You say the light is too close? Will that harm the plants? They don't seem to be burning or anything.

Yeah the soil is MG and it burned the lower leaves on a couple of plants. I haven't fertilized at all. Knowing the soil has it in it. So hoping the plants can get larger so they will be less likely to get burned. I had a thread on the issue a couple of days ago in the help section...

More like under watering them honestly. I let the soil dry very well before watering I have a soil moisture meter I used. I just watered them about 30 mins before that picture. The ambient temps and canopy temps are 79-82 so I don't think there's a heat issue. Late in the evening for me so...

Planted on 8/25/2016 germinated and sprouted on 8/30/2016 So these plants are about 18 days old. The pots are 6" pots for reference.

Looks like a male to me.

They have a lot of lights. Like their entire house is a giant grow. The biggest thing is the tent keeps temps down by having air circulating. Dont know what to tell you buddy. They are mainly looking for warehouses with hot spots I bet. Not peoples houses or apartments LOL.

Hard to say but I can say that you can hold your hand on the glass and it wont burn you or be very hot with a good inline fan running the exhaust wont be very different from your ambient temps.

The exhaust air temp? Not that hot. Maybe a couple degrees above your ambient temp.

I'd like to first start out with this is my first cannabis grow. I have always been intrigued by a plant that has so much stigma around it. How can growing a plant that grows naturally from the ground be so illegal? I am a huge plant lover! Vegetables, peppers, fruit, anything beautiful and...

Yeah as stated before too early to tell.

Doesnt look like cannabis LOL.

LMFAO. What in the hell.

Your bottom leaves look exactly like mine started to look on my seedlings. What soil are you using? Miracle Grow?

Bump? Any one else have an opinion?

The grow tent temperature range stats basically a constant 78-80 degrees and at night going down to maybe 70. But I don't really understand the canopy temperature and how to control that other than adjusting the distance of the light. I set it at 18". I am running the lights on a 18/6 cycle.

Then by your method of measuring my light is only 14" above the tops of my plants. I am assuming that is too close. Didnt realize a couple inches had so much impact. I will raise the light to 18" and take my canopy temps again. Information on my setup. Its a 8" xtrasun 84 hood with an open...

Placed thermometer at level with top of pots and it read 90 degrees. I am surprised to see that. What are acceptable canopy temps? Do I measure my light distance from the glass? It is air cooled. Or the actual bulb/reflector behind the glass?

This is a 2 week old Jack Herrer plant that I have grown from seed. It has been growing very well and looked amazingly healthy until this morning. I check on my plants and the biggest ones have this weird leaf issue I have researched and have no idea what it could be. And want to correct the...
