really? 5.5? that seems a little low for coco. i was told to treat coco as a hydro set up. and with hydro i was told you want around 6.0

maybe is im using a small nft just now and keep it at 5.8 and e.c about 1.2 but think i will increase as plant gets older
oh and by the way its my first hydro grow

You are correct oH, its almost impossible to overwater in straight coco. And your issue looks like a typical R/O issue. Your plants are deficient of both calcium and magnesium....which if left unchecked will lead to other deficiencies...

YUP! i am. but i think my major fuck up was the not having a ph meter the first 7 weeks. i started them on a feeding schedule a little late as well. i have many issues i am dealing with, it is not cool. but i have 3 wonderful looking plants that i hope 1 will at least be a mother, and the other 2 i can yield something off of. plus i really like this strain.

i am using Botanicare's Cal/Mag...rather religiously. but im just now getting the ph locked in, so i think it may because of that?
