Nutrient Deficiency

I am thinking that this is a nutrient deficiency. Can anyone please help me out with this? PPM 650 PH 5.8 Rock-wool blocks week 2 of veg. Thanks in advance

Your ppm is pretty high for week 2. you need something on them blocks to keep the light from hitting them and the roots. Hydroton would be a good bet. and it looks to me like a cal/mag issue but what do i know. what nute line are you using ?

I'm thinking nutrient overdose as well.

Are you feeding calmag? Looks mg def. But its burning at the same time. Lower the feed and add about 20% of your total feed as calmag. Could be too much K locking out mg also.

Thanks guys, I am using Botanicare cal mag plus, pure blend pro grow 3-2-4, AquaShield, silica blast, Orca, & Humboldt Prozyme. If 650 is a bit high, what should I be aiming for, I have diluted the res down to 450.
