Hi Tomaz, thanks for your comment. I'm sorry you haven't had much luck growing purple flowers so far.
The main factor in getting purple weed is the variety that you choose. I've never tried Red Poison or other coloured genetics from Sweet Seeds but I had great results growing Violeta from ACE Seeds, every single plant from the pack I grew had very dark purple flowers and amazing flavour.
Another important factor in getting colourful buds is the temperature during flowering. Lower nighttime temps will provoke the production of anthocyanins which are the compounds that give the colour, so try lowering the temperature in your grow space during the flowering period and try to aim for a 10-15ºC difference between night and day temps.
The third factor to take into consideration is the type of illumination, which can also influence the colour. A friend of mine switched from HPS to LED recently and he's been amazed by how it's brought the colours out, a very notable difference.
I hope that helps, best wishes and happy growing!
