Hi guys, Just a quick question. I have 2 plants in at the moment 600 w 18 hours on 6 off Ec 1.0/1.2 Ph 5.8/9 Soilless grow in clay grow rocks Both plants look healthy but i have noticed on one that the bottom leaves are slightly yellow and starting to look like nitrogen def. this is what is really getting to me. Should I be making any changes to my ph? Or should my EC be much higher? I'm using simple grow a&b and a mag and cal nutrient also along with root 79. Overall plants look healthy just in the last few days noticed a yellowing on the bottom leaves. Can anyone please help me out on what this could be? Thanks guys [emoji111]

Over the past year the FCC has come down hard on electronic ballast manufacturers. Until recently electronic ballasts received little attention.

After my clean out I'm wanting to sprout some seeds and to play it safe I want to use %50 Hydrogen peroxide to sprout them, should I just use the low dosage rate on the bottle or? I don't want to use to much and kill them.

Hello everyone, well after a case of root rot I attempted to clone everything and hope for the best that the root rot had gone, I had disinfected everything I use to grow with but the problem came back since I took clones I guess the root rot was some how passed onto them....iv binned all plants and seeds.....now I'm planning to clean everything down again before I get anymore plants going. what's my best approach to cleaning out my clone room, tools etc....will bleach kill root rot for good if I soak everything in that?

I am starting out with DWC in my first grow. I have just bought a ph and TDS meter and am at week 3. My Cyco nutrient chart says I should be at 1300 ppm at this point and ph 5.5. Ph was easy enough. Ppm started at 200 plain water and 580 with recommended nutrient levels. I added about 1/3 nutrient again and it went to 670. I don't really want to push it any further than that, ideas? Am I doing something wrong? Thanks in advance
