Nutes for autos; when and how much?

Hi guys, just started my first grow ever and went with some auto speed bud. They sprouted yesterday (day 5 from germ) and was wondering if I should give them a light dose of rhizotonic? If not, then when? I know it's easy to burn autos but I dunno if rhizotonic is safe to add now? I wasn't planning on feeding anything else til like day 20 or so. Thoughts anybody? I wanna make these little beauties the best they can be!

Hold on to adding nutes yet. At this point it's very easy to kill be it auto or regular... The water and soil should carry it for now... When I'm cloning plants - the cuts do fine with ph corrrect "plain" water that is only changed every 7 days...

if in soil, i'll start nutes when the first set of leaves start to turn bit yellowish.. rhizo should give 'em some edge on root developement, thou.. start at 1/2 dose if even that..

Ok, i thought rhizotonic fell under a different category than other nutes maybe, as i read that some people use it to germinate with even. Is there anything i can give now to strengthen these young autos? (Other than ph'd water). Thanks for the speedy replies folks!

I soak my seeds in 200 ppm, never had a problem. Went up to 300 on some strains.

Some autos can handle massive doses of nutes while others die from next to nothing.

A lot of the big names breeders have built up their strains to take over 1000ppm

You can research your strain and medium to see what others have done

it's speed bud auto, which is pretty new so there's not much info in regards to tried and tested kinda stuff, found one journal but wasnt too useful in terms of nutes. (can't post the link cos I don't have enough street-cred in here ) I'd love to start a journal but i'm waiting for the images upload issue to be fixed.
