I have a couple LSD strains 20 days since sprout and am looking into when I should top them. My plant has 6 nodes with a 7th on the way. Does the first set of leaves (the 1 leafers) count as a node? How developed should the top nodes be until I top it? I am wondering too if cutting above the 3rd node rather than the 2nd would still result in 4 main colas? My bottom 2 leaf sets seem weak so does an extra set of leaves help much? Also, after the top is it necessary to veg longer? and How far behind would the tops be behind the plants if I decided to clone it? any advice/tips are welcome.
