My last run of autoflowers has been a terrible failure. Before this I had no problems getting a decent yield. I think the problem may be with my soil (basic potting compost mixed 50/50 with perlite) Before I used cheap potting soil too, but a different brand. It seems that overwatering is occuring, I cant even do a full water at 4 weeks, it has just curled up (previous to that I was giving a few squirts at the base every day, this was fine they plants looked OK).
None of my plants can establish a proper root system, some only reached about 3 inches down into the soil, and produced 3-4 inch high plants at 4 weeks. Also many seedlings just die off with a 1 inch tap root, its as if the roots cant penetrate very far into the soil. I reckon I have had 10-15 seeds fail on me (they all popped fine in wet kitchen towel before I planted them, but as soon as they are in the soil they dont seem to get going very well.)
So I am looking to use the canna Terra Professional Soil Mix. I just wonder do I need to mix this with perlite? If so, how much? It says it has perlite already in it, but drainage is obviously important to get this overwatering problem under control.
I just wonder how I should use this soil to promote good root growth? IF anyone has any experience with it I would greatly appreciate your input. Thanks.
