Please Help. I have 2 plants pure power and pure gold, I have been having problems with leaves browning and dying on the pure power. They were root bound last week in their 3 gallon pots and i transplanted a few days ago into 6 gallon pots. They perked right up and the gold looks great but the power is struggling, ill post a bunch of good pics in a few hours after my class.

Any advice would be awsome, thanks in advance.

One more of the pure pwers leaf problem and here is the pure gold which seems to be doing fine in the same conditions.

Starvation is not a valid growing technique. Even if all you give them is Grow Big...I'd feed those ladies per the Fox Farms Feeding Schedule. Fox Farms Feeding Schedule...
Just went 12/12...? Grow Big is not a bloom fert, so you'll have to make changes there. I'd go with the Tiger Bloom. (I use Fox Farms myself)

A little low on the ph, as ph in peat-based soils drift downwards. it's nothing major yet...but something to keep in mind.

what i was saying is that i fed them grow big once during veg, i am aware that it is a vegging fert and i have tiger bloom. im just afraid to use it because when i used one teaspoon to a gallon of the grow big a while back it burnt the tips of the leaves. I want to use the tiger bloom but i dont want to burn them again. How much should i use to a gallon?

they look like they are a) a little over-fed and b) a little under watered.

With fox farms and happy frog soils you shouldn't have to feed anything for 20 days. (I've heard 30, but my plants have said differently)

I'd water with cal-mag, then water a little more often. stick your index finger deep in the soil -- it should feel slightly damp when you water, not bone dry.

If you don't have cal-mag, sprinkle 1tsp of epsom salts (magnesium salt) on top of soild to leach into with each watering.

thanks a lot guys, i think next time i water ill use like half a teaspoon to a gallon of tiger bloom and ph it to 6.8 and then next time i water ill use a teaspoon of garden lime to a gallon. I limed them a while ago but it might have worn out by now.

[HighonaMountain]

yo rusty, do u follow the ff feeding schedule exactly and do u water w/ straight water in between or what? what amt. per gallon do u start with?

[HighonaMountain]

So i just got done giving them 5 cups each out of a gallon of half a teaspoon tiger bloom, and one teaspoon lime. Thanks for the advice guys ill let u know how it turns out, any other advice would be greatly appreciated.

I use the Fox Farms schedule, but I feed twice weekly, at half-strength dilutions. Same totals weekly, and the sativa's don't burn as much. If growing only sativa doms, I will flat-out cut back on the Tiger Bloom dilution. (3/4 strength, or so) If you use Big Bloom, half-strength is fine through to harvest. Adjustments may be necessary, depending on additives, soils, ammendments. Before I feed the ladies, I'll pour some plain, ph'd water in, (about a quart per 3 gallon pot) to start the absorption of moisture, and help keep my nutes from draining-off. (a waste) I wait a couple/few minutes, then add nute solution till slight runoff.

Keep in mind, too...Per Fox Farms...you have all the micro's you'll need in the Grow Big, and the Tiger Bloom. (Big Bloom is the catalyst) I do add humic acid after monthly flushes, (to relieve salt build-up FF is notorious for) and an occational shot of Sweet or molasses. (carbs-n-stuff)

Plain, ph'd water between feedings, if necessary. I never foliar in flower, unless it's to correct a defeciency or bugs.

Don't know if all this works best, but it works best for me. :thumbsup:

Also, if you're going to be using a pre-nuted soil, adjustments must be made to pull it off. The nutes in stuff like Miracle Grow lasts cannabis about three or four weeks in veg, and about two to three weeks in flower, before low-doses of nutes should be attempted.
