was the new nutrient solution you made stronger than before?
did you check to see if they ppm level has been dropping or raising?

if pH is dropping, and the ppm level is raising your plants are overfed

my suggestion is to run nothing but pH corrected water in your system and keep monitoring the pH, and don't add nutrients until the pH is stable and new growth has resumed

and if the nutrient mix is too hot right now at its current ppm, then needless to say don't have it that high when you re-add the nutrients after the flush

just my suggestion
hopefully someone else will post to help you out as well
Illusion Reviewed by Illusion on . Ph keeps dropping ...!!! help I started my grow in 8x8 inch pots on a 4x4 foot flood table ...when I switched to flower I also switched over to 5 gallon bubble buckets ....they grew very well after the 3-5 days it took for them to get over the transplant shock. But I have noticed my ph levels are propping drastically ...I just changed the nutes Saturday in the buckets and by Monday night the ph had gone from 5.8-6.1 to 5.3-5.1 and they had not had more than a 2-3 quarts of water ...im running flora nova grow at around Rating: 5
