Hope I am posting this in the right place, I asked the same question in the grow journal I just started but was hoping for a quicker reply by asking here as well. If it's not appropriate to ask this in a separate thread here, I will keep my questions confined to the journal -feel free to tell me I am doing it wrong.

Here is a link to the journal I just started explaining things: https://www.rollitup.org/grow-journals/617223-1st-time-journal-6-plants.html

Here is my basic question for those that want to skip my long winded explanation in the journal:

I have 6 seedlings in a simple diy RDWC. 3 of them are 4 days old, 3 are about 8 days old.

I am thinking it is time to start adding this Pure Blend Pro veg formula 3-2-4 but am not sure what strength. Also have Cal-mag and a "roots excelurator" and am unsure as to what strength they are ready for.

Any advice on what strength I should be adding when I drain and refill this 32 gallon system today (there's 8 of the 5 gallon buckets filled to about 4 gallons each).

Also wondering what this 4 day old lemon skunk seedling is telling me by the yellowing on the tip of the leaf (1st pic). Any ideas?

hey mate in my dwc with 1 month veg. plants on average get around 12" tall then i flip and i usually get around 8 oz per plant with a little training no topping.

i use flora nova grow and bloom with a few additives being floralicious plus, florablend, koolbloom in flower and of course silica.

my feeding schedule is based on what the plants want. i monitor the ppm in the bucket if it is going down i feed strnger if it is going up i feed less. run a flush with florakleen once a week.

if i had to right down what my feed schedule looked like it would be something like this. ( keep in mind most people are going to think this looks crazy. especially in flower when i actually drop my feed strength but thats what the plant wants so thats what the plant gets, im there bitch lol)

week1 (from seed ) 50ppm mostly just flora blend
week 2 250ppm
week 3 500ppm
week 4 1000ppm
flip 12/12
week 5 stretch 1400ppm
week 6 1400ppm
week 7 1000 ppm
week 8 800ppm
week 9 600ppm
week 10 600ppm
week 11 600ppm
week 12 400ppm
flush

keep in mind that varies a lot with different strains and im certainly not locked into that schedule if the plant tells me to go higher i will. and if the plant tells me to go lower i will. its important to flush each week though with this method as a salt bild up will give u a flase uptake reading and u could end up under feeding

So you can go w/nutes LIGHTLY after 1st set or node of leaves. Try 250 ppm or even 125 ppm then another 125 ppm a bit later if you really want to be safe. Also helps to top feed hydroton 2x/day before roots get established and show thru net pots. I use Rapid Rooters to start my seeds, work much better than rockwool. Also rockwool retains moisture a lot more than RRs so I guess focus on watering perimeter of rockwool (where roots exit) in hydroton if you use that.
