Discolored leaf edges
hellomynameisstarted grow question 4 years ago
Organic Grow: Edges of leaves turn brighter starting from the tip of newer leaves. Old leaves start to get hard and brittle. The issue appeared between week 3/4 before adding any fertilizer except Root Juice. I water with stale tap water like always. Check last two photos W4.

Lights are too low my good man. In this stage of growth you want to be at about 23 inches with the sf1000. Happy growing.

I get the same thing and grow the same way.. I have no idea yet y it happens to me either.. but hasn't seemed to ever become a problem or bother the plant. Always seems to just stay like that.

A deficiency, a toxicity and a toxic-deficiency???Here's what I make of it (and PLEASE correct me where I am wrong!) :
The tips yellowing indicates, a nitrogen burn.
The burnt brown tip indicates, nitrogen burned to long 😂
The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)4 days ago

Brown/burnt spots on 1 plant onlyHello,

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.Leaves. Edges burnt
