PH Drop

  1. Hello. I am looking for some knowledge regarding PH. 3 Green Crack, 3 Purple Kush. All 6 Plants get the same Nutes ( Humboldt Nutes 3/4 dose, Dynaguard 1/2 dose ). Problem is I have 2 Green Crack that drop PH from 5.8 to sometimes less than 4 overnight. I would like to add that all 6 plants get the same amount of nutrients. Buckets are scrubbed each week with nute change. other 4 plants are fine and don't fluctuate that much. the 2 I'm having the problem with are the most mature and I'm ready to flip to 12 12. Has anyone seen this kind of behavior before. Is this normal. if not what would the solution be. I'm open for suggestion. Thanks for reading
  2. Water naturally drops pH after it sits out for 24 hours go ahead to amazon and get pH up remember to experiment with your water when you first get pH up anyway good luck!
  3. I use ph up and down. I ph the water to 5.8. 2 plants will drop from 5.8 to below 4 overnight. Today during my water and nute change I left out the dynaguard. After 8 hours the ph is still close to 5.8. It might possibly be the dynaguard and mature plants. I don't really know. I will have to see if there is a change in the morning. Thank you for taking the time to answer my question. That was very kind of you
