when should i start giving nutrients

When should I start giving my seedlings nutrients they are 3 days old and was thinking about starting 1\4 strength in a couple weeks I don't want to start to early and kill them any help thanks

Soil? Hydro?

Hydro

Duh, as in bubbleponics, sorry. If growing is new for you, Id pick a up a basic 2-3part nutrient set and use their feel schedule as a baseline. With that being said, Nut companies tend to say over feed on their instructions so you buy more, more often. When growing becomes more familiar to you, you be able to adjust accordingly.

Typically, I would start nuts 6-12in, based mostly on growth.

A couple are about two inches now will they be ok with only water until 6 to 12 in. And if you have any other info for me about my set up I'm all ears been studying trying to learn the ropes but it's hard to find reliable information I'm growing bag seeds now to practice but once I get it down I have blueberry kush and a citral strand

Do you have a ppm/ec meter? That will help quite a bit, at least then you can take notes and say by this week i want to be at 200ppm, next week 300ppm and so on. Although keep in mind different strains want more or less than others so you gotta find the right balance for each but as you creep up you can find the level it wants. I starved my first plant by accident(not to death) and went crazy trying to figure out what was wrong but then i bought a ppm meter and realized i wasn't giving enough nutes.

Feed schedules and what to start at and what to max at are kind of a controversial thing as everything is, everyone likes to do something differently and everyones way is the right way.

I personally start with about 100ppm for the first week and work up to 400ppm by week 3 or 4 and then probably around 100ppm up per week while vegging, then with flower i get to around 900-1100ppm finding the max balance. I basically followed the gh flora series bottle label by a 1/3 or so of their measurements. The plant will tell you if it's getting too much or not and the ppm dropping or rising will tell you as well.

Just gotta find what works for you, a good starting point is running 1/3 of bottle recommended and working your way up

Feed day one. 1/8th strength or 0.2-0.4EC

Your plant will look like shit if you dont feed until they are 6-12in

Another factor is; well, tap, or RO water?
My city's water runs at 0.4 EC (200 ppm Hanna) as a baseline.

Not using Nut sets, I add only as the plant shows signs of deficiencies.

Every garden is different..

Well you dont know what makes up the city water so I was always under the impression either use RO water or disregard the baseline reading if your water is that high. I realize here in the northeast we are spoiled with low ppm water. My water is 90ppm (.18EC) and I consider that high for the area. Where I was living I had (.12EC) water that was 6.7pH. Was awesome. I miss that water.

When I said 0.2-0.4EC I meant of nutrients.

What is RO water?

These are my plants and my set up do they look normal a couple look strong to me and a few look really weak any info

These are 3 days old

I would (and do) start feeding full strength (1.0-1.4 EC)

Yeah...I always hear you say that. How do you run so high so early? I've fed that to plants 1ft+ and got signs of overferting.

I can't understand why you'd have signs of overfeeding at 1.0-1.4.
