E-indoor or outdoor - outdoor
CSL-Soil type/brand - homemade soil
SCL-Anything you have added to the soil - perlite

E-Water source - distilled water, I've used water straight from the tap a few times.
E-Source water pH - 6.5

E-Age of plant - 6 weeks
E-Type of fertilizer - see pic, I use 3 or 4 drops per 500ml 3 times a week.
the soil PH is also 6.5
There were thunderstorms last week so I think that over watering is the problem.
Thanks for the replies
