issues starting from the bottom and working upwards are usually related to over nuting. The tips of higher leaves are showing signs over over nuting also...

safest first option.

make sure not to get any nutrient water on the fans when watering

Nitrogen
(Deficiency) Plants will exhibit lack of vigor as older leaves become yellow (chlorotic) from lack of chlorophyll. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.
(Toxicity) Leaves are often dark green and in the early stages abundant with foliage. If excess is severe, leaves will dry and begin to fall off. Root system will remain under developed or deteriorate after time. Fruit and flower will be inhibited or deformed.
Phosphorus
(Deficiency) Plans are stunted and older leaves often dark dull green in color. Stems, petioles may turn purple. Plant maturity is often delayed.
(Toxicity) This condition is rare and usually buffered by pH limitations. Excess phosphorus can interfere with the availability of copper and zinc.
Potassium
(Deficiency) Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken.
(Toxicity) Usually not absorbed excessively by plants. Excess potassium can aggravate the uptake of magnesium, manganese, zinc and iron.
Sulfur
(Deficiency)The initial symptoms are the yellowing of the entire leaf including veins usually starting with the younger leaves. leaf tips may yellow and curl downward.
(Toxicity) Leaf size will be reduced and overall growth will be stunted. Leaves yellowing or scorched at edges.
Magnesium
(Deficiency) The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tips and progressing inward between the veins.
(Toxicity) Magnesium toxicity are rare and not generally exhibited visibly.
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. Buds may be stunted or deformed.
(Toxicity) Difficult to distinguish visually. May precipitate with sulfur in solution and cause clouding or residue in tank.
Iron
(Deficiency) Pronounced interveinal chlorosis similar to that caused by magnesium deficiency but on the younger leaves.
(Toxicity) Excess accumulation is rare but could cause bronzing or tiny brown spots on leaf surface.
Manganese
(Deficiency) Interveinal chlorosis on younger or older leaves followed by necrotic leasions or leaf shedding. Restricted growth and failure to mature normally can also result.
(Toxicity) Chlorosis, or blothcy leaf tissue due to insufficient chlorophyll synthesis. Growth rate will slow and vigor will decline.
Boron
(Deficiency) stem and root apical meristems often die. Root tips often become swollen and discolored. Internal tissues may rot and become host to fungal disease. leaves show virious symptoms which include drying, thickening, distorting, wilting,and chlorotic or necrotic spotting.
(Toxicity) Yellowing of leaf tips followed by necrosis or the leaves beginning at tips or margins and progressing inward. Some plants are especially sensitive to boron accumulation.
Zinc
(Deficiency) Chlorosis may accompany reduction of leaf aize and shortening between internodes.Leaf marins are often distorted or wrinkled.
(Toxicity) Zinc in excess is extremely toxic and will cause rapid death.Excess zinc interferes with iron causing chlorosis from iron deficiency.
Copper
(Deficiency) young leaves often become dark green and twisted. They 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.
Molybdenum
(Deficiency) Often interveinal chlorosis which occurs first on older leaves, then progressingg to the entire plant. Developing severely twisted younger leaves which eventually die.
(Toxicity) Excess may cause discoloration of leaves depending on plant species. This condition is rare but could occur from accumulation by continuous application. Molybdenum is only needed in very small quantities.

give it a week to fully recover then start on a weak solution.
