Hello Everyone, this is end of week 3 in flower. Some bottom leaves are partially yellowing - in what seems to be a K def? which doesnt make much sense cus I feed 20-10-20 650ppm on average with low 6 ph (soilless)- with added silica and ph down ( P ).
maybe Ma def?
Would really appreciate any input
I also amend the medium with gypsum, I sprinkled a little more when going into flower… but nothing that would cause a toxicity as far as i understand.
My journal is here
but I can summarize
Medium:
45% PEAT
45% VERMICULITE
10% PERLITE
- Added
Dolomitic Lime at 40g per 28.3L of medium and
Gypsum at 10g per 28.3L of medium (I have added about 15 grams per 28 liters)
Nutrient: I try to water when container is light
1.2 - 1.3 EC (600-670ppm) 20-10-20 Peter’s
Tap Water - 120ppm
- Added
light dose Armor SI 2 ml per 10 L - start 2 weeks after sow.
PH
low 6
VPD:
has been maintained at about 1 to 1.2 with minor peaks out of that range.
