LED growing- An instructional grow log

Well done sir. Well done.

Nice work, those buds look nice and compact even on the lower branches. Right now I am currently growing c99 from female seeds under a Flowerforcer 900 diode led array. I like led's a lot, hardly no hassle. It has been vegging for about 5 months, to which I LST'd back in january and has still managed to stay nice and compact.
There is another forum on the net for their previous generation leds that turned out fantastic but I must say that the creator hasn't kept up as good SnStealth. They got .34 grams per watt, which is not good but he did not train or correctly place the lights. The link Cannabis and Marijuana seeds :: HomeGrown420 - 140w LED Grow (660/630/470/420) . Thanks for convincing me to get a couple to flower my lovely lady with. by the way I don't recommend flowerforcer they work great for vegging but not for 470 USD. PEACE

the goddamn spotting!!! i have flushed twice, gave Epsom salt, sprayed down with pyrethin twice...spots still coming. plant is growing, but the spots have always been on only 3 plants!!! never more...the big JH girl, one with all the super frosty nugs, now has spotting on about 40% of plant!! i don't fuckin get it... still can't SEE any pests....

I have a list of deficiencies and toxicity from my hydroponic store, im trying to scan it but my scanner is all muffed up...i read it over and looked for anything about spotting and heres what i found,

CALCIUM
Deficiency: Young leaves are affected first and become small and distorted or chlorotic with irregular margins, spotting or necrotic areas. Bud development is inhibited and root may be under developed or die back. Fruit may be stunted or deformed.
Toxicity: Difficult to distinguish visually. May precipitate with sulfur in solution and cause clouding or residual in tank.


BORON
Deficiency: Stem and root meristems often die. Root tips often become swollen and discolored. Internal tissues may rot and become host to fungal disease. Leaves show various symptoms which include drying, thickening, distorting, wilting, and chlorotic or necrotic spotting.
Toxicity: Yellowing of leaf tip followed by necrosis of the leave beginning at tips or margins and progressing inward. Some plants are especially sensitive to boron accumulation.

COPPER
Deficiency: Young leave may become dark green and twisted. The may die back or just exhibit necrotic spots. Growth and yield will be deficient as well.
Toxicity: Reduced growth followed by symptoms of iron chlorosis, stunting, reduced branching, abnormal darkening and thickening of roots. This element is essential but extremely toxic in excess.

I am unclear if it is any of these deficiencies but i hope itll help you out a little bit..im going to fix my scanner and if upon anyones request i will post the informative paper on here. Sorry if it doesn't spring any clues!

Potassium deficiency from high soil pH. Flush, return it to 6.7, foliar with a complete fert with micros. It won't go away (scarring) but it will stop progressing.

The def charts and guides are linked around here somewhere though... I think in plant problems?

[Weedhound]

I agree.......lower soil ph.........Stealth I found with my plants that fans blowing on them made the K def worse....I think by lowering humidity around the plant. Are these plants being blown on by a fan?

[SnSstealth]

that they are ma'am...and with relatively no heat...maybe stressing more than helping? what would you suggest to fix the K def? all my nutes have plenty o potash...should fixing the Ph also fix the K def?

Lose the fan directly on them. I'm definitely with Stinky on lowering soil ph....it's the only thing that's similar to my hydro plants with the exact same symptoms...

[stinkyattic]

Exactly. You HAVE the K, it's just unavailable.

[Weedhound]

I told that damn K to get OFF the cellphone...........and not to brings its phone to work anymore so it would be available for things like this.........:wtf:
