So LOST??? Please some guidance appreciated.

Okay I need Help. Originally seemed to need more nutes, so I gradually began introducing them and half slowly reached to maximum recommended strength.

What is your experience level? ( novice,.)

.4)(Incoming air)
Yes Incoming Temp 55(L)68(h) humidity 53 percent(L) 99 percent(H)?
.5) Do you have an exhaust fan and a circulation fan?
(Exhaust yes/ Smal area I assume the air in and out if plenty air flow/ however there is 4 computer fans rigged into my reflector pulling hot air from lights towards top of compartment and out towards exhaust fan.
.6) schedule?
12/12

Your medium:
Sphagnum Peat,Vermiculite, Perlite, topsoil (1/1/2/4) very very small amount of epsom salt, hydrated lime(to compensate over time and Peat Moss Ph raising? and a small handful of Chickity Poo in about a 10 gallon mix{intended to add a bit of Nitrogen for vegg period) 6.8 soil ph
.8) (Pot)
-About a gallon
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?
Germinated Paper towl methid into jiffy pop up seed starters then to soil when taproot exposed out the bottom)

Your nutrients and water:
10) Source of water? (tap, bottled or filtered)
Tap Water filtered through brita faucet filter, usually alowed to site for minimum 24 hours before use.
11) Method of checking water ph.
(strips)
12) Method of adjusting water ph.
(None yet))
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
Miracle Grow Tomato plant food (no comments on Brand Please I know a handful of people who have successfully used)
18-18-21
14) How often are you watering between feedings, and how much per watering?
Just enough to come out the bottom and currently fed every other water past few weeks progressing from 1/4 strength to full strength last water. Day of pictures above).

16) Are your ph levels stable, or do they fluctuate?
Seem stable
17) What is your ingoing water's ph? ...your runoff ph?
6.8 before nutes 6.5 after/ runoff 6.6-7
18) Do you foliar feed?
Twice few weeks in Veg when symptoms began showing rapidly.? 1/8 strength of recommended watering mix ratio.

Now you know someone who used the mg and it didn't work. 18-18-21 is not for flowering and way to hot it kills the microorganisms in your soil that feed your plants. The numbers don't mean anything if you read the ingredients it will say "usable" or "available" those are the numbers that count. Get a flowering fert lose the mg......

I have Peters Blossom Booster 10-50-10 however, I have been battle what I thought was a total nut shortage, defin. think nitrogen and that why I have yet to change to a flowering nutrient. I am trying to figure out if I have a deficiency or over fert... The problems have remained the same despite my increase of nutrients. So as of right now Im flushing them all and hoping maybe it was some sort of salt or mineral buildup. I have very limited resources in obtaining nutrients and postal is not an option atm, Sooo Im attempting to do the best I can with what I can find. I just need a little direction in whats Im lacking or possibly overdoing.

I agree with Lipps thoughts. I would guess too strong of nutrients. Try a flush (run about three gallons of water through the pot). And then let it dry out.

Yeah, its not a nute deficiency, its nute burn. I also used to use MG, it seems that MG, since they're just a general fertilizer and not an actual nutrient, tends to just let it slide if we 'accidentally' knock a powdered case of nutes into a container, why? because tomatoes and veggies eat them up... I have grown MJ using MG successfully, but it was in an outdoor garden, using the MG foiler spray that you attach to a hose, and it was more or less an accidental grow.

1/4 strength using MG is WAYYY too strong, and as already been pointed out, even using MG at 1/4 strength you don't have the right compound to flower. I have however used the MG bloom booster which is 10-10-60 (I think) successfully at 1/4 strength during flowering. It is SPECIFICALLY for roses, and did quite well on my cannabis plants for a single grow (didn't use it after)

Good luck bro, everything else looks good!

Thanx buds, Life savers. I did a flush last night and Ill be changing nutes hopefully when they recuperate.

Ok so its been about 12 days and other than the purpleing on the stems seeming to be reducing the leaves still show the same symptoms. Im probably going to flush again any other suggestions. I though about doing a controlled test and group them into two groups so I could try two different ways of treating. Hopefully then I would at least save half and get at least one mother to clone. For tonight I will just flush . I have been taking photos of each one individually every day so I could look back and track progression.

hey guys a nute burn would not get it to yellow up it would get it to wither and turn brown and die. i bet this is the ph thats not stabilized

yut, well the yellow leaves could be N lockout. Yellow is usually, too wet, too little Nitrogen or no iron ( a micro nute).
But I think it still could be too much of other nutrients. So both at the same time, toxititiy, deficiency. It could be, right? :)

ye shovelhandle It could be :)

but this is a nutrients burn can you see ? http://boards.cannabis.com/plant-pro...-problems.html

The old leaves will not return to there original color watch the new growth that will tell you what is going on....

Those leaves are STARVING for Nitrogen bro!!!!! Hands down!

Either:

A: You aren't feeding enough nitrogen.
B: Something is inhibiting nitrogen uptake.

Hope that helps!
