Harlequin (Fallponic RDWC)

WEEK 15 - 30/10/2021 - 5/11/2021 1/11/2021 - they are not drinking much, ec is static and the pH is decreasing drastically. I have to bring the pH up to 6 and the next day it goes down to 5.4. I thought it could be due to the second air pump causing high co2 in the res which lead to acidity. I turned off of the air pump and yet they are not improving much. I think I might need to do a flush before doing a complete res change. Sigh... 3/11/2021 - the buds look about the same and not much bulking up. And the branches especially on plant 1 look shrunken and dehydrated. So the plants are leeching out water! Never seen a dehydrated branch before. But why? There is no reason for it to do so. The EC is within acceptable range for late flowering plants. I do fresh res mix weekly. The nutrient element ratio is also within the recommended range. So why?? Flushing seems like a good idea now. I'll be flushing with Florakleen for 24 hours before mixing in a new batch of nute. I mixed 15 gallons of water with 170ml of flora kleen. ph at 6.13 and ec at 0.06. 4/11/2021 - 25 gallons of water mixed with the following: Cal-Mag - 2.5ml/gal - 63ml Micro - 2ml/gal - 50ml Bloom - 7ml/gal - 175ml Hydroguard - 2ml/gal - 50ml pH - 6.12 EC - 0.88 mS/cm T - 24.0
