First grow! Come check it out!

Hello @beer420 ! You can top autos. If you are going to top them you need to do it after the fourth node, not later or sooner. For your question if its worth my answer is not, at least for me. I have constantly better results with other kinds of HST and LST training. Happy growing ! :facepunch:

That's called clawing, it's a sympton of excess nitrogen (over feeding) like the burnt tips that can also be seen on some of your pictures. Let the plant feed from the soil and stop feeding it for now. The purple stems could be due low temperature, try to get them above 23°C (73°F) or magnesium deficiency, but before rushing to buy anything, keep in mind that excess nutes can lockout minor elementos like magnesium. So stop feeding, rise temps and see how it goes.

Hi @beer420! To me it looks like the result of a serious Nitrogen toxicity My theory is that a wrong pH range for the whole grow (and probably a wrong watering routine) have created some sort of salt buildups and/or Nitrogen toxicity due to the use of EasyGrow, and the roots can't handle anymore. This is confirmed by your leave's coloration, this dark greeen is a bad sign, especially when it's glossy like that, your plant had too much Nitrogen for the last weeks. In this situation I would remove the most affected leaves, heavily flush the medium with plain pH'd water (~6.2), put a tiny fan blowing onto the container to help it dry quickly and avoid an overwatering scenario, then see how it goes after a few days. If things are looking good, consider giving some P+K booster for the last weeks before the final flush. Now about the watering routine, make sure you follow a wet/dry cycle with quick rotations, I.E one day wet with nutrients, one day dry, one day wet with plain pH'd water, etc...And always water with ~15-20% of your container's volume, unless you want a serious drain (in order to flush). Hope this will help, keep us up-to-date, and happy growing :facepunch:
