If your organic than try flushing the soil.....add water to the top of the bucket slowly till its seeping out of the bottom, hold the bucket up so the water does not collect in the bottom of the bucket. if its a 3 gallon bucket, run about 2 gallons of water through the bucket..SLOWLY. this will flush out the nutes/ferts in the soil. dont water the plant for a few days and pull your lights back for a about 2 cycles, keep them close enough so not to confuse the plant but far enough to minimize leaf burn, as the soil dries to moist insted of soggy..the leaves should start looking better. re-lower your lights and keep on keep'n on...this will rob nutrition from your girl but it is better to be under ferted than over ferted imo. After you have regained controle, you may consider trying to replenish some nutrients chemicaly...I have no advice there. btw, ph your water but dont add any chem's till you have regained your controle...prepair for stunting in growth. This is my opinion by the way and may not be that of others. Take care.
