A Serious Problem,,,,Need serious assistance

Ok, I hate asking but I have a problem that is growing out of control. About 10 days ago I was told it was a N problem and I also had thought so.....I gave em a good shot of high N guano but no success. All my lower leaves yellow and eventually brown out and die. I am not flowering but will be soon. The tips of all my leaves yellow, brown, then die. Also my full green leaves have a uniform blue tint to them but it looks wierd.
I have been vegging for 45 days and both plants have been topped. The single plant is in same soil and conditions but is A OK. I have been googling myself crazy. I dont know what to guess it is now because I think everythings wrong right now.

400w MH
Guano only nutes plus soil nutes.
MG Organic Only has worm castings in it.
Bagseed
79-85 degrees
Ok RH

Thx for any assistance.....SBS +Rep

my friend is having the same problem but he is growing in hydro and he bought another light and placed it along each side and it seems to be working for him dont know how much it will help but it cant hurt

Neutrel distilled water at 7....

How do you know the water is neutral and is a perfect 7.0? Do you have an ACCURATE tester and do you test every watering? Freshly distilled water should have a pH of 7.0. However, interaction with the atmosphere during bottling, shipping and then sitting on a store shelf allows carbon dioxide to dissolve into it, forming carbonic acid. As a result, agitating the water or allowing it to sit for a while will leave you with an aqueous solution that drifts down in pH. Because there are no natural buffers in distilled water, the pH can go down as low as 5.0. Nitrogen gets locked out under 5.5. so it looks to me like your soil pH is low. I would foliar feed with some fish fert like Neptune's Harvest or a SERIOUSLY diluted chemical fert like FF to get them some -N- and double check your pH and runoff...

who ever thought a bunch of pot smokers could be scientist mmmuuuuuuaaahhhhhhh

I do a reading every water yes... Also I feed with 7 but my soil reads almost 8 24 hours later.

Anything out of the range of 6-7 can lockout nitrogen. Your soils ph is at 8 you said. That's a bit high, and can definitely lockout the N. Flush it with some of your distilled water. I'd recommend getting it down to around 6.7 and using that, then see how the plants respond. They don't look too bad though man. Way to stay on top of things.

I tried the flush, wait and refert idea and it got worse. I cut the yellow leaves.

Its def ph problem feed at 5.8 to 6 add some not much less than a handfull of powdered lime by applying to top of soil then water that will lower the ph in the soil in the future mix a small handfull of lime with your soil and keep water between 5.8 and no more tha 6.8 with 6 being ideal..pm me if you need more help...peace redlrg

Hey bro flush the soil with the bit of lime and dont add xtra feed,it sounds like there is plenty of feed in the soil already..your overfeeding and getting continious nute lock out..flush and just water at ph of 6 and dont cut the leaves anymore that will cause the browning to quicken...peace redleg

get some dolomite lime, mix 1Tbsp with 1 gallon of water and then give it 1/4 str veg nutes afterward.

ok now I got leaves yellowing and almost all my leaf tips are dying and whole leaves curling under and twisting. Its looking fucked up. I havnt fed in 1 week and my soil read 7 last night after feeding.

Can we get some new pics to see if it is the same issue or a different one?? My guess would be the later, but need pics.

Ok, this is not a big deal at all man. when plants mature then usually kill off the bottom old couple of leaves to focus its energy on the rest of the new foliage. "Serious Problem" i think not. i'd chill out and wait and see if the problem progresses, but i think your ok for now.

no this is affecting my whole plant. I am having issues with internet and cant post pics yet. Now their way worse and all my leaves are twisting and folding under. Turning yellow and dying. It sucks cause my best plant is a male I think and the worst one is a female Im sure.
