Whats up Pepurr, looking good man. I have learned that if you cut the bad spots off the leaves, even if it means cutting leaves in half with alcohol sterilized scissors it stops the spread of damage and promotes new growth as long as you are giving it the right nutes and the ph is good.

I am a disabled vet and too have a tight budget but you would be surprised what you can find at garage sales, also I supplement my income by selling stuff on ebay, you can get rid of a bunch of crap you have just laying around the house and make enough money to get a really good setup. My last ebay sale I bought a 400 watt hps light and ballast on ebay. just an idea, keep up the good work.
