Over feeding?

A second opinon would be very appreciated. I had the same problem I grew this strain and was dumb enough to do it again. She's a White Russian from Serious Seeds. I'm growing her with three different strains, last time it was two, that are on the same feeding schedule that are happy and healthy. I'm using fox farm nutes and soil with a 600w hps. She's been on a 12/12 light cycle for four weeks now. I flushed her out with some Sledgehammer and have only used water and a shot of superthrive once since.

thats phos your in flower either you gave them to much which has effected you notice any red on your leaf stems thats your issue to much P will interfere with Mg, calcium, Fe, and copper what i would do is flush medium with mild fert

I cant say from the pics what your particular problem is, but ill post this document I have for you: Good Luck hope this helps. Here is a simple list of general marijuana problems and how to solve them. Always feel like this one I need to put up on the forum once a month or more often for someone lol.

NITROGEN (N) Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

PHOSPHORUS (P) Slow or stunted growth, red stems. Smaller leaves that are dark green. Lower leaves yellow and die. Add chemical fertilizer containing P. Affected leaves will not show recovery but new growth will apear normal.

POTASSIUM (K) Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

CALCIUM (Ca) Lack of calcium in the soil results in the soil becoming too acid. This leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar feeding with one teaspoon of dolomatic lime per quart of water until condition improves.

SULFER (S) Plants suffering from S definciencies exhibit yellowing of new growth. Mix one tablespoon of Epsom salts per gallon of water until condition improves.

MAGNESIUM (Mg) Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

IRON (Fe) Leaves on growing shoots turn pale and veins remain dark green. pH imbalances make iron insoluble. Foliar feed with chemical fertilizer containing Fe or rusty water.

MANGANESE (Mn) Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

BORON (B) Growing shoots turn grey or die. Growing shoots appear burnt. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water.

MOLYBDENUM (Mb) Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.

ZINC (Zn) White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.

OVER FERTILIZATION Causes leaf tips to appear yellow or burnt. To correct soil should be flushed with three gallons of water per one gallon of soil.

For the record each of the elements listed on that is for deficiencies not if your over on a nute. Generally Speaking.

Thanks for the responses

No Problem, update us once you figure out and solve the problem. The more knowledge on here the better!

Peace and Love,

Happy Growing

So you flushed and does it look any better? because if fluching didn't work you either didn't use enough water for the flush, or that wasn't your issue...Hard to figure out with the FF soils too...lol. When you flush you release more nutes into the soil...so the first flush isn't too great...Anyway, some plants just look like hell I think. I have a C-13 Haze that just can't have grow nutes...like at all...I have literally just dipped a popsicle stick in the grow nutes and then stirred it in the water, and it makes her look unhappy... So, all you can do now is try again...flush again and add like less nutes than you used before and add some CalMag if you haven't been doing that...As for the other plants that look good they are a different strain so it's not the same...I have a few C-13 Hazes and a Rocklock and when I give the Rocklock nitrogen nutes it grows like mad...but if I give any to the C-13s they faint over like freaking Scarlett O'Hara!...So I am just not going to give any C-13s anything but water til 3 weeks into flower or so...I ordered one C-13 Haze seed 2 years ago, and have been growing and cloning the one plant over and over and everytime I get a little better with her...I am starting to feel pretty good about it this time....So hang in there... I think it is more beneficial to growing as a gardener to grow better weed that is harder and learn...I can grow the C-13 so any of the indica strains I get are CAKE! I ordered some Indicas just to make sure it was the plant and not me...this time the Indicas look perfect and huge, and the C-13 Haze has a serious case of the claw leaf, but that is a huge step up from a serious case of the dead, dry, burnt, brown leaf that I have caused in the past...
