April 12 Day 23
Watered with 2 g (1 tsp) of barley sprouts dissolved in 1 L of water. This increased water TDS from 134 ppm to 190 ppm. Barley sprouts have a high nitrogen content (13-15%) so this might represent about 10 mg/L N dissolved in water.
LAB are lactic acid bacteria, and these are being used at 1:250 dilution as a spray on plant and soil surface.
April 13: first day in greenhouse for WP1. Warm enough to have in greenhouse for the afternoon.
April 14: another nice day in greenhouse. Applied barley sprouts again and sprayed LAB on plant and soil at lights out. Plants have perked up after transplanting and look appropriately green so they’re likely getting enough N from the barley sprouts.
April 15: more afternoon sun and applied first barley SST.
April 17: LAB dilution changed to 1:100 and sprayed on leaves and soil at lights out.
@Ferenc, thanks. I like these Wonder Pies for outdoor, and one last year was very beautifully coloured so I’m looking forward to seeing that again. Cheers.
@SegaYGriega, for a beautiful plant you should check out my Desconocida Kush diary. And my Zkittlez OG looks really good too. One advantage of growing outdoors in a climate with cool nights is the great colours you get.
Thanks @Northern_Ent, there is a story behind that. Due to the fact that I am quite energetic, I have military service behind me, so I approach problems in a quite original and direct way. For example, at work, I like to ask uncomfortable questions to managers and deal with them, that is in place where the problems arise. It caused my colleagues at work to start calling me the "Crazy Horse" . Finally even the deputy manager started calling me like that 😎😇💪
"April 26: yellowing (chlorosis) indicates magnesium deficiency. This is due to a combination of cold temps and high sodium content in the water here. This creates a high SAR (sodium adsorption ratio) so this water needs to be re-balanced by exchanging Na for Ca/Mg."
You maybe got a little bit of chloramine and fluorine in water? I mean there are a lot of possible issues, so I'm just speculating.
First thing though, the cover there might create lighting hotspots at places, I can understand why you use it, just saying though..
I would definitely recommend mulch or such (basically just deeper roots. more heat).
Maybe some carbs/sugars and phosphorus (that shit is gold in cold, cellular energy).
Oh right, and if it's cold if air humidity is low or you're in a dry area/season, definitely some extra water (mostly for heat).
Cheers and good luck dude.
@sir_isO, hey I got some lab results showing my water hardener wasn’t as effective as I had hoped. Now using feed grade limestone dissolving in vinegar to make a calcium acetate solution that is then added to the irrigation water. Works great and plants don’t seem to have excess sodium issues any more.
I still get holes in some of the young leaves when the plant is vegging fast. I’ve been upping the calcium in the water but it still seems to be happening (gumberry GDP for example). I thought yellow new growth indicated lack of magnesium but I saw something the other day saying Mg deficiency is a long term problem and wouldn’t develop that quickly. So I guess that means I’m shorting on N which has been apparent for a while now. Any other explanations? I’m pretty sure it’s not a pest but it could be.
@Northern_Ent,
The metals and contaminants to be concerned about would typically depend on the source of the lime....fluorine might be present, sometimes even shit like boron might be excessive.
But yeah, the feed grade lime (it's crushed limestone) I mention is also CaCO3 mainly (the rest mostly magnesium and sulphur). Yes, horses eat that. Also, it'actually a decent alternative for bulk calmag sort of supplementation (as in, if I need calmag, myself).
@sir_isO, limestone (CaCO3) is not lime (Ca(OH)2) or quicklime (CaO). Normally it would be pretty inert for cation exchange but I ‘activate’ it with vinegar first to release CO2 leaving exchangeable calcium.
It’s not feed grade lime but rather crushed limestone that is sold as bedding material for paving stones. What metals would you be concerned about? I could switch out this limestone easy enough and I hadn’t considered the metals risk.
