Stunted Seedlings

I've been having problems over the last few years with feminized seeds. I get close to 100% germination, but half the time the seeds don't grow past the first few
leaves. I even have one going now with 3 oval starter leaves(cotyledon). Am I getting hermie seeds? I buy top quality well known strains. Most of these seeds come
from respected seed distributors. I was thinking they might be getting irradiated, but I don't know. I think I'm going back to regular seeds. This is really frustrating and time-consuming!

Could be your water and or soil...... I imagine you have already tried different kinds. good luck

Thanks, but I always use spring water and rockwool starter cubes. I've used the same type of small hydroponic all this time. I can't think of anything
different other than the seeds. I even tried going with soiless organic mix and the same thing happened.

try planting in soil and ph your water every time. gl

Hermie seeds?

Sure its not something you are doing?
