How often should I top? Also, when should I apply the low test stress on plants? Is supplement like big bloom, a good supplement to use for better yields?
You can start training that one now
You should have filled that pot up with way more soil bro
Thank you, for the advice for next time.
Actually now is the time, if you have a spare pot just transplant it into that with addition mix.
Welcome to the community , Photo plant I like to top one time at 8 or 9 nodes. Healthy looking plant. Keep up the good work . (Big Bloom more for flowering)
Depending on the size of the root mass (pot size) there will be a limit to how many times you can top. IME if you top too many times you don’t affect yield but all of the flower will be smaller.
I generally top once at about the size you’re at now. Then I do a round or two of supercropping and HST with my photos. If growing autos you really can’t do anywhere near as much.
I only top once…around week 3. Then i start LST at about 5 weeks. At week 7 the trellis net goes in and i do my pre-flower pruning. Seems to work well for me.
