need seconed opinion

hi
ive got a plant 2 weeks into flowering, soil, 400w hps
shes got purple stems and yeloowing leafs with brown spots.
the stems are still green on the last 10cm
from what ive looked its ph lockout.
my ph meter shows 6.5 but its probebly incorrect
i feed her evry second watering according to nanuf.
so should i flush her with correct ph water first or continue regular feeding & watering with correct ph water
thnks
cant upload pics. dont knew why. its not working right

Pics are always helpful. What kind of transplanting has been done through the plants life?

Seriously though, pH at 6.5 is good ─ I'd check for overwatering, overfeeding or perhaps the soil is colder than they'd like?

The discoloration and spots sound like Cal/Mag or PH problems. The redish/purple stems are common, unless it's a deep purple there's nothing to worry about!

the stems are deep purple
its not over wateringand the temp are 25-28c
ive got a right ph water and want to know if to flush her or continue with regular watering and feeding
thnks

the stems are deep purple thats my worry
ive got a leveld ph water and wanted to know if to flush her or can i continue watering and feeding as allways with the leveld water
cant upload pics. dont know why. the uploader is finishing upload and stuck doing noting.

anyone??

I'd be inclined to discontinue feeding for a fortnight to see if she'll improve . . .
But without pics it's guesswork!

Well, not nececelery ─ P deficiency can point to too low pH and purple stems signify little except perhaps low temps during the DP!
