Hopefully you guys can help. I looked through the faqs but couldn't find anything. This plant was ok yesterday. Today when the lights came on I noticed all these spots. It is the worst around the top, with just a few spots on lower leafs. I have been giving them Tiger Bloom nutes. Not exactly sure of NPK ratio since it was donated.

Please help!!

hey what is your growing method (soil,aeroponics etc) what is the ph of your soil/water? think you might have a ph problem. dont use any nutes flush with bottled water with a ph of around 6.5. check out this thread look down at ph problems these spots occur just before nute lockout. http://www.icmag.com/ic/showthread.php?t=11688

Thanks k3nz, Thats a good thread. Just like the faqs here it doesn't look like any of those. It maybe in earlier stages and will get worse.

I'm growing in soil, have no way to check PH. I know there are lots of thing that can affect PH, but i'm growing in the same soil and watering with the same water. Wouldn't it show up on others?

like you said it could be the early signs of a ph problem and the other plants might also get these spots in a few days. just use water for the next week and see if it gets better then water using this schedule: water-water-feed. hope your plants recover man

Overwatering? No nutrients?. Ph adjusted water? Tap water can be hard. 6.3 ph for soil will make a difference.
