Thank you I've been using fox farm nutrients trio just gave them the last feeding 2 days ago now I'm just using water have a Brita filter on my tap works great water is always 7 pH and tds is less than 150

Burning from too much fertilizer would be my diagnosis, as evidenced by the uber green leaves. No need to remove the leaves, but cut back on the feeding a bit, especially nitrogen. Personally, I can see no signs/evidence of a cal/mag deficiency. Cheers, Organoman.

Classic cal mag defiency uop your veg feed very slightly if your using a table this plant also looks slightly overwatered too that maybe contributing but if the lights have just turned on that could be that too. Remember NPK are the most importnant nutrients theres a reason these stand and and its because they are mobile nutrients within the plant in constant use by the plant but there are also 2 or 3 more which are Iron, boron and most important for you Calcium and Magnesium. You must have good water in your area most growers using tap water dont really get alot of these problems :) wish you all the best bro :)
