Update: Adding epsom salts seemed to stop the damage. I clipped off the twisted tips to see if any new ones came about, but none have since I've started supplementing my water with epsom salt. Lesson for my next grow: Because I was using hard tap water, I suffered a magnesium deficiency which...

This sounds like it could be a magnesium deficiency -- I just dealt with this problem myself Help! leaves turning white/pale on edges and curling upwards. Does your plant look like mine did? The leaves were turning upwards and the green color was disappearing from the leaves. Are you using...

Thanks Ganjahorder. My CFLs were about three inches from the plants. But I don't think it's heat stress for the following reasons: 1) My CFLs don't get that hot 2) I have a thermometer at the top of the canopy, which holds steady around 75-80 3) the leaf damage is not correlated with...

Update: I think I might be dealing with a magnesium deficiency, probably because the tap water I've been using is hard (>200ppm). So today I added 2 tsp of epsom salts (dissolved in a small pot of water) to my res, which was holding 8g of nute solution at the time (1/4 tsp / gallon).

Hi Everyone, I'm a first-time grower who has run into his first problem, about sixteen days into the 12/12 flowering stage. Things were going well with my grow, but certain leaves, at different parts of the plant, are now turning a pale, white, or tan color, and the affected leaves are...

Re: Smell. Or...Help me convince HER,lol! I would also be interested to know how effective odor control can really be. I too am preparing for a grow, and my femme fatale is concerned about the potential for strong odors. To assuage her concerns I told her that she can tell me to shut down the...

Yesterday I was informed that I'll be spending a week in December with the in-laws. Although I will be growing from clones, I think late August to late December might be cutting it close for a newbie's full grow cycle, especially with curing time. I suppose I could just go to flower earlier...

I'm going to need a bucket to catch all this knowledge raining down on me from everyone! You saved me from likely disaster, Prairie. A two-day camping trip could have really hurt them. Five gallons per plant it is. So looks like I either grow one plant in my 5 gallon or I return it and get...

Thanks PrairiePoet, I was wondering about that myself. So would a 5 gallon tote be big enough for one plant? Or, how big of a tote would I need to grow two plants?

Yesterday I purchased a Sterilite 5-gallon storage tote ($4 at wally world), some ph calibration fluids ($8 each at the local hydroponics shop) and a few 4-inch net pots ($0.60 each at the hydro shop). I think I'll do two plants in the 5-gallon tote. I plan on using a water pump to feed...

You must be pretty darn pleased if this is your first grow. Looks professional to me! I can't wait to see where it goes from here. :popcorn:
