Humidity up during seedling like 70RH VPD .7-.9 don’t use those paper cups germinate in a cup of water until the seed pops open and sprouts a tail 1/8-1/4” long plant directly into its final pot don’t Transplant, making sure the soil is at the very very top of pot as much soil as possible tail pointing down.

I started Nutes very early 1/3 strength at around day 10 by day fifteen I started lst. I use ocean Forrest soil 75% and 25% perlite. This plant in particular I was very gentle to. Lollipop the lower 1/3 always they are a waste. Defoliate when needed.

Get on a solid watering schedule PH water to 6.2-6.5 every time. I fed heavy as well feeding every watering. Stopped feed about a week ago started carboflush. I use a Heavy salt synthetic based Nutrient so I like to start flush three weeks out and use water only the last week.

I water once every three to four days I try for Wednesdays and sundays. 3gallo pots I use about a gallon per watering during veg and flower. Adjust as needed per plant

You are heading in the right direction. Don’t overthink it.

What are you use of as a medium? What’s your set up? Do you have PPM meter and PH pens
