Yellow leaves....every time

Every strain of every pheno I've ever had I get the same result. The first 2 sets of leaves get yellow and necrotic. They are in happy frog right now. Sometimes it even goes up further. They seem very healthy. Huge root systems. Enough water. Not nutrient burns. And the bud is some of the best I've ever seen! Can someone explain why this only happens to me and how to fix problems with my leaves

i dont entirely understand the question? sooo wheen there seedlings this happens or what?

It's right when they get their first sets of fan leaves jswett1100

Maybe change your starter soil to something that doesn't have any nutes in it and then transplant into happy frog. Your burning seedling at that age with that soil. Next time use peat,verm,perlite starter mix and youll be fine.

too much light will hurt seedlings. Some time the plants will use the n in the leaves to supplement new upward growth, A soil that is high in organic material might be causing this also. I use a hightest pro-mix and every leaf including the seed leaves cotyledons stay green until they are ripped from the stalk by fast growth.

I'm about to transplant to a 3 gallon pot. What should I do about soil to avoid yellow leaves. They're at about 3 weeks. Or should I stay with happy frog?

The first set of leaves being the little round ones? Sounds completely normal to me. They have served their function and the plant lets them go. Not sure why you think this only happens to you?

Happy Frog is fine for seedlings....I use it all the time. It's not "too hot".

Not the little round ones. The two sets of leaves after that
