not for hydroideal is 78 root temp
+ rep ...First off, your temps are way too high, and the extremes way too far apart. I never go over 83 or under 70. Usually 72-76 for veg and 72-80 flower. You need mid 50s to 60 RH for veg and under 40 RH flower, I'm low 30s to high 20s. You really can't get too low for flower. 600w mh is way too much for 5 plants that small. I'd use 4 2' t5s @ 100w total until they get about a foot tall with the plants that close together. My recommendation is a 4 4' t5s @ 200w if you space each plant about a foot apart. Since you only have those 5 plants, I'd get a 400w CMH and blow a fan directly on the bulb, for flower. For sativa I'd need two 400w CMH. But since you are doing indica, I think one will do. My sativa get to 3 feet or more when I veg to a foot, which takes about less than three weeks veg. I just made another batch of clones today. I should keep track of the total days until a foot growth. My 4 4' t5s get a temp of 76 in the same environment. Just to give you an idea of how hot a single 400w CMH fixture is.
CMH are very cool for a HID. My temps never get over 83, usually about 5 degree increase over room temp. My res is 80. Res temps in 80s are only possible with a zyme. My roots may get a bit browner than I like, but my leaves stay bright green until flush. $10 for zyme is way cheaper than making it cooler. I personally run a Ph of 5.9 and let it drift to 6.3 before ph down. But I rarely have to. Maybe once every 2-3 days,if that, sometimes even over a week.
My next grow I'm adding silica. Aerosil is $16.50 per pound. That's enough to make 2.25 gallon solution or 1712 gallons in a res. Compare that to $78.25 for the same amount of pro-tekt.
nice post, You might be able to get away with your rez at 80 with that zyme stuff, but your water isnt nearly as airated as it would be a lower temp.First off, your temps are way too high, and the extremes way too far apart.

I have plenty of air. 4 stones and 15.6 liter of air for each 3 gallon bucket. Two 30"x30"x30" lst plants. One 400 CMH 14" from the top.nice post, You might be able to get away with your rez at 80 with that zyme stuff, but your water isnt nearly as airated as it would be a lower temp.
light/heat issues do cause these types of symptoms,not just what you have stated.idk what the closet setup is, or whats under the hood. Its uniformly taco'd, which should give clues. Light issues wouldn't be uniform, you would see burns, discoloration, and healthy leaves too. I was thinking it could be a weak seed, it looks so different from the rest. They're all getting the same food, water, and light. The only other thing I can think of right now is air circulation, maybe its in a spot that doesn't have any, and the leaves don't cool down. It just looks really thirsty. I'd mist it several times, 20 minutes apart, when the lights go off; mist the stem and dolomite too. Do that for a few days if you have nothing else to try.
The warmer tempurature might help the roots grow bigger faster too eh?I have plenty of air. 4 stones and 15.6 liter of air for each 3 gallon bucket. Two 30"x30"x30" lst plants. One 400 CMH 14" from the top.
I just did it for the hell of it. The roots are massive, 16" long and 8" wide mass. Mostly white with some brown unfortunately. 18 weeks from cutting to chop in three more days of darkness. It was s fun experiment, but I won't ever do it again like this, unless I can grow outside.The warmer tempurature might help the roots grow bigger faster too eh?
clearly you missed my point. Let me rephrase. You and your sister are sitting at your mommy's kitchen table eating the same food together. You start to wither and die. Gee, must be what you're eating? No, because sis is lovin' it. Must be your weak genes or something, right? You're just giving up on life.light/heat issues do cause these types of symptoms,not just what you have stated.
