I have two regular photoperiods that I started indoors in April. 3 months old now, and the first little pistils are showing. Is there anything to add, specifically to strengthen the stems? I’ve grown autos inside, they have much stockier branches.
I have used organic fertilizer and worm castings through their life.
Your post was stuck in a “pending” queue that is difficult for me to see, so it was never approved to be seen until now. Sorry about that. This post is from several months back but shows as today since it was approved today. Beautiful plant! Calcium is well-known to help build strong cell walls. Also Silica is a non-essential element that can help with resistance to lodging (falling over).
