I add cal-mag first and bring the ppm up to 400 before adding anything else. I never let the air temp go above 78F and CO2 locked at 1000ppm.

Shut off the light before it fries it. What is the temperature?

Nurse it back with water, nitrogen and 24 hour light . It will take at least 2 weeks to recover.

I agree more nitrogen is needed. Looks like you also have bug bites.

What is the issue? I don't see it.

My Hanna has two adjusters, one for 7.0 ph and the other for 4.0 ph When the meter is in the 4.0 buffer you set the 4.0 adjuster to 4.0 and when it is in the 7.0 you adjust the 7.0 screw so it reads 7.0 Then your meter will read right for a while. But you need to adjust it periodically to keep...

That could work by keeping the water spray off of the stem. I might try that.

I got hit hard with stem rot. I had to stop using my hydroponics system and start using all soil. The stems would turn white around the base and rot all the way through and the plants all fell over and died the last two times I used hydro. The same plants grown in soil were not affected at all...

If you are leaving them outdoors better wait until October, those are just babies.

The hairs will die back and the calyxes will grow like grapes.

You should get a 200x USB Microscope and check for 50/50 Amber Trichs to be sure. Then you can post those pics.

Could be male? Why grow males? Use Feminized seeds or clones. I will never make the mistake of growing male plants again.

Thrips are the hardest bugs to kill. Left unchecked they will consume all of your leaves. Spinosad is the answer. We have found that it kills them all with only one application. The one I use is Monterey Garden Insect Spray. I highly recommend you add it to your arsenal of bug killers.

PH Down or Phosphoric acid and citric acid.

200X Dried Weed from last harvest.

Wow I like those pics, I will post some too.

H202 works great in my hydro system. I add it every time I change the nutes out and add extra to the top reservoir. I know how much to put in and never overdo it. It keeps the valves, nozzles and pumps clog free. If I don't add it everything gets caked with bacteria and fungus. It also makes...

Have you tried Cal-Mag? One teaspoon per gallon of water. Mix with your other nutes every time .

One day can mess them up. I would leave them in the dark until the next light cycle to make sure they did not get too much light and reset the veg cycle. A friend of mine had someone watch his house when he was surfing in Mexico, his friend turned on the regular lights to water the plants and...

I have 2 300 Watt LED lights. I don't like them because they make strange lines and spots on the leaves and make them grow funky. I have never tried flowering with them since I don't want to take the risk of not having a decent crop. If you get them close they will fry the leaves but if you...
