Need some help....Any advice welcome

i have a couple plants that are showing some type of deficiency (mainly R2D2), i cant point it out exactally so im going to try flushing because im not sure i balanced the ph properly, heres some pics of my plants, im sure you guys can decipher the problem.
IMG_0626.jpgThis is on My R2D2

IMG_0628.jpgThis is on my Pineapple Chunk, it is on its own 600w by itself. im thinking its the heat but not sure.

IMG_0632.jpgThats how far they are from the light, other plants show some signs but as bad

IMG_0633.jpgcloser view of some of the PC leaves on the plat under the 600w. i believe it is hung too close, the leaves are curled like a v

IMG_0634.jpgthe leaf closest to the light is only at 75*

On another note, temp currently runs about 70-75 during day an 60-65 night
im currently using verde, calmag, root stimulator (looking to brew my own nuits but am clueless on to how i go about it). I have 2" of hydrotin pellets at the bottom of the 5gal buckes with the rest coco-grow. for me it drains very nicely, water every 2 days. im open to try new nutrient regimes as i havent started flower yet. i have been using pure flowers and SuperNova but a buddy told me that Pure flowers is really a systemic pesticide and NOT a bloom booster. "Just because a product may help flowering does NOT make it a PK Booster as it is usually called." so i am now unsure as to what i'd use now. beastie bloom for macro and supernova for micro?

-Thanks MM

Thinking its a calcium/magnesium problem. Had mine look similar to that once before (Well more then once >.<) and that was the problem for me. If that is the problem, it wont go away just slow and stop with cal/mag. Also heard of people using epsom salt as a substitute, I dont recomend this and suggest you research if you want to find out more. Hope this helps.
