Leaf burns

This is a tough situation to call. Your plant looks good in the picture except for the lower leaf yellow tip. What I noticed in your diary was your light DLI in week one is set at 28. That seems a little high starting off, the plant can take it alright but it can cause a little stress on some varieties especially if other things are a little off. Like too much or not enough nitrogen. Variations in VPD. A light burn can look like a deficiency, and vs versa. Trying to make any changes to correct this right now will probably do more damage than good. I’d keep the VPD and PH in check, when you water do it thoroughly, and when you feed, your plant appears to be on a pretty good schedule. Be patient and observe daily, let it grow. Younger plants are pretty sensitive to slight changes. Give it some time.
