Yesterday Everything was fine' can anyone help grow in 400w PH seems to be ok 6.5, the leaves are not yellow it's the camera low lite affect pleas help me quickly before it will be to late
Man that hurt my eyes, looking at that, but from what you describe & what I think I see is heat/humidity issues the leaf margins are curling upwards to stop transpiration try raising your lites 6-8 inches and take more pics with more lite 1. hydro, soilless or Soil & brand name of soil ? 2. PH of reservoir solution? 3. PH soil runoff? 4. PH of water? 5. Age of plants? 6. What Fertilizer, dosages, and frequency? 7. lites, wattage & proximity to plants 8. Light cycle. 24/0,, 18/6,, 12/12? 9. In light cycle how long? 10. Room temps & Humidity or reservoir temps
looks like heat/humidity stress ....again raise your lites the other thing that can cause this is a magnesium def. but you would also see yellowing between the viens of the leaves
