Currently running my first grow with happy frog living soil in 5 gallon pots (85% soil, 15% grade 3-4 perlite) at 35 days since sprout on mars hydro tsw-2000 (300watt). Plant 1 and 3 started showing pistols a week before plant number 2 and the bleached tips on plant 1 are because she is the fastest vertically growing plant. Currently sitting at a vpd of around 1.2-1.25 day and night, daytime temps between 75.5-77F nighttime is 71-72.5 F, humidity is between 60-61.5% and at night 56-58%. Attempted some LST and planning to do trellis once they get to about a foot tall, at about 10 inches for plant 1, 9 inches for the other 2 plants. They have been watered normal tap diluted to 150-200 tds and phd to 6.4-6.6, at day 15 scratched in 2tbsp fox farms general purpose and 2 tbsp fox farms bloom and flower dry amendments, at day 42-45 we will do our last feeding of 5 tbsp fox farms bloom and flower dry amendments. The white dots on leaves are from humidifier using the high tds diluted water, I ain’t got time to buy gallons of diluted water a week so it is what it is.  
Not sure what plant number 2’s problem is either her leaves are too big or if im over/underwatering, or if its something else they get 250ml (upping on next water) but she looks droopy every time i water before and then she perks up for maybe a day, and then shes just droopy all the time even if i give her extra dry down time, no pests noticed on any plants and her top growth looks healthy and new growth looks healthy but her main fan leaves make me feel like shes sick
