dying seedlings too much fertilizer reduce fertilizer, or keep away from tender roots
dying seedlings too much fertilizer water to wash excess fertilizer out of soil
dying seedlings too wet don't plant seeds in wet soil, give more drainage
fruit/veggies rot infected with something pull infected plants to prevent spread
fruit/veggie rot infected with something stake plants to prevent contact of fruit with soil
half chewed leaves slugs are eating me place dish of beer by base of plant to trap slugs
healthy leaves, no flowers needs more light move to area with more light

no fruit/veggie production insects are eating me remove insects, wash with soapy water

warped leaves infected with something cut off affected areas, diagnose pathogen
weak, leggy plants need more light move to area with more light
weak, leggy plants too crowded separate from other plants
weak, leggy plants too much nitrogen reduce fertilizer

white spots on leaves or stems spider mites are eating me remove insects, wash with soapy water
wilting plant infected with something cut off affected area, diagnose pathogens
wilting plant too cold put in sheltered area
wilting plant too dry water
wilting plant too wet check roots for rot, give more drainage
