Did you pre-soak your media in pH corrected solution? YES

The res is about two weeks old with 3/4th strength nutes. I changed it today with fresh RO water and full strength nutes. Is it a deficiency?

Thanks to anybody who helps

This is either a pH problem or a nute burn...

What's your pH and ppm?

i updated my description. PH is always at 6.0

Nute burn? aww crap. I thought they had used up all their nutes so i flushed and added full strength.

This may also bee light bleaching. If you keep your hand, palm up next to the top for 1 minute, does it start to feel uncomfortably hot or just mildly warm?

Welcome to RIU
flush em man got nute burn, go 1/4 strenght on the nutes, directions on nutes are for reg plants,
not sweet sweet MJ.
They will b fine damage will not get better but new growth will be just fine.

ALSO those 2700k lights are for flower not veg, get some 6500k (daylight) CFLs they will respond much better to that!

what he said

Thanks for replying guys. Im a long time reader but this is my first time posting, thanks for the welcome.

PH is at 6.0
PPM is around 1400 according the the nutes plus whatever was in the RO water.

@phenom, Im growing autoflowers and their already in flowering stage thats why the lights are 2700k.

Ever since flushing the res and adding new nutes at full strength my babies have gotten MUCH better. One of the leaves that was curled up even fixed itself!

Im starting to think it was some sort of deficiency. Im using technafloras recipe for success which consists of:

B.C. Boost
B.C. Bloom
Awesome Blossoms
Thrive Alive B1 Red
MagiCal
Sugar Daddy

Is their something else I should be adding to my res when using RO water? Thanks again guys.
