Might have a deficiency, but don't know how

Hi everyone. Newbie here.
I have a 5 week old Sour Diesel and a Critical Sensi Star growing in my indoor veggy garden (mostly peppers). I have all of them in pots with Fox Farm Happy Frog soil and I'm using Jobe's Organics Vegetable & Tomato granular food (2-5-3). I have a 600w HPS if that matters. A couple days ago I noticed some spots on the Diesel leaves, I also noticed my poblano plant wasn't doing the greatest either. The Diesel looks like it has a ?calcium? deficiency even though the fertilizer has 7% calcium, the left poblano leaf looks like a ?nitrogen? problem and the right one I don't know but the tip looks burnt.

Since there is no feeding schedule on the package or Jobe's website I've been using a small handful (maybe a 1/2 cup at most) every two weeks. After seeing these leaves I've Googled how often to use the food and found most people saying once every 8 weeks. If that is the case, then I'm giving them ~4x the amount, but I have deficiencies.

Does anyone out there have any suggestions? Anyone else use this stuff?

Thanks everyone

First thing...wrong npk for vegging you need a higher N and I have and just used Jobes, great top dressing , just go get the right one....and only a 1/4 cup for the 1st 3 feeds, then up to 1/2 cup...sprinkle around the main stalk outwards circle, and gently press into soil and a gooood watering

Water,feed (1/4),water,feed (1/4),water,feed (1/4) ..not watering everyday, just when you need to

Its hard to tell without a full picture of the plant but it looks like a calcium problem. Too much phosphorus can also look like a calcium deficiency...and you are running a lot of phosphorus.

you shouldn't need much extra fert with happy frog. dark green leaves and leaf tip death usually mean over fert. the brown spotting does resemble cal def, however, plants show the same sign sometimes for different reasons and it's easy to get confused. to say there is deficiency when it looks like you're giving enough, then most likely the damage you're seeing is a result of too much rather than not enough. the whole point to buying a soil happy frog is so you don't have to tinker with it as it should have enough fert to last for a while. same thing with FFOF. just because you an add more fert doesn't mean you should. but this is a good lesson. maybe do nothing but water when dry and see how things work out. it's easier to add fert later to save a hungry plant than to remove excess fert from a poisoned plant.

Thanks for the quick response everyone. I think I made a mistake calling it my 'veggy' garden, I mean my vegetable garden which is on a 12/12 light cycle. (I use 5-3-3 Espoma Plant-Tone for vegging)

While this might look like a deficiency, I wouldn't be surprised a bit if it's an abundance issue. On all my other grows I've used the Fox Farm three pack liquid food which was on a similar schedule and had no problems (these Jobe's plants actually seem tiny compared to my Fox Farm plants in the past). I recently took 10 steps backwards financially to go to college so funds are small so that's why I'm using the $10 Jobe's/Espoma rather than the $50 FF. Since I have yet to find an official feeding schedule for these fertilizers I've been comparing apples to oranges and guessing on how often to feed.

Should I flush the plants or just give them straight water?

when you flush, it's only with water, to wash excess nutes out. I'd just water for a while and see what happens. ferting really shouldn't be necessary until much later.

Thanks for the replies everyone. I'll start giving them some RO water and see what happens.
