Hey guys, Im 6 weeks into another grow and I'm running into some issues.
I don't have any way to test my soils ph, *but the brand is Dr Earth pot of Gold. With some added perlite. I've also fed them a tsp. Of jobes organic tomato fert about 2 weeks ago. If any more information is needed just ask I just really don't want to lose these plants. They're northern lights btw, from nirvana.

looks like it might possibly be a calcium deficiency, if you have only fed them a tsp of jobes and it was almost 2 weeks ago, the plant is probably needing to be fed more often. Maybe try a water,feed,water,feed cycle and see how that goes.

looks like they have enough N right now, id just give them a couple of waterings with just cal-mag, then pick up the nutes half strength and go from there

 

[Illicitmango]

Thanks guys for the info. To me, it looks like rust on the leaves starting to come through. But everybody's leaning towards a calcium/magnesium deficiency?

 

[vostok]

easier to cheat and potup

this time to a 50/50 mix of ur soils and perlite

no nutes for 2 weeks

and a 50/50 mix of warm whites to ur cool white cfl's

will make you grin too

good luck

Rarely would this be a Mg def or Ca.def,

in most cases Mg.def is seen on much older plants

nth americans have way too much Ca in their water, anyways

unless you have minimal Mg in ur soils..go check?

swim pool Ph strips at ur local drugstore for $5.00, can help...

but a budding gardener would avoid the Ph ..thing

and develop 'instinct?..lol

and don't go all psychosomatic after you look. one thing at a time, if you try to do multiple things at once, it won't go well

 

[Roger A. Shrubber]

it doesn't look like mag, but it sure does look like cal., i'd give it cal mag once or twice, and throw a spoonful of garden lime on top and let it disolve as you water. that soil looks hot as hell, but it ought to be in the ca-mag ph range.

Great. I have two sites on plant problems. Neither worth a flip. This is best I have seen in a few years.

Guy on the right rear could have a Nitro. deficiency

Yea. buy your pens so you can get a grip on your PHs and PPMs

@Roger A. Shrubber
I know you replied and suggested a fix lol. I worded my question wrong, I was meaning to ask is there any simple or quick things I can do to pin point the issue. I trust your advice and greatly appreciate you helping me. I'm just nervous because I don't want to lose these plants. I had a grow about six months back and I never had any issues like this at all, other than too much N causing the claw with my last plants. and I am trying to do everything pretty similar as I did before . . It was my first grow and I made it all the way to harvest with 6 ounces dry

i just looked, jobe's tomato food is 2-7-4...not the best ratio for young plants, but you gave it so little it shouldn't matter. it looks ok for early flower, i'd look for something more like 1-2-4 for after the stretch.

i don't like soil with chunks of wood in it. i think it does crazy shit to your ph as it decomposes. i think i might give it a couple of gallons of ph'ed water, then a third gallon of 1/2 strength GROW nutes, then just let it dry out and see what happens

 

[Illicitmango]

I've been watering with tap water . Do you think that could be my problem?

 

[Roger A. Shrubber]

depends on whats in your tap water. different cities use different methods, its surprisingly low ppm where i live, and very low chlorine lvls. some people says their cities water is much higher in ppm, and even if you know the ppm, you don't know what it is unless you call them up at the water department and ask them what they add to the water. they'll usually tell you.
the most important things though are ph and ppm. get a meter of some kind for both, if you have very low ppm you may have to add a little cal-mag to your water often. if you have very high ppm it may be worth it to go to the store and fill up jugs at the ro machine, or even buy an ro machine, i don't think they're very expensive for the smaller ones.
most of the time in soil you want to stay pretty close to 6.5 ph, i let it swing up and down a little but not as much as coco.
i really think you just need to feed them. they've surely used up whatever nutes were in the soil by now, and one spoon full of bloom nutes aint gonna cut it. i like something in the area of 5-2-3 for veg and 1-2-5 for flower. different plants and different set ups may demand more or less but i think thats a good rule of thumb to start from.

Wood sucks up the nitrogen in the soil, competing with the plant.
