Cool thanks. Nope i have zero experience & yea I definitely take advantage of all the professionals present on this forum. It's frankly the best thing ever. I really appreciate all the help. I apologize if I've abused the "take a question, leave a question" Jar. Duly noted
You're not abusing anything but you might be better off starting a grow thread and keeping everything in one place but then you won't have as large an audience for your queries.
A good idea is to create a text file you can past at the top showing all the grow conditions and what you are doing as far as medium, water, feed etc. I believe there is a stickie in the new growers forum that has a form to fill out with all the info that people should post at the top so guys like me can tell what's going on and give you better answers.
Those tips are normal but if they start getting larger or the tips along the edges, (margins), of the leaves start going like that then it's likely nute burn starting. That will happen if you add nutes to something like FFOF too soon or just overfeed your plants by accident.
So your PhD must be in something other than agriculture eh.
