Hi Nectar Fam! Very first time growing and so far my plants seem to be doing ok. I'm using the NFTG sample pack. But after watching all the OCGFAM vids, reading thru the bible a few times (v5.0 would love to ask for v5.2 from someone on here), and going thru this entire thread twice now, I can't seem to get my slurries in line.
Please help, I want to get my numbers in line before I flip to flower. No matter what I do I can't seem to get the soil PH into the 6's and ppms above 200.
-Day 38 in Veg
-Light: Black Dog Phytomax 2 600watt LED (18/6)
-Room temp is 82 degrees 55%-60% RH
-Soil is Roots Organic 707
-5 Gallon Fabric pots
-Slurry #'s: All my plants test between PH 7.5-7.7 and between 130ppm-180ppm tested in distilled water the morning after feedings
-Meter: Hanna Meter (700 scale)
Have done a few flushes after every 3 feedings, 2 TBSP HH flushes and/ or 2 TBSP Gaia Mania flushes PH'd at 5.8-6.0. I PH all my feeds at 6.0. Based on what I've researched, I believe my issue is the extremely hard water here and build up of calcium bicarbonate, but I don't know how to correct it.
Tap water: 350ppm PH 10.2
Water out my RO filter: 006ppm PH 9.2
I followed the sample regimen to T for first 25 days of veg, but kept seeing a Mag Deficiency. Ever since I bumped up the Demeter's (gradually 2x, 3x, now 5x), leaves are nice and dark again (attached pic of what the Mag Def looked like). Should I back off the DD, or do you believe the high PH is why Mag has a tough time getting up?
Current Feed:
2tsp Medusa
2tsp Gaia Mania
2tsp Athenas Aminas
5tsp Demeter's Destiny
9Tsp Herculean Harvest
1tsp Zeus Juice
3tsp Hades Down
1/2tsp SLF 100
PH 6.0 1200ppm
Please advise!
