could be calcium deficiency.. when this happens your leaves turn brown on the ends or just cripple slowly but still live..

--to fix this problem get some hydrated lime and add about 1 tsp per gallon of water you use..

could be magnesium deficiency... to fix this add about one tsp of epsom salt per gallon of water you use..

make sure stuff is disolved, use hot water..

also, make sure water is right PH.. I Reccamend distilled water, works the best!
L0r6dIN6faM6ous Reviewed by L0r6dIN6faM6ous on . What causes this? (pics) Temp: 80 soil Ph: 6.9-7.0 Soil: (according to my soil meter) moist - not too wet, not too dry Light - 400w HPS Nutes - Was overfertilized 6 weeks ago. Emergency flush and transplanted into new soil w/o any ferts or nutes. Gave it some tiger bloom two weeks ago at 25% strength. The leaves have always looked like this even before I overfertilized two months ago. I thought they looked like this because of lack of nutes in which I accidently overfertilized So I had to do an emergency flush Rating: 5
