Help yellow Help pics

Over the past few days getting worse, please look at pics using Old Age Grow 12-6-6 accord to what I have read yellow leaves at the bottom means not enough Nitrogen because new groth takes all the Nitro?? I use 1 oz per gallon of Old Age Grow every other day. Too much? Not Enough?

That's like 30ML per gallon. I would have to say that's pretty high, you are giving them basically 60ML of high nutes per 2 gallons of water. What are the directions on the nutes?

Ummm yeah the instructions say 1 ounce per gallon once per week, however the cool guy at the hydro store says Old Age Grow is pretty cheep stuff, so use it every other day.... Hmmm so you think too much Nitro? I have a book called Marijuana Garden Saver by JC Smith that says yellowing leaves from the bottom of the plant is caused by lack of Nitro. Perhaps my PH is off and blocking the Nitro. I am on weel water and it is a little high 7.5 to 8.0 so I am using a few drops of PH down to get me in the 6.0 to 6.5 range. Perhaps my test strips are a joke... Temps are in the mid ninties. Fogot to mention the plant right next to it is in much better shape and on the same diet. First two plants closest have no yellowing leaves and look pretty good during this veg stage. But


the two further plants have yellow leaves??

too hot
over watered
probably phodphorous deficiency - nitrogen dorsn't generally cause necrosis
in soil you should water at about 7.0(6-7.5 is prob fine)
nit deficiency is usually even and slow
phospherous comes QUICK and less even in my experience

looks hot wet and phos deficient to me

also, if you're giving nutes that often, you should DEFINITELY be watering in 2 stages
give your plant @2/3 of the amount of water you would give it
THEN after waiting 5-10 minutes, give your plant another 2/3 of the amount of water you would normally give it
look at how yellow your runnoff is
that's the salts built up in your soil throwing off your PH and blocking mag/phos/cal uptake and making your plant act all goofy
