Yeah I dechlorinate my water first and by adding just A&B it seems to bring my ph right to around 5.8 - 5.9. Just switched the lights on some of my super silver and now will be adding the PK so will have to see what that does. Man those babies are over 5' tall now. Topped them to avoid stretching too much. Does anyone have prior experience growing the Super Silver at this height? How much taller will they get? Any help is appreciated.

hey lester i got this info on pk from early on in the thread think it might help you
if you got the canna boost start usin that now an wait for the pk
PK 13/14
i use it for almost 3 weeks...at 4 ml per gallon for the most part...
i start using it a few days after the flowers develop a bunch of pistols and stop when the nugs are finished linking together... by week 6 im done using it.
the plant only needs the pk for around 7-10 days, but to make sure i give it on the exact 7-10 days it is needed, i start early and end late... and canna assured me it wouldnt have any ill side effects...
i still pump it up to 6ml per gallon during the 7 days that i suspect to be the pk sweet spot.
it depends on how long your flower time is also... if you had a 12 week flower time, than you wouldnt want to use it until like week 8 or something like that.
i believe it calls for around 6ml/gal. If i added 6 ml/gal and my regular base nutes it would be some crazy 2000+ppm. What i've always done is cut my base nutes in half, water at 2ml/gal first time, 3 ml/gal 2nd time, 4.5ml/gal 3rd time.
PK tends to be best used in a 7 - 10 day window starting about the time you see first flower formation. This typically, on an 8 week flower response group, to be about 5 weeks before harvest or 2-3 weeks after flower initiation (not light change). Adding it early will not advance or benefit flower initiation, only the amount of dark the plant sees will initiation flowering. Adding too early could result in phosphate accumulation and ratio issues involving Ca and Mg
hope this helps bud good luck
