bangi haze momma been doing this all her life... new growth is perfect then old fans get burnt up like this and eventually fall off. all clones from this plant have also developed this problem and they are in hydro... they looked good as they rooted and grew but now on 4-5th new nodes they are starting to get burnt like this as well.... while i have Bigbud plants in the same hydro setup that are perfectly healthy.

whats yoyur ph???

ph is always 6.5-6.8 when watered in soil and the hydro one is 5.6-5.8

up up up up up up up

Your hydro one might need to have a slight bump to its ph..try adding a tiny bit of Baking Soda to your mix unless you prefer using actual PH UP and PH DOWN.
