Early flowering leaf issues??? Pics

[canes177]

The plants were just switched over to 12/12 they are only 10 days into flowering. I am not sure of this problem, I haven't seen leaves that look like this. The lamp is a 400 Watt HPS and it's a foot away from the tops of the plants. I have been using nutes but gave them the first blooming nutes on the 15th a week after switching the lights. Is it burn?

The leafs are only infected towards the top of the plant. Should I remove them or leave them alone?

Any advice please help.

it sure looks like it i had this problem early on, all you need to do is flush your plants by giving them lots and lots of water. either there nute burned or the ph level of the soil is off if you have a meter check the levels they should be inbetween 7-8

inbetween 7-8? During veg I think its suppose to be 6-6.5 and during flower can go down to 5.5. 7-8 is too high I have been told and will lock out nutes..
