It is important to know that the roots of the plants are not only made for water and food take but also for breathing thus the presence of an excess of too much may lead to oxygen deprivation and would cause the following symptoms:

Bleaching or yellowing

This can happen especially to young plants if they are heavily overwatered. They may appear bleached or yellowish and it occurs starting from the roots which have access to the nutrients coming from the soil. This may also happen because the pH of the soil is no longer ideal for the plant. This symptom may be similar if the plant is suffering from light stress so to make sure try to adjust the grow lights and if the symptoms persist then it could be caused by over water. This happens because can no longer move water and nutrients properly thus the roots and the leaves turn yellowish.

Edges of the leaves turn brown

Looking closely, if the plant is suffering from overwatering, you can see brown patches or burn to the edges of the leaves. Sometimes they may look like brown spots at the edges of the leaves. This is often related to problems that occur on the roots of the plant which is caused by overwatering.

Brown spots

If the plant is overwatered, you will be able to observe small brown spots that appear on most of its leaves. Most of the time it is confused with nutrient deficiency. Brown spots can also be an indicator that your plants lack nutrients such as phosphorus, iron, copper, potassium. The loss of nutrients can be caused or triggered by overwatering. Too much water may flush the needed nutrients from the soil that is why the plant is not getting any. 

Leaves curling up

This symptom also appears when the plant is overwatered and have problems with the roots. This will actually appear a day after the plant has been heavily watered.

Curling down or cupping
