LSD-25 Auto: Tropical Grow

First of all, I'm in an overseas location with severe penalty for growing or possessing. I was anxious, to say the least, about getting seeds here. I had a previous Lemon grow using primarily whatever I could get my hands on. I do have Humboldt's Secret, a great fertilizer. My yield was low but adequate then from two plants. I'm only looking for personal use stash and thus I'm putting up four LSD-25 Autoflowers this time around, enough to provide me eight months of yield. I cannot get Fox Farm soil here without huge expense so I blend my own with a mix of soil-less, vermicast, rice hull, etc. I have a shack where I set up a grow arrangement utilizing a KingLED 600W for the first two weeks, then switching to the KingLED 2000W for the larger footprint and added illumination. Now I'm on a 20/4 schedule roughly and use a fan on constant flow to move air adequately. I am trying to maintain a feeding ph of 6.8 and have been using my swimming pool as the initial source of water versus using tap water here with large amounts of TDS. Before you yell, be it known that my pool is bionized utilizing copper ions and has no chlorine whatsoever. It's drinking quality and the plants seem to like it. 😁 The first two pictures in this diary show the ladies outside for the first time. (nervous Dad here). I moved them out to allow run-off after watering each of the 4 gallon pots thoroughly, one gallon of water only each. I had previously been watering only in the close proximity of the stems to feed the young root systems. Seeing the spotting on the leaves of one of the larger plants made me think I'm watering incorrectly or that I may have overdone the nutrients. This pics are also just one week after transplanting them. I know now after reading up that Autoflowers should be started in their final pots due to the lessened grow cycle. Surprisingly, the growth wasn't affected in the least, or so it seems. So.....they're heading back inside later this afternoon. I hope they've enjoyed their day trip and don't bring home any unwanted visitors with them in the process. I treated the outside of the pots and the surrounding ground areas with Neem Ant Spray prior to bringing them out. I'll give them a foliage bath of Neem Foliar spray tonight before putting them down for their nap too. Pests are extreme here as is extremely high temperatures and high humidity; all of which I can do little to compensate for. It will be a struggle to make the best out of these conditions. I gratefully welcome any advice or comments made for my grow and I'm hoping someone can shed some light on the source of the spotting on the plant pictured. Thanks everyone for reading, I'll post pictures next time showing the primitive grow room that I've put together for lack of something better. It will make you chuckle.
