i have same problem bro
Lockouts are hard to diagnose, especially online.
Could be cold roots at night (less than 19c), nutrient-ratio lockout, or simply the good old PH-lockout.
It is probably related to flowering, as you are only 2 weeks in. Did it look healthy at the start of flowering?
Is this the only plant suffering?

That's a pH problem hombre. Your meter can't measure both the water and the soil.
You look like you could benefit from a bit more Calcium, magnesium, and phosphorus also. Start with a top dressing of dolomite lime, and maybe start including an organic bloom booster. $12 would get you what you need.

Yes they where helty at the start of flowering, I only have one, that's why I'm worried.
Well I have one of those probe one, that can measure soil and water, but how accurate it is, ill never know. I was thinking that, just buying some nutes as I will need them later in the flowering. Will MG 15, 30, 15 do ok?

Google ph & nutrient availablity. I never really checked ph(edit: only when something seems wrong do I check) I flush em the last watering before every third feed with some GH stuff...& if your doing the organ thing (which I'm new to) some dolo lime in the soil & if you havent, as a top dress should help your ph. I think.
Yeah sorry homie not sure what the defs are. But my first guess would be a lockout not a "lack of food" so 2 speak.
P.S sounds like your using a pronged soil ph tester?????their unreliable had 1 not worth the trouble and false security. Get an electronic or use litmus paper your better off.

I agree with Snow...You could use Cal-mag & phosphorus. And get a new PH meter if u can, they really work well, I use soilless med. But I test the PH in H2O & nutr. before I feed & after it runs through almost same. Goodluck & Happy Growing!

Just A note: I have PH meters and after a while they need to be recalibrated to 7.0. U can get recalibate solution @ local grow store.

Really? Can this be confirmed by someone? Its not a lack off food, but a lockout?? I was thinking a lockout effects more then a few fan leafs? I'm using Miracle grow witch provides food apparently for 3 months, its only been 1.5months!?? Just a little info, It was all ok before i started flowering and i use tap water now (used bottle 7.4ph water, was all good) and i now lower the pH with lemon juice, Maybe I put to much lemon juice in there?? Stupic cheap ebay pH meter. I look all over and they don't sell lime here, had a hard time finding perlite.
Please some one help, btw she growing buds nice and without problems.

i have a feeling you did the same thing i just did in my grow, too much miracle grow, a little goes a long dam way, i nutrient locked out my plants just like i think you did. now I'm just letting them sit watering only with fresh water, i hope they recover with out messing with dolomite ect.
this could also be Ph but i think your first problem was too much MG
is your plant looking any better with only water?

Well I'm using Miracle Grow Soil Mix and was never using nutes in the first place, Always just water. The water is from the tap now (from bottles b4) and I let it sit for a few days, I found out that I was underwatering them, so now every 3-4 days, I give them about 2 liters of water in one go.
Any experence grower tell me could this be true.? -> " My guess would be that your plant is starting to eat it's own leaves for food because you havn't started feeding it yet. "
Or are they to young to star eating them self.?
If that's the case ill go but some bloom nutes and take it from there.?

Hey bro hope they are doing better. I was reading ur post, today. If ur not using a air stone (bubblier) in your water already. They r great to put in your reserior, water bucket, etc. So u keep oxygen in the water. You can even get them cheap @ Walmart in the aquarium section. Know this isn' the problem, just helpful hint. Peace

plants dont look bad bro... less nutes better than over nute... im sure miracle grow got plenty of nutes already... are u foliar spraying? n they did look underwatered, give em a good soak n wait few days til top 2 inches of top soil gets dry n water em again... good luck
i am no pro but have done this a couple of times and i have had this same problem every time i flower. I started doing 1 week of nothing but epsom salt between flower and veg and it seems to work. I do have 1 of my 6 doing the same thing now. I just had my ph meter crap out and my new one will not be here till thursday so i am getting worried i will compound my problem. But yes this sounds like nutrient lock out. I dont know why but it happens to me every time. Take a week off of nutrients and then reintroduce slowly and it should fix the problem. You do have to be patient it will get worse during the week but it will fix it. If you do nothing you will have a poor harvest and at the end you will have no leaves left. So the week of getting worse is well worth the alternative. Hope i helped good luck. I am going to pull my one out from the rest and give it a week it is my biggest and hope its a girl.

LOL... 6 weeks too late smart guy.
Funny how noobs do this.
so if he is in lockout how does he unlock it. I thought you had to basically deprive them to unlock. Is this not true? you said to add Calcium, magnesium, and phosphorus. Does that work if it its in lockout. i realize my solution may not work for him, but for "Noobs" advice works better than berating.
