Hey everyone this is my second post on the site. Got 600w MH (25in away) scrog going. 5 gallon pots since 5/16. Fox farm ocean forest soil. 3:1 soil to perlite.

I have only used straight water so far, no nutrients until yesterday. They are about 50 days old. My computer won't let post another pic so I'm going to explain what's going on and post pics right after this one. I noticed the bottom leaves were beginning to yellow and turn brown on the edges. I didn't notice because it's a scrog and I didn't get in far enough to see it until I tucked some branches. Since I have not been feeding I figured they were hungry. I fed them at 1/4 strength. However today I feel it may have gotten a little worse but not 100%. What is throwing me off is that if it were a nutrient burn it would be happening on the new growth up top, not the bottom. Is that correct? My screen is filling out and will be ready to flower this week and need to figure this out first. Please let me know your thoughts. Greatly appreciated

Well I guess they did upload haha so theres 2 pictures that are one plant. 1st and 3rd I believe. It shows upper growth coming in with a light green yellowish color almost dotted. The veins seem to be staying green though. Lack of N? Thanks everyone

They look like they could use more light, how far is the light? Also they looks a little over wet, do you let the soil dry? Definitely needs nutes.

The light is about 24 inches away. Soil is usually dry every other day or every third day. And so your saying that those brownish yellow spots on edges of fan leafs is because lack of nutes? Not a nute burn correct? Thanks for reply man
