Hello All!
Doing my first hydro:
5 weeks in to flower
3 AK48 in bubble 60L res. (15.8 USGallons) cange res. every 14 days.
ph 5,5-6 (no digital meter, GHE PH liquid, ph7 from tap))
Nutes: switched from general GHE Guide to Lucas formula 14 days ago
EC: 1,2
400W HPs
Temp: day 24C/75.2F night 15C/61F
I got browns spotts on some older leafs that are spreading. And I think it´s a cal/mag problem. just want to hear from the pros. I have also found that some leafs are dry at the edges and the steam getting a red/bron color. I´m also thinking over fertilization, but it´s kind of strange the EC have never moved mush during the whole grow. And the EC have been higher (1,6). So that´s why I have lowered the nutes. Seems like the girls are living on water only?!?
So help a NooB out my friends!
Cal/Mag?
