Leaves coming out funky, ph issue. Check your runoff ph and ec and get them in order. Look for a soil ph of 6.3 to 6.5 for veg. Around 1.8 to 2.0 ec. Dont give to much extra cal/mg. Keep the plants where the back of your hand feels comfortable under your light. They look like their canoeing. Heat, light stress? Cheers

Nitrogen Deficiency or Light Burn.How can you differentiate between a nitrogen deficiency or too much light in an organic grow when only the tips of bottom leaves are affected? I am using 60 led lights on one plant (Wakyme).

Upper growth leaves and buds on one plant are burnt. I attributed this to light damage and raised them up a few inches. If anyone has any alternative thoughts or suggestions about how to minimize existing damage that would be great. Other bud sites look fine.

Please look at last picture - there is an area of crispy brown on the lowest leaves of the Red Diesel. I'm thinking it's a little bit of light burn, but am not sure. Any thoughts from any of the experts?

Droopy leaves on a seedling in dwc top feed system. Would you think it's caused by (1)low temp (16°C),(2) low dissolved O2 due to small air pump making Large bubbles, (3) lack of nutrients due to still being on seedling feed schedule, (4) low humidity.
