hey all can anyone help me with this issue , i will post a pic of my nutes , im running sunshine mix #4 , coco coir .. A couple are mixed together .. The ph is always set to 6.0 .. My ppm is around 800 to 1000 .. My humidity jumped up to 70 but have the dehumidifyer in now getting it back to 50 .. the temps are around 27 c .. but i was having an issues of the temps droping at night time , but i have added a baseboard heater so it basically runs around 24 - 25 c ... i have on 24 inch fan circulating the room along with the dehumidifyer .. I use flora nova veg the 1 part solution , i have never had an issue , but is that stuff bad for toxic salt build up ? .. also the twisted leaf ls on a pure afghanie .. thanks in advance ..

hmm im no expert but any temp under 58 can cause a lock out wich starts a domino effect of issues . Have you tried a good flush with some" WARM R/O WATER" ...25cents a gallon .

Flora Nova is super salty.. I've gotten salt build up using it.. Try a nice flush & check the runoff I'm betting it's super hot coming out..

I believe from the cold night time temps a nutrient lockout has occured. The purple striping is usually saying the plants are cold. Warm up your room a bit during the night. Try to drop 10 degrees max from day to night. Also with high in salt nutrients you must feed twice then flush. Feed twice then flush. A good flush too. If you grow in 1 gallon pots then give them 2 gallons for the flush. I know its alot of work but at least give them a gallon of water if its to much work for ya. Salt build up with lock out nutrients very easily. Good luck and hope all goes well for ya :)
