hi again. so…first let me post details on my grow.
Strain; WW feminized from ilgm
Soil in 5gallon buckets
System type? SubCool SuperSoil
PH of runoff or solution in reservoir? 5.7pH @ runoff
What is strength of nutrient mix? TDS @ runoff = 223x10
Indoor or Outdoor: indoor
Light system, size? 1,000W HPS and 400W HPS
Temps; Day, Night 79f/68f
Humidity; Day, Night 36%-57%
Ventilation system; yes, 6" intake and exhaust.
AC, Humidifier, De-humidifier, no, no, no
So for the most part things have been going perfectly.
seeds germinated perfectly,…veg’d for 4 weeks in happy frog with light nutes, as needed.
transplanted into 5gl. buckets and filled bottom 1/3rd of bucket with “SubCool SuperSoil” and the rest with more happy frog. as per instructions.
as you can see in pics…they have been thriving, 16 days into flowering.
but the very light green had me concerned a bit, so i started asking questions. and double-checking things.
it turns out that my pH is off. despite SuperSoil creators claiming the soil would buffer and balance the pH naturally.
tested runoff today by,…watering plant with bucket-in bucket and got some startling results.
5.7pH from runoff. and TDS of 234x10.
if those readings are accurate…wouldnt i see more signs of issues? i calibrated my tester just a few days ago, so i dont think thats the problem.
tap water starts at 6.8pH and 030 ppm.
the only things worth noting is that the new growth takes a few days to get darker green,…which i believe is fairly normal.
very very slight nute burn at the tips…again, fairly normal.
growth has been on track with my expectations and havent noticed any slow down at all.
im inclined to leave “well enough alone” but those readings concern me.
