There seems to be a problem with my plants, first i thought of nuteburn cause the leaves where drooping also, i flushed my soil, but seemed to have made it worse... also its prefertilized soil, wich means by flushing i released a whole lot more nutes? anyways maybe the pics would help recognize the problem

temperature is around 25°C and are humidity around 50%...

what should i do?

try to foiler feed with 1/2 teaspoon epsom salt to a gal/ 3.8 L of water out the tap use warm H2o to disolve salts. It looks like magnesium dif. also since most nutes are mag shy you can use 1/4 teaspoon to gal h2o in your watering.

haha ill copy whats on the bagg: (i have to translate to english though):

fertilizer contains magnesium and calcuim.
soil with lava, grape pit, and "turf" :-D.

Dry substance: 30%
organic substance: 20%
PH (Water)Zone: 5.0-6.5
EC: 450µS/cm
combined fertilizer NPK 12-14-24 0.5kg/m³
combined organic fertilizer NPK 7-7-10 3.5kg/m³


As for water i always lower the PH to 6.2-6.5, No nutes yet, i let the top 3cm dry out till i water again.

altough i agree with the overwatering, cause i thought it was nute burn at first so i flushed the pots... it takes a while till its dry though.
