Hey man, I'm growing red poison myself too, I had a question if the stem of your seedling is purple. The stem of my Red Poison seedling is purple and I was just wondering if it was genetics or my environment that's causing it.
@@badaboopbapow, Hi man how are you
At this stage of growth a purple stem and often a sign of a poorly regulated ph problem
Your ph for growing cannabis should be set between 6 and 7
I set my ph to 6.5 between the two
And you will see that your plant will absorb nutrients better
Too high a ph risks blocking the passage of nutrients and you risk getting a lockout
I grew 2 Tropicanna Poison, my 1st had an 80% phenotype and on the 2nd no phenotype, on the other hand a lot of trichomes
On Red Mandarine no phenotype, a magnificent plant despite the lack of purple red
You can see from the pre-flowering stage if there is a red phenotype on your plant
At this stage of growth you will see nothing man
