Hey, so my plant is two weeks old and going strong. I seem to have watering dialed in. My question is when should I start feeding nutrients to the plant? I’m using a well amended soil.
INGREDIENTS: Organic ingredients including bat guano, premium earthworm castings, fish bone meal, feather meal, green sand, mycorrhizae, glacial rock dust, soybean meal, humic acid
I understand that the plant can coast for a while on what’s in the soil, but when is it time to supplement?
The plant has been grown from seed in a 4.5 gal pot full of this soil

Post a picture so we can see what you are working with
From the sounds of it you should be good until flowering as long as you dont see any signs of an issue

Sorry it’s kind of hard to see the plant, I’m using the cheap LED that came with the tent until I can afford something nicer, but it’ll have to do for my first grow. Two week old plant, perky and green. I give it 1 cup of water every 3 days or so. I keep a bathroom scale by the tent and wait for the pot to get back down to dry weight. No drooping or yellowing. Literally gets noticeably bigger every day, really exciting.

Was the soil pre-amended with these organic nutrients and is that your intent to continue with the organics? The most accurate method to checking the available nutrients in the medium is a soil slurry test, I run a slurry test from a soil sample straight from the bag so I have a starting point

Bet… maybe I’m in the wrong place, but I won’t high jack the topic. I take my business elsewhere. Much love.

Good advice man! And OG definitely meant no ill feelings about the language thing. Mods and powers that be aren’t a fan and every now and then start handin out flags. Think it’d be cool to stick around growmie!

Maybe you’re right, there’s other forums out there that allow this

Doing a slurry test is actually really good advice
Then monitor your run off you will see the PPM drop over time and know when you need to add Nutes
Your plant looking good so far
Watch your plant for stretching if it dies start lower your light most leds MFGs recommend 18-24 inches away from plants top and that is a good starting point you can always raise or lower it as needed

Can you explain exactly your process for this slurry test? I would be very interested in trying it. I have a TDS meter that measures ppm
Yes, the soil was pre amended. However the fertilizer products I bought are concentrated synthetic forms of nitrogen, phosphorus, potassium and a bottle of CalMag plus. I’m not interested in being purely organic or synthetic for any dogmatic reason. I like that I can measure the synthetic salts into a very precise formula based on ppm
