Hey, I have a question. What do you think is wrong with the leaves in the picture? They are 4 weeks into 12/12 im giving it tap water and soiless with organic ferts per recommended schedule. Any help would be appreciative.

look right there kind looks like a mag deficiency..

Your PH is wats wrong fix t quick r youll kill em

f*cking tap water

is it mag or ph or over fert or a combo of these ?

I was using double the amount of nutes until 4th week of flowering, in soil, water from tap 3 places ph 7.0 - 7.5 then the nutes lower it a little is what i understand. Now we know to use less but i want to flush it out 1st asap. How many gallons of fresh water is needed to flush the 4 gal pot its in? The ph will be known from here on giving it 6.8. The issue(s) are over nutes. Is there more than that for sure? Because I dont know the PH so ?

buy a ph meter, it costs 30$ and check the acidity since you don't know it. Don't depend on what is written on the back of a commercial product, then start controlling the nutes. When you're flushing use molasses in the last flush.

tap water is a no go for feeding plants with,it needs to be left out for at least 24 hours if you are for all the chlorine and shite to evaporate
