White widow leaves hanging downwards and yellowing, first grow

I'm starting to worry about my first grow. It started out fine, very healthy looking green plants.

Now they are a lighter green and some of the leaves on the lower part of the
plant are yellowing and almost drying out. The leaves are also hanging more than ever. The plants have grown for one month now.

Can anyone recognize these symptoms? All input is appreciated!

they look alright just hope the yellowing does'nt get worse. the drooping leaves could mean to cool when the lights are off try and keep a steady temp of 70 degrees when lights are off.

I can't remember when I watered them before taking the pictures. But I give them water whenever the soils feels dry. I usually stick a finger into the soil and if it doesn't feel moist they get about one liter of water split between the ( plants, the ones being the driest getting the most water. I'm a little wary watering them too much since I've read it's better giving them too little water than too much or else there's a possibility of the roots rotting and the plants dying. And sometimes the soil in the middle of the pot is wet while the soil closer to the edge of the pot is dry, so I'm a bit confused as to when I should water them.

The diameter of the smaller pots is about 16 cm (6") while the larger ones are approximately 21 cm (8") in diameter.

You're right, I just use regular tap water. Should I change the pH of the water to anything specific or should I just adjust it so the soil pH is between 6 and 7? Would using a readily available base or acid such as baking soda or citric acid be fine?

Thanks for your help guys!

You can add a little white vinegar or citric acid to bring the pH down; you do not want to use baking soda as that makes pH go up. You don't need a whole lot. Also, either catch rain water or, if you have to use tap water, fill up a container and let it outgas for a day or two before using it on your plants.

I just tested the pH and it says the pH is 6.0. I'm using pH sticks ranging from 2.0 to 9.0. I just poked a hole in the soil and put the stick into it and left it for about a minute. Is this the correct approach? If it is, it seems like the pH isn't the problem...
