3rd week flowering and having some issues. Pics attached...

I have been using the Fox Farm soil and nutrient schedule the entire grow. It was the first batch of flowering nutrients that seemed to have caused the problem. It was the first dose of Tiger Bloom they were given and it seems to be affecting one more than the other two.

I am growing under CFL's using approximately 400W. I flushed all three with PH'd water and they do not seem to be getting any worse at the moment. I did notice some leaves have almost a plastic look to them and they are starting to get a little brittle. Looks like the brown spots follow that shiny look.

Also the veins in the large shade leaves is where the discoloration seems to be begin. The other characterisitics are the leaves that are curling down and almost rolling up. They are being watered about every 3rd or 4th day right now.

Any help would be greatly appreciated!

possible humidity. and mag def.

flush it with pure water so a 2 gallon you would need 6 gals of water and so on 4 gal is like 16gal so just tripple the mass of you medi.

Thanks guys. I have switched to the Fox Farm flowering nutrients and the they are certainly starting to flower. Lots of hairs growing all over the place. The actual flower leaves look to be ok, it is just the older and larger shade leaves that seem to be experiencing the problem. I have a weather station in the room and I am running at 78-79 degrees F and the humidity is right around 38-40% so I think I am good there. I really think it was just a little bit of overkill with the nutrients. I am going to use only water for the next couple waterings and then ease back in the nutrients.

I don't think it is a deficiency though as they should have plenty of nutrients and the leaves definitely have that crispy feel to them as if they had been burned. Thanks for the info though.
