Blight in my ground

[suzqz57]

I have blight in my dirt and is getting into my plants I have been using neem to keep them good but now they are starting to bud what can I put on them now that won't ruin the bud

Can I put copper fungicide on my plant after it buds

I wouldn't use the copper in flower. What kind of blight do you have? If it's the early or late blight that is common with tomatoes it shouldn't affect cannabis plants. Can you post pics of the issue? It's normal for lower fan leaves to yellow and fall off in flower .

"Blight" is a dificult term to diagnose. You could have fungal, insect or nutrient/pH issues. Using neem oil is an insect problem treatment, but (no offense meant) are you sure it's insects? Orggrwr is right. Need pictures and better descriptions to even make a guess.
"Blight in my dirt"? Tell me you didn't put a shovel full of yard dirt into your indoor grow pot! That introduces insect eggs and fungal spores! (Assuming indoors - outdoors totally different.) I would get past this grow, clean everything with a 50/50 water/bleach solution and start over with a sterile grow medium.
Read! GWE has tons of excellent tutorials.
A successful grow is a planned grow. Too many newer growers think dirt, pot, seed = big frosty nugs. It is almost that simple with the proper techniques. But, that knowledge takes a few grows and making the necessary mistakes to learn from. Keep trying. You'll get there.
