like I said this is my first time , I don't have a ph tester yet .I don't get around very well so I on line order a lot of things and the ph tester is on the way.So all I can do is try to describe it to you the best I can, till I get the pic thing fixed Im growing in soil black magic , I got the plants at 8 inc tall 45 days ago they are now 2 feet and still growing.
Did any of the plant pictures that I linked look like what you have?

OK ray, we are making progress. thanks for the info.
so let's see where we stand:
growing in soil called black magic and plants are pretty large at this point
first problem, you are using hydro nutrients for a soil grow. AN sensi is their hydro line of nutrients.
do you order everything online? or is there a grow shop nearby? my first suggestion would be to start simple. if i were you, i'd get a bottle of general hydroponics floranova bloom. it is for hydro or soil grows. and there is a nutrient program/regimen called the Lucas formula. it is the simplest way to feed marijuana. and it works. all you need will be "pure" water: rainwater, or reverse osmosis, or distilled that you can get from walmart. and the floranova bloom.
i've never done a soil grow but SME or some of the other dirt farmers can chime in. i'm not familiar with black magic soil. or what it has in it.
where do you get your water from to water the plants? are you on city water? if so, you'll want to let it set overnite for the chlorine to dissipate. that's why most growers want to use "pure" water. there is nothing in it but water.
understand so far?
we are trying to do 2 things: figure out WHAT the problem is but more importantly, WHY is there a problem. the more info you provide the better.
The Lucas Formula was actually designed for hydroponics so it might need to be tweaked for soil.
It appears to be magnesium then but that could be from bad water, pH issues or just not enough mg. Try a foliar feeding, when the light is on, with epsom salt at 1/2 tsp/quart sprayed directly on the leaves, top and under. If they get better fairly quickly you just needed more. If not, you have other problems that require the info RKY asked for and/or a pH meter. Maybe even a ppm/EC meter depending on your water source.

I have a fresh water fish tank 75 gal I use the water out of that or distilled water the sensi nut said on the back of the bottle its good for all types of grow mediums, right now im using half strength on nuts the spots are getting less and less so it looks like it is working , thanks for the help.
I just switched them over last night to the 12/12 , they are looking much better . nice and green ,I need to get some pic up so you can see how they look.
