Okay guys and gals, I'm new to this hydroponic business so I need some help, maybe a lot. I've been told that there is perhaps (because of claws) there is too much nitrogen in my watering system. How do I test it for my ph level is 6.5? How do I reduce the nitrogen, cut back on the nutrients? What? Thanks for your help.
Wow - this is my favorite question of all time so far.. You can't reduce your hydrogen but you can increase your hydroxyl ion concentration. I would suggest Sodium Hydroxide, or baring that Sodium Bicarb. You can use several methods for pH testing .. strips, solutions or even meters. Also - I would suggest you read everything you can find on this web-site before you start growing.....
I must have my head up my you know what. Sorry about that. I should have wrote nitrogen, not hydrogen.
That's OK! It was a great question - I laughed for at least a minute You want to reduce the N in a hydro system add more water. If you are asking the question you must me having really dark green leaves. I really slam the N on my plants and unless you are showing obvious signs of burn you should be OK. You got a PPM / EC meter? That will give you a good idea of how much water you might want to add. Worst case - drain by half and replace with clear water.
