First-time grower here. About 50 days into my grow with some Grandaddy Purple autoflower seeds. I have a basic setup, keeping an eye on temp and humidity inside the grow tent. Didn’t mess with nutrients as it was my first grow and just kinda wanted to see how things would run. I had some early yellowing of the edges of the leaves, but after some research I assumed it was either some light burn or nutrient burn. I did flush the soil with water but after that I sort of just let them be. Just being sure to keep them watered with a good temp and humidity. But now that I’ve entered the flowering stage I’m beginning to worry it may get worse and potentially damage everything. I added some images of what I’m talking about, there are multiple leaves with the same coloration going on. Any help would be greatly appreciated, thanks!
Hi, Need to add nutes to soil for flowering, it takes a tonne of energy and materials to make buds and thc. She don’t look very sick just hungry. What ya got for nutrients?
Bare soil (not amended, no added nutes) doesnt have enough to finish good buds. Or good tomatos etc heavy fruit or flowers. Can grow a leafy bush though. If ever suspecting light burn consider the whole plant top to bottom as the lights are closest to the top.
I don’t have any nutrients currently. The only stuff that went in was the hot soil when transplanting to their current pots.
I’m glad to hear that she’s not sick and just maybe hungry. I plan on going out and grabbing a PH meter and maybe some flowering nutrients. Any specifics you recommend?
Ive only used two. Liked em both. Havent used enough to make recommendation.
I havent heard of a bad nutrient brand, results around here… All looks good. Awesome buds everywhere
Welcome to the community Growmie. Agree with @Jaysittinback…she’s hungry. I would suggest Jacks 321 as a nutrient line, super simple, easy and a lot goes a long way with start to finish capabilities. A PH and TDS pen will be needed for mixing nutrients and testing run off. In veg more nitrogen is needed and moving into flower more PK will be needed. When I grew in soil my target PH was 6.5 with PPMs at 900-1000 
Guys, can you also help me with my problem? I haven’t had anyone comment anything yet. Maybe someone can give me some advice as a first-time grower. here’s link: Toxicity or deficiency?
