Your plant would look like it was starving; starting out with severely yellowing fan leaves. You would then keep trying to feed more and more but nothing seems to help. If ph is out of range the plants root system will not absorb nutrients from the soil; aka nutrient lock out. This doesn't happen quickly. It would be very gradual as each nutrient locks out at a slightly different ph value. Even if the ph were to be thrown off in a soil grow which can happen plain old water is usually the cure. A "droopy" plant btw is almost always from either not enough or way too much moisture in the soil. Keep an eye on the freshest new growth; that will always tell you where your plant is headed. If it's a nice uniform green like your plant exhibits it's all good.
Ph is not something you should ever need to worry about when growing in soil unless you are feeding lots of bottled chelates. Stay with organic materials like worm casting & liquid fish and ph will never be an issue. Bottled nutrients can throw the ph off an organic grow by introducing way too much npk value for the micro life and myco fungi to handle. Anything with an npk value higher than 10 has no business in an organic soil but for let's say a hydroponic medium this is fine because there is no microbial population present to upset.
