Hey there tippysco.. not too sure about this one. From what I am seeing(although it is hard to see due to taking pictures under HPS light) May be a magnesium deficiency. does the nutes you use contain any magnesium? also, this looks like it could be heat stress.. Make sure if you are growing with HPS, to keep your light at least 1-2 feet away from your plants. The first thing I would do would be to raise the light a few inches and see if things get a little better. Also, make sure the temp never gets above 30 celcius. Thirdly, make sure you are never using more ferts then recommended. The second thing I would try, would be to flush your plants real good to make sure there is no nutrient burn going on. Following these steps should regulate any prblems occuring with your plants.
thankyou for your time stealing i think i have solved this problem i got a lend of my friends ph meter and done some tests on the water and it was showing my ph was around 5.7 to 6.0 i have read that some nutrients can be locked out if ph is not balanced correctly now the water from the plants is reading 6.8 so hopefully this should solve my problem. ive attached another pic of the plant taken with the hps off

i have 3 other plants which are starting to show the same symptoms which have had no nutes yet i will do a ph test on them later. they are all using the same soil so i know its not too much nutes im pretty sure this is a ph problem causing this but i am noob at growing so i could be wrong

hey tipsyco, stealing here again. test your ph, and it should be around 6-7. 6.5 is best. i'm guessing this is the main source of your problem. It may also be phosphorus deficiency, but I may also be completely wrong. i'm sure it's your ph though. Hit me back on this man.
