You shouldnt take much notice of trikes till you can grow healthy happy plants, if your asking why leaves yellowed or its taking a while to finish or a loads of other problematic stuff then your trikes wont be able to tell you a clear picture and yor best of just going on the buds look like calyx and pistols.
Once your plants are finishing on schedule and looking healthy you will see the trikes show a clearer picture. At this stage some may want a bit more amber sone less and just looking at the bud dosent give the fine details.
Once you have seen all this and tried every type of trike you seem to get bored of looking because it dosent make a hell of a lot of difference over just looking at the calyxs and pistols.
Someone hears about trikes and scoles and thats the first thing they try, so much easier to start with just learning the calyx pistol system and what done is looking like.
