???? a ma kdo idejo?

[borat]

pomoje pajkci

[jimmy20]

pajkci ne nardijo tega. prej bi reku da je kakšno hudo pomanjkanje

[weedster]

ja lahko bi malo več informacij podal ne .. pa kako sliko cele rastline .... drugače pa mi zgleda kot pomanjkanje Ca ali pa Mg zaradi premalo informacij te teško povem vsaj imo je tak, ki se je začelo pojavlat zgoraj proti navzdol al obratno?

[zacetek]

slike nimam! večina so taki vlki listi po celi roži razen na vrhu. zalivam jo skos s TNT komplex-hesi, zadnič sem še dodal od Bionove the missing link, zdj pa nevem ka bi lahk blo. Weed katero zadevo priporočaš da ma velk ca in mg vsebnosti? hvala pobi

[weedster]

če novi poganjki niso taki potem je pomanjkanje Mg-ja vsaj imo, žal ne vem kaj ma veliko mg

Na nekaterih rožah sem sedaj, ko je po nekaj tednih dežja začelo sijati močno poletno sonce opazil rjave ožganine/fleke, ki se širijo od konic proti sredini lista večinoma na novih listih. Pojavilo se je le na nekaterih rastlninah. Ali gre za šok ali kaj podobnega? Po deževju kar na enkrat tako močno sonce in jih je požgalo? Ali gre za kakšno pomankanje ali predoziranje? Drugače pa rastline niso bile še nikoli pognojene rastejo pa v dobro pognojeni zemlji z konjskim gnojem seveda takim kateri je stal kakšno leto ali dve. Mogoče preveč dušika? Še slike:

jou, mene pa zanima zakaj bi roži primanjkovalo MG?

Mg-deficiency is pretty common since marijuana uses lots of it and many fertilizers don't have enough of it. Mg-deficiency is easily fixed with ¼ teaspoon/gallon of Epsom salts (first powdered and dissolved in some hot water) or foliar feed at ½ teaspoon/quart. When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil for Mg. Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.

Magnesium (Mg)
Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.

Magnesium (Mg) deficiency:
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.
Notice how in figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.
If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.
Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.
