Runoff EC & PPM Question

[Cannabiskollektivet]

Hey AFN,

I'm on day 29 and my babies just entered pre-flower. Gave them a good feed with full nutes and the EC was around 1,2 and the PPM around 900-950 ish. When i measured the runoff tho I got really scared, the EC levels were around 4,5 - 5 and PPM was around 2300!! Did I just overfeed the living shit out of my babies?!

Whats the next step? Wait 2-3 days until dry and then flush with 30L of water? They are in 15L Autpots right now, with the autowatering function turned off.

Please I need your advise. @Mañ'O'Green

Thanks in advance!

Its worth adding that i'm using Biobizz All-Mix wich has alot of premixed nutrients in it, can it be that the runoff has the excess nutrients from the soil in it? I have always used nutes at half strenght, the feed I gave them today was the first full strength one.

Autos do not need more than 500 PPM. I do not use run-off PPM but that does seem high.
