Who are you kidding bro? The guy has one plant and a cfl and your suggestion after getting no facts besides that his ph is 6.5 is that he needs a RO system. Are you kidding me? You must work for a hydro store that sells em. GTFO dude. To the original poster, get a second opinion cause this guys a hackthat's your problem. ok here's what you can do. first using tap water or R/O water NOT distilled, water the plants. the water that comes out the bottom will tell you what the pH of your medium(soil) is. Your "runoff" water should be between 6.3-6.8 in soil to ensure optimum nutrient uptake. let me know what the pH is of your runoff and i'll see what I can say to help correct it if off.
If your run off is at six, and the water is at eight, and the soil is at 6.5, id say that all averages out to around 6.5 - 7 in the root zone dont you think? Ive seen plants grow in hydro with 8-9 ph and never had a problem like that pictures showing. Id like to know what the specs on the grow too. Nutrients and soil being the key ones. Like that dude says, i dont think its a ph problem. Ive read that chart before but seriously, the guys soils at 6.5, how much closer do you want it, and idk if it even makes sence that soils at 6.5, waters at 8, and the run off is the lowest number? You would think it would be somewhere in between right. Maybe one of your instruments is off. More info is needed id think. Good luckThe ph run off was at 6.0
