I guess recovery depends on damage/lockout (how long the ph was out ect) ... if roots are growing & there no worse then give it a while & just keep monitoring the PH/EC .... If the PH is good she can feed & recover ..they look ready for 5.7-5.8 range as well TD.
im getting PH dropping right now as the ppm are a bit high & slowly rising . Just made a fresh res to bring it down 50 ppm & should be good now (I hope) ...also had cal/mg deff come on quickly & bad (main reason for res change).,..so I upped the cal/mg 5ml from the last amount & hope thats good too .I'll be checking every few hours to make sure stuff is in check & gauge if shes happy ,you get the idea !:smokebuds:
