In the water analysis it says that I have 0.15 mg/L Chlorine and 37 mg/L of Chloride

I'm sorry I totaly missed ur response, by last calculation I should have 0.306 mS/cm (150ppm)

I've read that in veg state plant needs around 300ppm and even more as it flowers, but on some other sites I read that 150ppm is considered hard water and anything above is very hard water. So what does this indicate? Do I need "very hard" water?

Currently I have the ph drops tester from GHE and also use their ph down. It came free along with the nutrients. The digitalph meter will come with the ec/ppm meter in a kit that I ordered today. If I use online converter I get 306 microsiemens/centimeter (μS/cm, uS/cm) = 0.306...

I cant upvote any comments or give any "stars" but thanks everybody for all the information and time

I just ordered digital tester for ec/ppm so I can have more accurate readings of the water that I'm using. I check ph daily, water temps are quite low. I also removed any other heat sources from the box that would cause the water temp to go up. I must say besides those leaves, roots seem to be...

I'm not very familiar with these measurements, they are European so they probably differ from US measurements. I tried using converter but I rather posted the original EU measurements because I got confused with values when converting and it seemed I could cause more problems then anything else...

I think that he is refering to white powderly mildew (mold) but I could be wrong

I just took the 2 leaves off, I dont know why but I feel so bad about it, hope she recovers. I will give update every few days

This is exactly what I did today, I mixed 800ml of distilled with 1600ml of tap water. If I dont see any difference I will probably switch to distilled and add cal/mag myself. I smoke about 15-20g per month, I think that I could pull it off in the case for my needs. Im not hiding it from...

Hi friend, I think the reason no one is replying is that you gave too little information. Is it indoor, outdoor, which light, which substrate, which nutes, water readings etc. Without those things I dont think that anyone can give you accurate reason for the state of the plant

Many suggest switching to distilled and adding Cal/mag, what do you think? Would mixing tap with distilled water help?

Thats what I was thinking of doing, should I add anything else to distilled water besides Cal/mag and GHE flora series nutes? Will mixing tap water and distilled water make any difference? The reason for growing in such a small space, altough legal where I am, I dont want everyone that comes...

Oh my bad, I read somewhere that its corelated. So it would still be ok to add Cal/mag with those water analysis readings? @hotrodharley thats correct EC at 20 degrees its not .306 but 306 μS/cm. Here we have a lot of limestone therefore we should have quite hard water.

the EC is 306 μS/cm, PH is 7.7, water should be hard which is indicated by the ph @lime73 today was the third water change, 2 of those were 2.4l of tap water. I was concerned that the high magnesium in water is not allowing the plant to absorb calcium properly so in todays third water change I...

Hi all, I'm having some problems with auto blueberry f1. I cannot identify what exactly is wrong looking at pictures and descriptions so if you could, any help is much appreciated. Specs: Very big PC case for growing (insulated with diamond diffusion mylar) Vetilation 120mm outtake and 80mm...
