Just to let you guys know, I posted this in the organics section too. I really need some help!
[FONT=Arial, Helvetica, sans-serif][/FONT]Does anyone have experience with Plagron's Bat Mix? http://www.plagron.nl/Index_uk.htm I transplanted my 9 plants into this soil about 2 weeks before
12/12 lighting. It's low in Nit. so it should be perfect for blooming. It's also fairly hot otherwise with Bat guano and worm compost as some of their main
nutes. I had a lot of problems during veg. with low ph in my soil mix which was peat heavy, and had a nute lockout. That's why i switched soils. Now after about 3 weeks with this soil, the ph has gone up from 6.7 to 7.3 and the only thing i'm adding is water. My tap water is between 7.9 and 8.3 so i'm using
vinegar to bring it down. but obviously not enough. My plants are getting a lot of yellow leaves starting at the bottom and working up to the middle and a few near the top. some have brown dots, but most just yellow starting at the tips and edges. I foliar fed with Nit. twice and once wit epsom salts in the last 2 weeks with not a lot of change.
My setup is 600 watt dual spectrum bulb one extractor fan 187m3/hr or 110 cfm, and 2-6 in. desk fans. Humidity and temps are in good range.
I think that i just need to bring down the ph, but i'm not sure if that's enough or how to do that safely and quickly.
I've heard that in organics ph is not that important, but something is really wrong here. These yellow leaves really freak me out.
I would appreciate any help with this problem. Thanks in advance.
