Questions about either pH problems or nute burn? PICS!

Wondering if the Starburst OG plant I got is pH or nuteburn? Leaves are crisping on the edge and curling to the left/right. Half the blade is yellowed and the other half is green. I bought as a clone of CL. Had issues from the beginning but the buds were swelling up until now... I believe it could be Phosphorus and Sulfur def.... Anyways, here's some pics:

Here's the problem plant-

Also wondering why this Game OG isn't swelling up and why its so leggy? Any opinnions/suggestions/advice is much appreciated.

BTW
Soil - FFOF and Recipe 420, nutrients all ½ strength cause im week 3 flower- d9 double or nothing, d9 silicate, d9 ocean grown, botanicare grow and bloom, hibrix molasses, aurora soul synthetics, and hormex (at full strength), 400W HPS hortilux eye, temps around 80 during lights on, 68 during lights off. Lights are on 630p-630a... Anymore questions about environment just ask!

Looks like nute burn to me, although heat can do the same thing.

Are they really as dark green as they appear in the pics? If so, too much N might be your problem.

Haven't ph'd soil or run off but solution is always at 6.2-6.5 and I've fed ONCE with 5.9-6.0 shouldn't be too much of an issue though :/ lemme know

Also, pretty concerned at this point- is this TMV? looking at pictures the answer seems pretty clear. Or is it a severe def.?

[h=3]Manganese[/h]Manganese is involved in the oxidation reduction process in the photosynthetic electron transport system. Biochemical research shows that this element plays a structural role in the chloroplast membrane system, and also activates numerous enzymes.
Manganese Deficiency
Interveinal chlorosis of younger leaves, necrotic lesions and leaf shredding are typical symptom of this deficiency. High levels can cause uneven distribution of chlorophyll resulting in blotchy appearance. Restricted growth and failure to mature normally can also result.
Mn gets locked out when the pH is too high, and when there's too much iron. Use chelated Mn.
Manganese Toxicity
Toxicity:Chlorosis, or blotchy leaf tissue due to insufficient chlorophyll synthesis. Growth rate will slow and vigor will decline.

[h=3]Potassium (K)[/h]Potassium is involved in maintaining the water status of the plant and the tugor pressure of it's cells and the opening and closing of the stomata. Potassium is required in the accumulation and translocation of carbohydrates. Lack of potassium will reduce yield and quality.
Potassium deficiency (K).
Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.

No light leaks that I know of. I layered my doors to eliminate as much light leak as possible. Ie the light has to bend around 3-4 180° turns to get out if that makes any sense.

Light Leak won't cause that, It has to be a deficiency. Ph lock out can cause this thats why I asked about PH.

Agreed!
Those are really dark.
I'd guess you're flooding it with N, and like I always say, too much N in flower will inhibit flowering.
The yellow tips, I wouldn't be too concerned with right now, but IDK how much if any Ca it is getting with all that you're feeding, and as far as lanky, it's your lighting.
Tell us about that.
