Airflow directly connected to nute uptake?

I have four babies in DWC in flowering right now and I noticed something weird happening. The fan I have is pointed at my lights but a few leaves from each of the plants is catching a little wind. The thing is that only those leaves are showing signs of nute lockout. The leaves turn a pale green and get crunchy, sometimes along the edges,or in the middle, or on the tips. Im sure its not nute burn because I keep my ppm around 1000, aslo because no other part of the plant is affected. The only thing is that over the course of the day, my ph will rise from 5.8 to 7.6 so it requires constant attention. Im really good at checking it multiple times a day but the other day I couldnt attend to them and the ph got to 7.6. Over the course of about 4 days, about 7-8 leaves have been showing signs of nute lockout, but only the ones getting directly hit by the fan.

So my question is, is airflow directly connected to nutrient uptake?

I theorized that the excess airflow to those leaves caused elevated levels of production of sugars in the leaves, which in turn calls for more nutrients, which werent available at the time, so it caused the nute-lockout symptoms.
Is this correct or am I just really fucking high? I know all the photosynthesis and ATP and glucose biology shit so no lessons please, Im just wondering if my plants are telling me to increase airflow and nutes in return for a fatter harvest. Anyone experiment with high/low airflow to see the effects? Im talking direct power fan compared to common intake fans.

it sounds like your just dryin out the leaves to much with the air flow being on just a few leaves. i could be wrong tho. try putting a fan that will swing the air flow from 1 side of your veg room to the other., and see what that does.
i have a question for you also... why does your ph swing so much?? thats a crazy swing. how big is your container? i had 6 plants in a 20 gallon tote and the ph would only move from 5.8 to 6.2 over a week. it sounds like youve got something making you work waaay more than you should have to.

Im not sure why it swings so much, it always has done that. I have 4 plants in a 10 gal res. You would think you couldnt dry out the leaves in deep WATER culture...but you never know. I have moved the fan but it was something that was just curious about.

The drying can be a number of things....I had the same shit happen to me and it was due to heat stress and Mg Deficiency, and 7.6 as you know is a danger zone, and with hydro keep it at 5-7ph...Zinc deficiency can look similar... I would sugest flushing your whole system and refill with a quater too halfe strenght nutes for a couple of day to a week.....

How old is you babies? if they are very young 1000ppm could be too strong for emm. Try 600-800ppm...
