Why now? under 2 weeks til crop

I give up ive spent 3 weeks trying everything to figure out what was happening take a look.

photo were taken in regular light
hydro/aero
room temp 68-77
looked for mites,attempted to treat nutrient lockout,h202

whats your ph of the water youve been using lately?

Looks to be the later stages of Potassium deficiency. Have you tried flushing your plant, after that try adding Cal-Mag to your watering schedule?

i reckon it could be over fert or the ph is wrong,too low or high

ph is 5.7 .

go to Marijuana Plant Abuse

No at this point just flush with Clearex or what ever you would like. But I'm pretty sure it was Potassium deficiency. Next time at the first signs try Cal-Mag.
