Most of the big fanleafs on my plants,they are starting to curl under.My ph is between 5.8-6.2,and my nutrients are at a CF reading of 20.Im using a flood and drain hydroponic setup,and my plants are 5 weeks old.The thing i want to know is why are they starting to curl under?. :confused:
Anyone plz????
I think overfert might cause that. Are the tips turning yellow too?
no the tips are green.
im far from an expert but isnt 20 a bit high?

No, that chap is talking about TDS total disolved solids.Its different from CF.
i read in ppm so thats all i know,hope you find the answer,gl :)
if there drooping over which i imagin them to be doing, could be not enough potassium (K) or ur overwatering?
how often do you flood each light cycle? what is the medium?
