Looks like a deficiency to me. I would expect the tips to be worse with burning. Ph your water if using tap water add some mg.
Good luck grower

Thank you so much , would bottled water be better than tap ? Thanks

Reverse osmosis water could be better but you need to add calmag to it. I use tap water just fine. I need to add mg as I have high ca levels but otherwise it is fine. Bottled spring water and such would be a waste of money and could give you other problems which also could be brand dependant. Distilled water works the same as ro water you need to add calmag.

you have to check your water (bottled or tap) for pH and TDS (especially for hydro). The pH should be in a range 6-7 for the best intake of the nutrients. after the vega you need to feed plant with vega nutrients for 2 more weeks (while the light should be 12/12 (for regulars)). Then flush (as mentioned above already) and flowering nutrient's set (more P and K).

also you can use MgSo4 as a nutrient for the leafs during the vega (1ml/L). But do not use it on late Flowering as it will cause mold.

At 7 weeks, some leaves will naturally begin to turn yellow, If all the surrounding leaves are going yellow at the same time, then you MIGHT have an issue. One leaf, no big deal. I say normal yellowing at 8 weeks. Peace out

If you're using tap water you should just need Epsom salts. You can create more problems with too much Ca if you're not careful. Epson should be available at most home depot type stores and is cheap. It has different names in different languages ie in german it is called Bittersalz. I appy 30% mg at 1g per litre.
