Over fed?

looks like it needs N fo sure... red petioles (leaf stem) can be caused by intense led light but also could be a sign of slightly low P, too. A red streak in stem (branches / trunk - apical meristem) is potentially related to low S. ensure pH is fine.. and assumes you aren't providing some very high EC that is causing lockout -- based on pictures it doesn't seem either is the case, but you should not assume something that can be accurately measured/calculated. anyway, if it were the case you'd see a plethora of symptoms normally caused by numerous necessary molecules' concentration being too high/low and that blocks out several others from being used inside the plant, hence a smorgasborg of symptoms results
