I'm using 1 tsp per 1 1/2 gallon at most waterings...once in awhile I use
straight RO or my tap water which has 180 ppm TDS. I have not experienced
any leaf tip burn... I HAVE noticed weaker flower stems this year...I dont
know if its a fert issue, light issue... the stems may be longer due to less
light...hence...weaker... I have heard this can be caused by a magnesium
deficiency, but I am no chemist (nor botanist). I was ALSO told I could use
the fert at recommended doses...I'm just afraid to do it.
As to the PPM of fert...I think the recommendation for 100PPM is a general
water quality guideline. It makes a difference what the PPM consists
of.....is it Sodium? Calcium? I'll be interested to read more on this...I'm
pretty clueless as to what strength Pleuros should get on the MSU fert.
