White Widow Auto - Double the Trouble

It's been two weeks since I applied the lime to the soil and things seem to have improved overall, just not as dramatically as I had hoped. The leaves are looking pretty yellow but the bud production has increased fairly substantially. The grow light makes things look a lot more yellow than they are under normal lighting so I'm regaining a little cautious optimism and I plan to see this grow through to end. I was worried about all of the Cal/Mag Plus I had dumped through the soil so I got a flushing agent and flushed every plant. Run off pH is now 6.3 for every plant but 1 and 5. Run off TDS was around 400 to 650 for every plant before flushing, even plant 4 which had never been flushed. Fed them all at about 500 ppm, and run off after first feeding was about half of what it was going in so I'll give another full feeding next watering and hope it keeps them happy. I watched a video and learned a bit more about lighting and I'm going to try to keep the brightest part of the canopy at 650-700 PPFD. Because the light is on for 18 hours with autoflowers, you get the same DLI at lower light levels as you would running 1000 PPFD for 12 hours. Most lighting advice you'll find for cannabis is assuming a 12/12 cycle in flower. I also started adding a tiny bit of epsom salts to every feeding. I learned that sulfur is responsible for terpene and flavonoid production so I figured adding a teeny tiny amount of epsom salts to every feeding couldn't hurt. Plus, plants 2 and 5 are showing what looks like a sulfur deficiency so they got a little more but they'll be getting the same amount as the rest from now on. I'm going to let this grow go until I see some amber trichomes this time. Last time I didn't want a single one but this time I want more bulk. I'm assuming that means it will go about a week longer than it did last time and I'm planning to flush about 5 to 7 days before harvest so I've still got a couple of weeks that I can feed them and give them proper light. Harvest isn't going to be ideal but it's not going to be a complete waste of my time and energy like it felt a week ago. I seriously can't believe plant 6 is still alive and producing buds no less. I also wanted to mention that plant 4 is doing the best as far as bud production but the leaves are so dense I'm really worried about mold. So, I put my harvest dehumidifier in the tent and at this point it's been able to keep the humidity around 55% when the light goes out which should be low enough that mold won't grow. It would be a shame if the “best plant” had to be thrown away.
