Thank you for the input. I was holding off from putting more notes into as it's easier to add than to take away. I wanted some other folks' opinions first before I altered anything. Its spring water with a ppm level of about 10 before nutes.

My indoor grow room is in about 64 degree temperature, and I'm unsure of the humidity. I'm around week 4ish. It is in DWC ppm level is about 312, and the ph is around 6.15. I'm using general hydroponics. This is under a 450 watt vioarspectra led. I thought at first maybe light burn, so I moved...

Is this a reliable drug test, and is it negative?

I thought light leakage was the only thing that would caus3 weird growth like this. That's why it was the only real thing I checked before asking here. I could be wrong, but I'm almost certain I've eliminated the chances of light leakage. I hope it is excess nitrogen because I cut way back on...

The nitrogen could be the culprit. I'll dile it back next time I add nutes. Otherwise, it could be the outside temperature being too high. I have a 450 Watt LED, and it doesn't let off much heat.

I forgot heat stress could do this too, but the 450 watt LED viparspectra is about a foot and a half away, but the light's don't harldy let off heat. It may be the temperature outside being too high. I live in Tx and it's 70-95 depending on the day. The tent isn't sitting in the sun though, so...

What's this new growth on top of this cola? It looks like it's going back to veg on this secondary cola, but there is absolutely no way their is light leakage. For one, it's a sealed grow tent, and two, I have the light cycle go off at night.

I am not home at the moment, so I am not sure the exact amounts, It was pretty hot at one point. I had it up to 850ppm, and that was when the nute burn occured. I diled it back to 500 to 600, and that I am not doing it per gallon. I am doing that concoction for the entire 3 gallons.

It is general hydroponics trio, and at this point, I am doing a 1,2,3 ratio. About 7.35 ml flora micro, 14.7 ml flora gro, and 22.14 ml flora bloom. I use ph up and down from them too. Right now it is at about 5.9 ph, and 600ppm in 3 gallon reservoir with a 450 watt led main light and 2 100 watt...

I recently had a nutrient burn problem, which I addressed by switching reservoirs and lowering nutrient ppms from 700ish down to about 500. My plant leaves seem to be yellowing. I noticed this morning that somehow the ph had dropped to about 4.1! So I brought it back up to the regular 5.5-6.3...

Hey guys. I'm 7 1/2 weeks into flowering with this pure landrace sativa Durban Poison, and I'm wondering if anyone might be able to tell how much more time this plant may need. It's under a 450 watt LED grow light, with two 100 watt supplemental lights. It's being grown hydroponically.

Durban Poison about 4 1/2 weeks into flower. The leaf edges seem to be turning a bit brown.

Hey my plant is very sativa dominant. It's durban poison. I'm in the second week of flower, and I was just wondering about how much longer it will be stretching for.

Nice, since I added more nutes.

I'm growing this Durban Poison sativa in a 5 gallon bucket with 3 gallons of water. I'm using distilled water with general hydroponics nutrients. I'm putting 1 1/4 tsp of hydro bloom, gro, and micro into the solution. The ppm is 300, and the PH is 5.7. I'm using a 450 watt led vipar spectra...

I'll have to pick one up. Thanks for the help!

That could be the problem because I'm using tap water.

I think they are healthy. They are just beginning to get through the net pot.

I'm measuring PH at about 5.7 and I used PH Down, but did not check ppm. Im not sure exactly what ppm is though.
