Exactly, chubbienugs!!!!!! Was going to say something but don't want to get into splitting hairs, ya know?
Cyklo...GOOGLE pH levels (water/soil) for marijuana...you'll see the same numbers coming up....for optimal results.
If using metric...a UK teaspoon Epsom salts to 1liter...have water stand overnight to evaporate chlorine. Put in spray bottle and spray twice a day until you see changes. You can water systemically every other day, but not drown. Once it looks like a healthy plant (probably 2-3 room temp applications), then continue with water. Too, you don't want to over power...diluted always easier than full strength.
Typically, I use Epsom salts about every 5 waterings (soil gardener). US measurements 1TBS per gallon...so the amount I quoted you roughly half for 1 liter.
A few applications of neem should take care of the bugger problem. Glad things are turning forward for you. Grow on!
Thanks for the quick response. I checked the pH level of the water which came out of the buttom and its around 7.0 (I have those sticky things you dipp in)
Neem oil how often should I apply it per week?
Epson salt once per day is good enough?
