My tap water is around 100ppm maybe even lower. But no, it was not just water + epsom there were other nutrients added because of the flush so the 900-ish is the total.
Not that anyone watches this thread but just in case, a little follow-up. I did the flush and added the epsom salts to a solution of roughly 900ppm (ish, still can't actually measure it) And the damage has stopped progressing and everything seems to be ok. Gonna get a new EC meter this week so...
It's fine, I can translate brands and measurements to local ones XD Hardware stores and gardening supplies are closed too. It's fun times over here. Anyway, I have 2 other plants which are 2 weeks behind this one. I'm using this one to learn and hopefully not repeat the mistakes on the others...
Well we don't have those brands over here and hobby markets and pretty much anything that doesn't sell majorly food is closed because of the virus. So it's kind of awkward getting things that you don't easily find in Tesco or something xD
Anyway, gonna try tomorrow the pharmacy route
Well I don't have any epsom salts, can't go get some cuz of the shops being closed due to a lockdown and earliest delivery would be on Tuesday. So that will have to wait for a few days
Indeed, it's sort of like flying blind. What would you think about this idea: completely flush the soil and add solution of GH + calmag at 1.6 - 1.8EC (800 - 900 ppm). Obviously I can't actually measure it so I'm going by the EC values interval on the bottles.
Ton kind of reset the situation. I...
Yeah, I need to wait for my next paycheck to get a new EC meter so that will be next week. I've been using calmag with a full dose every watering that's why I wasn't suspecting Ca or Mg to be lacking.
By "eyeballing" I meant that I can't accurately measure the resulting EC of the solution or the runoff from the plant. When it comes to ratios, I'm using the GH recommended ones. With the amount to approximately hit EC of 1.6. What is Lucas formula? Also you are recommending epsom salts. That's...
