Your meter reads PPM & makes an 'educated guess' at what the EC is. That is why I asked what PPM scale your meter reads.... it is probably NaCl from what you say?

But which ever way, your nutrient strength is too high

Thanks for your help mate. Do you have any advice as to where to go from here? Ive had plants at this stage before with higher ppm readings with no ill effect. Id like to believe there is other growers out there that are riding this high on ppms aswell. From what ive read online it doesnt seem to me to be that high for a plant that age and at that point in flower. I read last night that having a ph above 6.0 in flower locks out molybdenum which is used for transporting nitrogen throughout the plant.

Plants are like people, they have different wants & needs... I've had plants that want only .3 above base & some that have went .9 above base, there is no hard & fast rule....

Met i gorw monsters for over 5 months sometimes with no more than 1.4 EC

Strain is listed by breeder as 56 days flowering. I have had plants yellow from top down when they are getting ready to finish.
What is the light to canopy distance?
Some strains can handle massive amounts of nutes. Perhaps pineapple-express does not like a high EC.

I asked about the lightsa also citydweller but i got no reply.

I grow 10+ zip autos at 0.65EC

Not a willy waving competition - less in this case is better!

Either way I just read the plant ... keeping as much headroom to burn as possible.
