Noticed a problem last night with my blue cheese in soil. I'm guessing something to do with pH. I broke my meter the other day. The leaves are looking burnt and are drying out quickly. Its only happening on the tops near the buds. Ideas?

I don't think so. They've been the same distance since starting them.

The leaves are very dark which is a characteristic of nitrogen abundance.. Not sure though

Its is under a 150 and 70 hps. Don't think its lights. I use farm farms nutes. Looks like they got fried. Maybe I was to blazed mixing nutes and accidently doubled up.

Any other ideas? I dropped several lower leaves overnight. I flushed this morning. Hope it helps.

boric acid could help, its in the eye wash section, contact lense cleaner. but not sure about that. could still be molybean or copper.
