Auto Sasha's Legacy (Low Rider #2 male X Purple Rider female)

Germination of 39 regular seeds from the cross of Purple Rider x Low Rider #2. The cross was made around 2007 or 2008 and since then it has been improved in search of precocity and size. It has two very different phenotypes in terms of appearance, one that resembles the low rider, smaller and with more robust flowers and dark green leaves, the other phenotype however is larger, with light green leaves that turn a reddish purple tone. The smell, taste and effects however are identical. Of the 39 seeds placed to germinate, 38 opened and 36 went into the pot. The goal is to have 16 plants flowering in 7-liter pots. I separated the earliest one in an attempt to hermaphrodite one of them, I used 300ppm colloidal silver for about 30 days after identifying the plant as female, twice a day. It didn't work, it didn't produce a single male flower. If anyone can help me with tips on how to hermaphrodize I would be grateful. I've been struggling with this for a while. My lighting setup was a Quantum Board Samsung Lm301h 120w LED panel plus a Quantum Bar - X55 - 240w - Samsung LM281B. The soil is a combination of reused soil, topsoil, organic compost made by myself, Bokashi, ash, limestone, vermiculite, coconut chips, and coconut fibers. No fertilizers during germination.
