Hey all

This is my first complete grow (seed to flower) and 2nd time overall. Was hoping I can get your opinion on the photos. Looks like the first set of foliage is starting to yellow. Is it Nitrogen? Been doing a lot of reading over various sites and even have the bible (Ed Rosenthals guide) but I'm narcotic when exhausting options.

Bit of history:
3 plants germinated from seed
Plants are entering their 5th week
Organic soil medium (golf green organic compost with black earth)
feeding it filtered water
I did spritz a bit of nutes (General Hydroponics 'Grow'), this past Wednesday (04/22). 1/4tsp in 1 litre bottle, but maybe used a tenth of the spray because they are young plants and there should still be nutes from soil

I should note that it's only the one plants lower set that are slowly turning. Noticed this yesterday (04/24).

looks like rich soil but lack of drainage in it.You should leave them dry longer and when you transplant add something like perlite,zeolites or other to improve the drying and provide more oxygen and ease the roots to grow.

Thank you for the feedback. I thought I was missing something when I mixed the medium. I was also thinking fabric pots down the road.
