have you checked your ph? I just ran into a very similar problem because of my water being so hard causing a nitrogen lockout. never underestimate whats in your water, there could be alot of bad shit in there

nitrogen deficiency as stated...

the cause is always for you to figure out. chances are it isn't high salinity as K is usually the first deficiency symptom with that. You probably just need to feed more, that's the usual one.

check your waters ph every time you water them, if the ph is too high or too low you will get nute lockout QUICK. I had to go out and get a RO system because my cities water is so full of BAD shit.

ok i switched to my ferts for flowering the npk are 9-59-8..i know the ph is high 59! it says to feed teaspoon/a gallon water so i strted out at half of HALF a teaspoon then increaesd it a tad the next feeding. due to the high ph im worried it to much. so i go easy with it..i water/feed every 3-4 days. when dry enough should i back off the ferts giver water? increase them? or increase just N???

actually when the leaf is still green in the veins its usually iron, zinc or mag. i would add some cal/mag with ph water.

wait did you just say 9:59:8? thats alot of phosphorus, what nutrient is that?

...well, I'm goin to say that a good place to start would be to add some rapid release dolomite lime, 1 tbls per gallon of soil as a top dressing and water in as normal. If your ph is too low it will fight to keep it "in range" and also provide your ladies with cal./mag.

When a deficiency starts from the bottom up this always signifies a nutrient that the plant can move quickly. iron, zinc or mag would give different symptoms and not start from the bottom up. even though P will lock out iron, the symptoms of that would look far worse than this simple N deficiency... imo.

Nitrogen deficiency always starts from the bottom up... looks exactly like a sulphur deficiency only a sulphur deficiency starts at the top because it is a slow moving nutrient.


I'd say just to feed more... the plant needs more N. Either get some N or increase the concentrations of the nutes you're using now.

...your plants are yellowish, imo, that's bad pH....too acidic.

...I'd flush, then add the dolomite lime as I mentioned. View the link I sent you above, go view the pH tab to see more pics of similar plants.

like said its most likely a nitrogen issue, i grabbed some nutes with high nitrogen ratio and used 2 or 3 times.

i would recomend stackin the plants up on a nitro boost in veg next time

If you feed lots of N then a slightly acidic pH wouldn't matter. with enough nitrogen in there the plant could find enough to survive at just pH 4.5...

I think soil growers are far too anal about pH, particularly when growing with the best pH buffer of all as your medium.
