Begining to panic!

[imlovnit24/7]

I bought some short rider fem/autoflower and kaya gold from nirvana. The only auto thats been topped as well as 1 of the kaya's and was given a seed that i sprouted from a cali grower i know(mr.nice crossed with sour grapefruit kush) and they're looking slightly off color and droopy. The topped auto began days ago getting these brown spots and just yesterday half the spotted leaves turned all brown and dropped off.

I'm freaking out and can't recognize what's going wronge. I've been using flowering nutes at 1/4 ratio, alaskan fist fert morbloom(0-10-10) and miracle gro's organic nitrogen(8-0-0) and yet the others are just fine except these 3. I have also been hitting them with neem oil and insecicidle soap once a week for good measure except for the auto's that are budding.

So again i don't know whats going on...Can Anyone Help!?

I don't bribe with rep points but to those that offer constructive critisism and good info are rewarded

ok i've looked up alot of info but nothing definitive as to whats the problem. spider mites, dust mites, lots of mildews, calcium and even phosphorous could be the problem but just too many to tell where to go from here, i'm thinking of cutting them down and starting over cuz they're dying faster than getting better at this point...

I am thinkin maybe a B vitamin deficiancy ? other then that i cant tell good luck.

Hmm brown spots are usually a sign of a deficiency like p or k and yellow leaves are usually a sign of N deficiency. You may want to cut back on the flowering fert for the younglings if you are using it on them. I would use a weaker fert like fox farm big grow or something else and maybe even givem a good flush. Some of those younger ones maybe be a lil young to start ferting too. Also, what kind of soil are you using? You should wait for more feedback though as I can't be completely sure.

 

[soul11223]

how often do you feed them?

 

[tigercat73]

either not enough pottasium or magnesium . give them a little of both and they will be ok. a little bit of epsom salt should give them what they need. dont use too much though. a few of mine done the same and it pulled them right out.

I would flush them first of all - use 3 times the volume of water vs soil. Then I would stop with the neem oil and insecticide soap unless you do actually have a pest problem. Inspect the leaves with a mag glass to make sure.

Goodluck

Thanks everyone for the feedback. Though i now realize i forgot some info in my 1st post...

When i give nutes i give'm B1 also at 1/4 ratio

I haven't given the little 1's any nutes not that young at least. Sadly the mr.n/sgk died. I have flushed them twice now

how often do you feed them?

Every 4th watering and all nutes at 1/4 ratio

May she rest in peace!!

I'd say you are probably locked out

First things first, what's the ph

 

[imlovnit24/7]

ph is at 6.4

 

[imlovnit24/7]

From i've determined from all of your help to switch up the nutes to a milder veging mix i have a small bottle of organicare you can see in the pic along with B1 at 1/4 ratio all mixed in a bottle of Frys Distilled store brand water to be as neutral as possible. I tested my horrible AZ water 3 times and came up with an average of 7.3, tho 1 of the tests came out at 7.4 and i got worried about nute lockout( THANKS LBH ) only after testing the water i tested the soil and it was 7. The soil was just reciently 6.4. Since feeding them whith the distilled h2o the ph was at 6.8, still not low enough tho...

Anyone know what cheap around the house materials i can use(vinegar maybe...?) to correct this and possibly how much to use, sadly all i have is ph plus water tester; not for acidic testing.

I'm quite broke right now for the ph adjuster from my local hydro shop
