Thanks, Flower Child.

If it's that simple, I'm surprised I havent seen it before, but I dont know of many resource sites to look up information frankly.

So theoretically, after some number of days on plain RO water like I have been for a few days now, I should see PH stabalize, then turn towards rising. I'll keep an eye on it. At the first hint of rising, I'll consider a weaker diet for them.
MisterE Reviewed by MisterE on . PH Dropping quickly? I'm sorry to post this question, I tried to search but the term "PH" is too short for the boards search function... I'm having to PH Up my nutes more frequently as my plants grow. I'm wondering if this is considered normal, or if it is indicitive of any actual problems etc. I only use 8 to 10 gallons or so total (going to change it out and measure carefully today) and the plants are only about 10 inches tall, on their 8th node. I calibrated my continuous meter yesterday, and PH Up'd to Rating: 5
