None of the new growth has it but its happening on both of my plants. They are 4-5 weeks into veg. I'm growing hydro with General hydroponics nutes only. It is not nute burn and at first I thought it may have been light burn, but I moved the light and more leaves are being affected. I'm thinking either phosphorus or calcium deficiency after reading but I can't be certain. I would post a pic but my camera cord has been missing. They look terrible. Is there any thing around the house that could be used for a plant calcium supplement.![Crying or Very sad :cry: :cry:](/styles/smilies/icon_cry.gif)
EDIT: alright, I just added 2tsp in the 5 gallon and 1 in the 3 gallon of GH Bloom which had the most phosphorous. Which I guess makes sense since the plant is getting older or whatever. The ph is fine and everything, So I think this should fix the problem. This is my first time growing and I've already had mag deff, nute burn, light burn, and now phos deff. hopefully next time itll be a smooth ride to harvest.
