Forgive me if I am being overly anxious, but my last grow was plagued with problems so I want to stay on top of things with grow #2! Here are two shots of my Northern Lights seedlings in coir. The larger one seems to have slightly yellow on the ends, larger leaves than the one that is a day...

First time growing in coir. I have read and re-read the tutorial. It says to use the first knuckle test, or feel about one inch into the mix and water when it feels dry. I also need to water until about 20 percent runoff to avoid salt build up and lock out. Problem is, I watered my seedlings...

I know this is probably a dumb question, but I have never seen it discussed. Can anyone tell me this is the right thing to do? I put cal/mag in my water. Then I add my nutrients. Then I shake them up and check my Ph. If it is too high, I put in a small amount of Ph down. Then I test the...

I have some plug-in Sharper Image under cabinet LED Stick lights. No UV rays, 120 V AC 60 Hz 79 mA Max, class 2 24VDC They are very bright. That is all the information I have on them. They aren't made anymore and my contact at Sharper Image said they don't have any information on the...

I am just starting my first coir grow in fabric pots. Nebula's tutorial on coir is great. She mentions one brand of nutes that don't require a reduction in the amount recommended by the manufacturer, I am using the above products from Botanicare. Should I reduce the strength to 1/2 or 1/4...

Just starting my second grow. This is my first attempt with coir and vermiculite mix in a 4 gallon fabric pot, under a combo of LED and CFL lighting. Northern Lights seed. I have done a lot of research and, of course, re-read everything on GWE! My last grow was in soil. My biggest...

I am thinking about using coco coir in my next effort. Does anyone know if you still use the first knuckle method to see if you need to water?

I was informed that this plant looks like it has been overwatered. I received advice on how to avoid this in the future which was great. This is my first grow and I would like to be able to recognize the symptoms in this picture. I am only familiar with the tutorial pics where the plant looks...

Hi, if I try out defoliating my plant as described in Nebula Haze's tutorial, how should I store them and can I use them to make canna butter? Recipes appreciated! Thanks!

Sorry, my first attempt at loading the picture didn't work.

I am a first timer and have had a long and painful first grow so any help is so welcome! I was getting a lot of yellow leaves but she seems to have improved with Botanicare Grow. The seed sprouted in mid February so you can imagine my frustration. More picks of the problem are on my thread...

Hi, I am not looking to diagnose a problem. I have a nitrogen deficiency in my soil grow. I added some nitrogen...10/1 water to urine. Since my yellowing lower leaves won't become green again, how can I tell if my fix is working and how long will it take? I read this can create a salt...

I haven't been able to find any information on the best way to orient CFLs. I have Ys in clamp lights which allows for two bulbs to each fixture. I have hung these around the sides of my plant as I also have an overhead LED. These CFLs are more or less parallel to the floor. I also have...

Northern Lights, Ecoscraps mixed with wood ash and lots of vermiculite, Mars 48 reflector LED, along with six 23 watt 6500 CFLs I gave her a good amount of worm castings tea that had been brewing for a few days. A few days later, this happened. ​​​​​​​

Hello, I am trying to grow my first single plant. For flowering, I will be using CFLs; 23 watt, 1600 lumen, 2700k for a bit over a total of 150 watt, 10000 lumen. For veg., can I use some LED 820 lumen, 5000k bulbs that I got at Home Depot for about a dollar each? I don't have enough to...
