Please help me identify this deficiency

Medium: Soil fox farm happy frog
Temp: 81-73 F
Soil ph: 6.8
Humidity: 50-40%
PH of water fed: 6.3-6.5
Light: 400 watt hps
Nutes: Pure Blend Pro Grow,Silica blast, PPM 600 feed nutes every other watering so once a week

These plants are two weeks from seed and have started showing signs of this about 5 days ago now.My initial thought is to feed them some cal mag to see if that helps if you can give any input it would be much appreciated>>>Sorry for the low quality pics but I think you can kind of see whats going on here

yeah I have looked it up a lot the problem is im pretty new to growing and a lot of the symptoms fit so many different deficiencies so I was hoping for someone with more experience to point me in the right direction thank you though

Well since you actually did research to me it looks like a mn deficiency which usually happens when there is a lot of mg in the soil try foliar feeding with a fert with mn in it.

manganese I was just reading that over in my bible right now so would it be a bad idea to feed calmag? The bible says to lower ph and feed chelated micro nutrient formula would that be like the Micro from AN 3 part grow,micro,bloom because I still have 1/2 a liter of that

I would just keep it simple and start by trying a chemical fertilizer with mn in it and see if the resolves the problem there's no use in overloading the plant with a bunch of nutes that it may not need it could cause further problems, and I don't want to be the one to advise you to do that with no personal experience with those specific brands I've only used fox farms.

that's cool I think I will take a trip to my hydro shop and see what they recommend thank you for the good advice...peace

Yeah no problem, if that doesn't fix the problem let me know it could be a few other things.
