You'll need to consider the size of the plants in 8 weeks to the amount of space you have. From your video I'm guessing you have 8 plants in a 2'x2' tent. There are more than 1 factor here to consider, i.e. are you transplanting to bigger pots etc... 1 plant can easily fill a 3'x3' if done right in 8-10 weeks. In your case its more like a SOG than a SCROG. You can safely say your plants will double or more in size during flower therefore that might help you to estimate if you have sufficient space. Considering your tent size and all you would almost have to switch now but LST your plants today so you can have more cola sites. Best of luck and don't worry your tent will be jam packed lol.

So basically from what I can see in the stats is that your PH isn't quite at a suitable level for your plants to absorb all the nutrients and micro nutrients they need . In a soil medium your plants will be happiest in a PH range of 6.5 to 6.8 . Given that your PH is 7.3 you're currently locking out important nutrients your plant needs in order to really flourish . I would advise that you lower your PH slowly over a couple watering to prevent shock . Lowering your PH to quickly will sometimes lead to stunts in growth and at this stage that's not what you're looking for . I might also suggest that you give your plant(s) a good dose in the nitrogen department . Not a whole lot but just a little bit so that those yellow leaves can go back to a nice lush green and I do mean very little at this point its almost pointless but it would help your plant stay level . Other then that I might suggest adding a little CalMg to your mix , this is basically the essential building blocks for growth , your plant(s) will burn through it quickly at this stage of growth and if it dont have enough it will suffer both in resin trichome production and swelling of the calyx ( the flowers ). I hope this information helps you on your journey ! Happy Growing !
