Flush because nute burn

[Scott grower]

Hi All

So I'm having to flush my 3 week old babies as they seem to have nute burn started on the second set of single leaves but now looks like it's just affecting the above 3 leaved stalk.

My question is... is there a possibility of overwatering during this flush and should I just use normal ph'd water?

Any advice would be really appreciated.

Thanks

You shouldn't even be feeding 3 week plants, especially if they're in a soil similar to ocean forest or the like. Personally I might feed them something like seaweed extract, I used to use just this and rely on whatever microbes I had in my mix but now I plan to use a compost tea like heisenbergs with a dose of beneficial bacteria and maybe mix in 5ish ml/g of a weak organic base nutrient like 1-.8-.7 or something. But I would also probably wait until probably my second node to add the nutrients. The tea could be added around the same time you get your first true leaves in a very small amount. Then I would probably just mist to water until the soil was dry.

The flush will overwater them at that point unless they're in tiny amounts of medium. In a solo cup you might be ok but a 1gallon will be too big for it to drink quickly.

Ah ok. I'm growing in coco so only enough nutrients for the first couple of weeks. Then I used plant magic coco a and b and root stimulant.

Thanks for all info! I did the flush today and got the water down to around 200 ppm.

Oops didn't know you were in coco, those were mostly soil answers, in coco I'd still probably wait until I saw a deficiency to feed the first time, or is start at like 1/4 or even 1/8 the dose if it's still in early veg like that. The compost tea is still probably a good idea though, it should cut down on veg time if properly brewed with the right bennies.

Also I have no experience with coco personally but I don't think flushing will overwater them to the point of damage. Also not sure on how organics work in coco so whatever base you're using watered down might be better.
