All I will say is whatever route you decide to take just dont get discouraged when things go wrong because they will. If you stay with Hydro the most important thing you need is a good reliable and waterproof PH meter. PPM meters are nice but not as important (IMO) as a PH meter. I grew for well over a year without PPM meter and all was fine using a tried and true formula and watching how the plants reacted to what they were giving. All growing really is (IMO again) is being able to read what your plants need. Lastly dont rush things. If you have been vegging plants for 3 weeks and they look like they could use 1 more before flower then give it 1 more. Dont just jump in and say well it's been 3 weeks and I was told afetr 3 weeks start flower, thats only if plant is where you want it to be at that time. Have a nice day and welcome to the world of Cannabis :jointsmile:
