hi everyone i kinda have the same problem
my plants are about three weeks old and i use the hydro method
my ph is 5.8 and ppm is 700
this problem occured when i was using the dutch master formula calculator
i followed the measurements for my crops but didnt realize it was the totaled mixtures for the plants
i was using just grow gold A & B and the ppm was 900 i notice a day later my leaves started to burn
i tried to flush with it didnt do nothing my plants seems worser
can anyone help out please

bio terra plus is a very rich organic soil....... u might wanna not use too much ferts in it until flowering.... i think its a ph problem along with too much Nitrogen......
Good luck
peace out

Flush the plants through it may be a salt or onother build up from the feed,flush the plants and i'm sure that they will pick up.look for a new feed with a high n.p.k.take all the yellow leaves off this may make the plant look bare but they are no use to the plant anymore.and see if all the new growth goes the same i would let dry then rewater has well this could be a root rot issue if you have bombarded the plant with water.
