Marina Coast Water District (MCWD) : Water Quality : Central Marina and Ord Community This is the quality of my local water. Normaly when I test the water with PH strips, it doesnt show up as alkaline at all like the report says. It useually doesnt effect the PH strip at all as it would if it were neutral. Im just curious, if I aerate this water would it be fine for watering plants? Should I use RO? Im so fucking confused because EVERY time I grow I always get this yellow new growth bullshit and I cant figure out why. I dont have a PPM meter and I cant really afford any extra shit at the moment. This is what it looks like http://forum.grasscity.com/indoor-marijuana-growing/951745-what-deficiency.html I dont even know where to start honestly. My last round,I ended up letting a friend finish them. Gave him the plants at week 1 flowering(same point the plants i have now)He said what he did to fix the same problem was start using aerated tap water instead of RO water. He said he started feeding cal-mag at 1tsp with this water as well! Also he put bloom nutrients in it after I had already fed them, and it was a full dose at week 1. The thing is, I havent known him that long. And IMO it seems more like a lockout than a deficiency. The last time i watered them with 1 1/2 tsp of cal-mag + 4 tsp of botanicare bloom. The plants are still growing at the same rate it seems like.....Could he be giving me bad information because he wants me to fail as a grower? Keep in mind we buy weed from him every now and then... ugh.....I think he was telling the truth, but I just want some more people to confirm. (The plants the he grew turned out really good with no deficiencys) The 4 plants in the pic, were started in fox farms soil. Then they were vegged for 3 weeks in a pot that was too small(severe deficiencys). Then when I transfered them into the big pots that you see they are in now, they started growing alot better for about 2 weeks. Then thats when the yellow new growth started to kick in. The waterings I gave them with nutrients seemed to have little affect. The plants are growing pretty fast despite the yellow new growth however.
