    water on leaves is either the leaves are touching each other all the time in the spot and all perspiration from the leaf it trapped and/or the humidity is WAY to high and the water hasnt got anywhere to go

    From the color of the plant that your having problems with is do to nitrogen deficiency, (over watering) or lack of potassium. When your watering coco you dont want to make path ways for the water since water travels in the least path of resistance. Basically if your watering on only one side it probably has pokets where water travels and not getting all your roots saturated. Also you may wanna put a low power fan on the bottom to circulate the air. This will prevent that middle plant with the issues. Omce it starts really flowering you will have major issues (Mold growth) . It all dependes on the climate but with that light and that much foliage you may wanna get a exhaust fan and let fresh air come in. Maybe a dehew needed week 3 or 4 of flower. And them m f is gonna stretch while growing. Yeee tight spot less is more i would do 4 plants in a 4×4 some time 3 on scrogg and you can get full canopy coverage. But looks good Keep up the great work.

    I tried tap water.leaving it out for 24 hours before use,I had minor problems in late veg,then right around week 4 of flower,the problems really started .Some people are super lucky and have a low mineral count at around 100-150ppm(soft water)out of the tap .I finally tested my water and it came out at 330 ppm(hard water),hence,the problems.So it really depends how hard, or soft,your water is.With hard water,the molecules are too big for the roots and start clogging them which results in inefficient uptake of nutrients.or even complete lock out .With soft water,100 ppm or lower,you need to add cal mag.I now use R O water at 0 ppm and then add my own cal-mag until I get to around 150 ppm.My plants have never looked healthier.

    The deep green leaves hint at magnesium deficiency.

    Filtering your water in coco and other hydro uncomplicates things, as long as you add the lost calcium and magnesium back in. Usually tapwater has a persistenly high pH because of too much calcium. There are also heavy metals, chlorene, etc. Plus the content/pH may fluctuate relative to the time of year.

    Okay, your using an iPower ballast. I wondered on your other video.. I've wondered how an iPower ballast would do with a 945W/1000W CMH-DE lamp, and whether they'd be compatible. Some ballasts will blow out the CMH lamps, but it sounds like yours is doing well(at 600w, at least). I know the lamps last much longer with the low frequency square wave technology, but if you get a year out of the lamp, that's acceptable. I subscribed to your channel as your using much the same setup. Blue Planet Nutrients as well, lol. Are you using the Farmers Pride base nutrients, or the 3 part? Thanks for your time, and the video!
