The internodal growth on plant 1 has more competition than the other plants. We'll see what happens though. --- Day 21 - Plants were showing some signs of thirst again so I watered them with nutes because the deficiency I've been seeing that I thought was zinc is probably a magnesium deficiency. The lower leaves are thick and crispy in addition to that yellowing. I started LST on plant 1 and I'm probably going to have to start to LST plant 4 just because it's twice as tall as any other plant now. Plant 3 has absolutely entered flowering and it's definitely female. Do autoflowers usually flower at different times or is it strain/breeder dependent? I was planning to harvest all of them at the same time and dry them in my grow tent but I think I'm going to have to get a harvest tent if they're flowering at different times. Oh, and I opened up the humidifier to refill it the other day and there was a dead fungus gnat in the reservoir. I haven't seen any since so maybe it was just a loner. More pics tomorrow.
