First grow in new house. Trying different styles. Main strain: OG #18 and Headband

Recently moved into a new house so I now have a whole room to play around with. I still started everything in a decent sized closet as I plan to keep using it for vegetative and use the big room for flowering. As of now I have one 3 week old sharks breath in a 5 gallon pot of soil and a cole train in a 5 gallon pot of soil. A friend gave me a chem d seed which I popped in the small container to the side in the pictures. I also started to germinate a og kush #18 from reserva privada, a headband from reserva privade and a bubblelicious by nirvana that I got a hydroponic system I am going to run them in. Next week when I make my trip to the store for new flower lights I will also go ahead and pick up 6-8 new 5 gallon buckets and some fox farm line products to start a couple of new strains. Haven't decided which ones yet but I have these to my disposal.
Og Kush #18, Headband, Sour Kush, Sharks breath, Cole train, Wappa, Sensi Star, Warlock, Rocklock, Sour Cream, Blue venom, Chronic and Motavation.
I am going to grow at least 2 each of the OG#18 and Headband in 5 gallons. I will be using 1000watt aircooled HPS tubes for flowering.

The cole train plant I have, unfortunately is sitting in some cheaper soil, and I think I over watered it last week. One or two of the top leaves are curling inwards (look at 4th picture). Is that due to overfeeding or too much heat? The room stays around 78-81 and the humidity at around 40%. I have a humidifier I can add and also another cooling fan if necessary. Any suggestions?

Thank you all and happy growing!

I will be doing 3 plants in the hydroponic system (OG #18, headband, Bubblelicious) And I will be doing a total of 8-10 soil in 5 gallon buckets. 2 OG #18. 2 Headband, 1 SharksBreath, 1 ColeTrain, 1 Blue Venom, Sour Kush/Sensi Star. I am also thinking about setting up a DWC system to try it out.

Cool, glad to see you started the journal on both. I'm at the tail end of doing the same thing of growing in both soil and hydro and its amazing how busy one can keep juggling between them both. Best of luck and I'm sub'd.
