Hi guys/girls I am currently into day 26 of veg of my first ever grow. The strain is supposedly Lemon Haze the plant is being grown under 150W HPS, grown in soil in a 3/4 gallon container on a 18/6 light cycle. I only fed the plant 1/4 strength nutes for the second week then moved onto full strength 4 days ago. The past 12 days I have noticed that some of my leaves are curling inward on the leaf edges, this issue is really troubling me. (I really don't think this problem is caused by nutes but I might be completely wrong lol) I have been reading for the past 4 days trying to suss out this problem but to no avail. I am hoping an expert grower could take a look at my pictures below and come up with some sort of help/guidance/info to help me with this matter as it is really bothering me and I don't want all my efforts go to waste, I have seen a lot of awesome advice from members of this forum and peoples problem have been solved so im hoping you can do the same to me. I understand I am a new grower and have a lot to learn but I guess I have to start somewhere, I never normally ask for help on things, but this time I really need it. Please can you take 5mins to have a look at these pictures and see if you can find the solution to this problem. If I have missed anything out of my description please inform me and I will sort it out. All help will be treated as positive. Thank You in advance. Much appreciated.
