When can I start mainlining the first plant is it okay to cut the top now or do I wait a 2weeks more? Bigger plant has been vegging for 2weeks and the smaller one for about 1week and 3days.
You can find a mainline guide around here with a search and it will explain all. Soil compaction/poor aeration, pot size too big, soil always damp >slow root development could be the reason/s if you think you have slow growth.
My opinion if you care for it, mainlining is over rated, slows growth down a hell of a lot and will be even slower(or worse) if you also have root development problems.
