Hey y'all i still have a problem with a couple of my plants, take a look at the pics i think its ozone damage or cal/mag deficiency also the ones that have the problem are very close to my fan can this cause the problem??, i heard that generators or fans can cause damage to the plants that are closest to fans generators ??
I had a similar problem with my ladies when I started using filtered water. Turned out mine was a Ca deficiency. Throw some Cal/Mag in or stop do a 50/50 mix of RO and tap water.
Hope you get it sorted - doesnt look too bad....yet!
I used to use distilled water when they were younger but now i just use tap water which in my area is between 6.8.7.2 pH im new to the grow scene this is my first grow, what do you mean SeenTheLight when you say 50/50 mix of RO and tap water??
mine will get like that when I have filter prob and or cal mag issues. I mean my ro filters were bad and that I was adding cal mag to a soil that was heavily amended with bone and other dry ingreds so it is fine on it's own. I stopped and changed filters and no more cal mag and I am fine.
A lot of people have asked me the same Q Rootbound the ph of the feed water is 7.0 and the run off is a measley 3.3 my soil is too acidic i think or their is alot of toxic salt build-up??
I am not a dirt farmer .If I had those numbers my plants would look like a 3 day party in Hussongs. Do you realize there is a big gap between 3 and 6.5 pH? Is your pen calibrated? Do you have an ozone gen in your room? JK
if it is for lawn and gardens yes it will work just fine start with 1 teaspoon per gal of medium i.e 1 gal pot 1 teaspoon its kinda hard to put to much flush them good and test run off i would flush get a good run off test it if not good let them sit a bit and flush again test run off and see were its at run off should be around 6.3-6.8 6.5 is ideal 3 something is off the charts low dont know hoe they are getting any nutes with that ph once you got the run off where you want it water with a mild nute mix hope this helps i am sure someone will be able to help you get it straight good luck and keep us posted
