Hey GC quick question for you guys. I am having trouble getting my water & nutrient solution to a good pH. The water is pH 7, but after adding my flower nutes the pH drops down to 5.2 [I am only adding 1/3 strength and its week 6 of flower] Last time i watered i was in a hurry and i was able to dilute my solution with more water and got the pH to 5.6 and didnt have time to do anything else. I think i might be having a bit of a lockout because some of the leave on my cola are yellowing, so i need a way to raise the pH of my solution that is safe for my plants. I have read I can use 'potash' but i dont know where i can find that today to use it. I also have read that you can use Baking Soda to raise the pH, but is that safe to use on plants? Any help would be great, I have about 7 hours to figure this out! Thanks!
