I'm growing Big Bud. These plants are growing fast, after 4 weeks now they are 11-12 inches. I started giving Fox Farms Grow Big a week ago with a 1/4 dose and then a 1/2 dose. Just watered yesterday with no nutes. But after researching I'm thinking I'm not giving enough because the bottom leaves are yellow. I'm only watering about 3 times a week.
Also the tips of the tops are turning yellow, is this from the light being to close or the start of root bind? Growbox temps are around 76F. The plants are in 1 gallon containers, the lights were 18 inches and I moved them 4 inches further away. Doesn't seem too hot anywhere under the light.
The photos show the symptoms. Any help or diagnoses would be great! thanks.
