Yes, That is one of the signs of nitrogen toxicity. Other signs are dark green leaves and the leaves appear to have a sine to them. Happy Growing.

Curling Tips Why do I see those curling tips? I identified them as Nitrogen toxicity coupled with Nute burn, but flushing didn't fix the problem since Veg and I still can see them appearing in new grows. I want to add extra 0-5-4 nutes to help the overall growth of buds, shall I do it?

Dark shiny leaves, Clawing towards the ends. Is this a sign of N toxicity?Hello, I am a first time grower. I have plants going in Fox Farm Happy Frog soil with 4-4-4 Gaia greens dry amendments. I believe the soil is too “hot” and wanted to get your guys thoughts if you agree and if so, what to do. I water every 2-3 days using the knuckle test. Thanks!

What is wrong with these plants?I can't recognize what is happening with the two Gelato plants I have going. The lower leaves are curling down around the edges and all leaves are drooping. Can't figure out if it's over or under watering or some other issue. Any thoughts? Thanks!

THIS IS NORMAL?Tem 1 ou 2 dias que algumas folhas começaram a ficar assim. Me parece que estão a enrolar para baixo ou um pouco tristes, apesar de continuarem crescendo. Gostaria de começar a alimentação delas hoje, mas os medidores de PH e TDS/EC só chegam em 3 dias. Devo me preocupar??
