Remember your plants will double in size so you need to calculate your height once you switch to flower.
Nitrogen is VERY important in the beginning of flower, during stretch. If you give too much PK in the beginning you will lock out calcium.
Dyna-grow is exelent however it isnt nateral or organic. 100% sinthetic salt based. Try Roots Organic or General organics. If you do go organic i would suggest lots of microbes
Lol i mentioned that in the first commentAlaska fish fertilzer hasn't been made in Alaska for years and contains all sorts of toxins and heavy metals. Somewhere on the bottle it likely says, *not for use in organic food and crop production. Because it's made in indonesia out of polluted fish and shellfish crap.
The first True leaves are the first serrated ones that show up after the cotyledons. The little round ones that first show when a seed sprouts. They are supposed to go yellow and die off.
Dr. Earth doesn't have slow-release nutes, it's organic. I like Dr. Earth, of course. But slow release implies controlled release synthetics.
Where? Cotyledons are not true leaves.
I say right there the first TRUE leaves fall off. made no mention of the seed leaves
