First Grow Ever - Humboldt Seed Co.

Being my first grow, I wasn't sure about light strength. Kept the light at max height, 25% power while seed were sprouting. Turns out that was too little and the sprouts stretched quite dramatically. Light was adjusted and now I have PAR meter, so seedlings are sitting at ~300ppfd. Had typical 'seedling anxiety' checking them every 20 minutes and searching the internet to look for non-existent issues. Learning to just leave it alone. This first week fed with cocoforcannabis feed mixture for seedling. 6.3 pH and 407 EC for the first couple days, but the mix drifted towards 480 by the end of the week. Only have the one big light and tent so it's pretty inefficient to grow such tiny plants in here in terms of light/humidity, but it with have to do.
