Just at a glance it kinda looks like overwatering to me. But you say your average temp is 78.. are you including night time temps and taking an average off of a digital thermo. or something? I don't know what kind of venting you have but your cabinet seems kinda small for a 600W MH, as far as heat control goes. Also you might be giving your plants a little bit too much light intensity, but thats a subject that I don't know a ton about because I use fluorescents instead of MH, but with a 600W MH I'd guess you need to keep that at least 12" above your plant, and if your cab is 3ft tall, that doesn't leave much room between your plant, the container, the light, and the hangers. That is all speculation though, maybe you're doing just fine with that lighting. I would also find a way to hang your thermometer around the top of your plant to take the temp at that level. Where you have it right now is much lower causing the temp it reads to be lower, and could also be shaded by the edge of the pot causing it to read even lower than that. So really the temp you need to know is how hot it is under the light, right at the top of your plant. One more small recommendation is that when you transplant your plants, fill the pots up a little further with soil to allow good ventilation and air flow around the soil surface. This will allow the soil to dry out better to reduce the risk of overwatering or mold/fungus/rot issues. Your plant appears to have somewhat dry soil on top in the picture so I don't think overwatering is the issue but I don't know. Just don't add soil now and bury the plant further up the stem, that will cause the main stem to rot and the plant will die.

Other than that I would recommend going to your local garden shop and getting some PH indicator dye for like $5-$10 at the most, your bottled water should be fine around 7.0 but you're going to want to keep an eye on the soil runoff PH even more than you need to check the bottled water you use.

Hopefully you can figure out the temperature thing and that helps you out. Let me know how it goes for you and post some more updates. If nothing I said helps you out then post as much additional info as you can about your plants and we'll see if we can't figure something else out. Other than the droopiness they look pretty healthy, and I'd lean towards too strong of lighting. With the trimming and transplanting it would be under stress and might not want such strong light for a few days. How long ago was the trim/transplant session anyways?
Minnesnowta Reviewed by Minnesnowta on . underarm kush week 3 veg (newbie here) Hey growers whats up. First off wanna say im a newbie to growing, and first impressions are its more complex than i anticipated. So my grow setup is, 3x3x4ft wood box built in my closet, 600 watt mh veg, and 600watt hps flower. soil is fox farm ocean forest. Thus far no nutes and been using dasani bottled water from start, i know a bit expensive, but i didn't trust my tap water. 18/6 light schedule, average temp 78, with controlled humidity around 65%. I do not check ph as i assume the bottled Rating: 5
