Pics 2 and 3 looks like maybe good ol simple nitro deficiency, but don't quote me as an authority and wait till one of the grow eggheads confirm it or otherwise. As for your other question concerning I presume an upcoming urine test, I do have considerable experience of this fascistic practice. Unfortunately the way you are looking at it is mostly a no go, there is no magic potion to make you pass a urine test, time and abstinence are the only sure way. The good news is that that unless you are a complete heavy duty stoner the figures quoted usually as 30 days abstinence are way too high, you can if you are a moderate smoker, and by moderate I mean 2 or 3 joints a day/night then you can be below the limit ( usually 50mg ) after a week. How can I be sure of this ? I buy drug testing kits and keep an eye on my own condition and will confirm that I will be clear after a week. You don't say if the urine test is for a pre employment or a test during employment, but either way with a weeks abstinence you can pass it. If it is a heavy duty test like blood or hair tests then its bad news--then the 30 day rule is valid, post back with any details you care to share and I'll try and advise, otherwise good luck. I kneel by my grow cupboard every night and pray that this MJ testing regime one day will be outlawed as the offence to personal freedom it undoubtedly is.
