Sounds like what im going through first time soil and started having all the symptoms you are saying. I gave mine ro water every time its thirsty and seems to be slowly coming back!
Home grown strain Kronic kush you got to be sitting down when taking a hit guaranteed to make you black out even had wimps say it was laced pure Kronic kush!!!
Well my girls are looking alot better after flora kleen, just connected my inline and carbon brought my temp down to 70.0 Fahrenheit ++...oh about my ppm meter .5 .7 is that the accuracy your asking about?
My ppm is 1300 & 5.6 ph and i dont have cal-mag. I thought it could maybe be nute lock out so im flushing plants for 1 hr with flora kleen then same nutes but -root innoculant & bacteria....and also do a foilar feed with spray n grow + flora vegan.
got three girls on 12/12 having minor problems can not identify the problem!
Chocolope
Kalashinova
Kush Berry Cronic

All new nute changes are ph'd at 5.6 as ph goes up after a few days all General...
