HELP! New grower, need some help.

Hey guys, first post and also first time grower. In need of some help here.

The setup:
2xP1000 Viparspectra (22 inches above plants canopy)
Vivosun 6" exhaust (vented to the outside of the garage)
Fox Farms Happy Frog soil
3 Gal pots
2x hurricane 6" fans
homemade 4x2 grow box (2x 14x6 intake vents at the bottom)
plants are 4 weeks old (roughly)

I have the Fox Farm trio nutrients mix, but have only watered with the Big Bloom mixed with Cal-mag once (1 1/2 tsp cal-mag with 1tsp FF Big Bloom in 1 gallon of water pH'd at 6.3) the rest of the grow I have only used distilled water also pH'd at 6.3-6.5. Recently I've noticed the lower leaves tips turning brown and rolling backwards. Yesterday the lower leaves started turning yellow/brown. I'm guessing it's a deficiency of some sort but looking for some help identifying the deficiency and how to go about correcting it. The grow box stays around 77-79 degrees and around 50-55% RH. It seems like all growth has slowed substantially if any at all the past week. Any help would be appreciated. Thanks in advance.

If you've been using distilled water and no nutes, your plant has been living on whatever nutes were in the soil. Looks like those nutes are done and your plants are nute starved. I've read that distilled water will actually suck nutrients out of the soil and needs a lot of extras.
I'm thinking you need to get some veg nutes into your plants and plan on extra vegging time to get your plant some recovery. What is yellow is done, but what is green is still growing. Keep your pH above 6.5 and keep up with the CalMag.
Are your seeds auto, fem, or regular?
 
Agree with GB. The only difference I have is I am good with a pH of 6-6.5 in soil (although I don’t always watch it closely given my outdoor pots are quite large and have a soil/coco mix). In particular I agree on questioning the use of distilled water unless something is wrong with your regular tap water. Regular water has necessary trace elements not found in distilled water that may not be in your average bottle of nutes.

In short, if your plants are in pots they will eventually use up the nutes in the soil. Once this happens you will need to add nutes every few waterings. You have likely passed that point so give them a feed and see what happens.
 
Wow I never even thought about that, and they are regular seeds. I'm really just experimenting with this grow and trying to learn all that I can. I'd like to get some harvest off of this but I'm honestly not expecting anything crazy. Thank you so much, I'll definitely be giving this a try as my feeding day is tomorrow. I'll add the big grow in with the big bloom and cal-mag this feeding and continue to watch the new growth. Thanks again.
 
I actually pH'd my tap water and it's showing 7.1, and a PPM of 071. Would that be sufficient enough and just pH it down to around 6.5 or so? Very informative, like I mentioned this is my first ever grow and I'm wanting to learn as much as possible. Thank you for the info.
 
What about your evolution from seed to now? Did you sprout your seed before going to Happy Frog? Solo cup? Block?
Photos and bagseed are great to start with because you really don't know what you'll get Tofasgt .
Something I understand about plants going male is an amount of stress it goes through. No clue which stress. Don't be surprised if you wind up with balls. Your plants are stressing.
 
Since your pots are relatively small and you are under lights I personally would continue to lower my pH to 6-6.5 but I don’t want to completely disagree with GB in case his setup is closer to yours and therefore his experience more relevant. I would start watering them with tap water and feeding them nutes every second or third watering (although I don’t know anything about the FF nutes). When I am outside in large pots (30gallon) with a large portion of it being soil I worry a lot less about the pH and don’t always change it from the tap water level (mine is similar in pH to yours although with a higher ppm). Indoor in all coco I keep my pH at 5-6.
 
DeadlyFruit thanks for the info man, can you explain to me how different pH works in different environments? Like the pot size relative to pH like you were saying? Thanks again and I am going to start watering with the tap water now.
 
Hey Gingerbeard I did start them out in a solo cup although it was with regular dirt from the farm, lol. I didn't have the happy frog up until about 2 weeks ago. They started out in the solo cup for around 2 weeks, then I transplanted them into 1 gal pot also with regular soil for around a week or so then I got the happy frog soil in and went ahead and potted them in the 3gal with the happy frog. They've been in the happy frog soil for around 2 weeks now. And I definitely understand the plants are stressing and if they do go male (although a disappointment) I won't be to upset. This is really just a learning experience for me. Lol
 
Yeah it's been in there 2 weeks, I fed them last night (3ml cal-mag, 2.5ml grow big, and 5ml big bloom) I did a PPM when I did a pH, the PPM was 410, pH was 6.3. I watered them and then tested the run off and got a PPM of 3600 and a pH of 6.1. Does that sound right?
 
No idea about PPM. pH is as technical as I get.
Putting full nutes in might not be great since you are going from nothing to a whole bunch. But it might also be the right trick.
I would personally remove everything that is yellowed and watch what happens to the remaining green.
Have you taken a look at the GWE website? Looking up one thing can lead to a hundred other things you never thought of.

I've went through it several times, everytime I think I know what it is, I see another picture that looks like what's going on and I end up more confused. Lol
I first thought it was maybe heat stress, then I seen one that made me think magnesium, then I seen another that made me think potassium. And that's when I posted in here so maybe someone who's more knowledgeable with going and deficiencies could point me in the right direction.
 
It may or may not be possible you may or may not have deficiencies or burns in none, some, or all of your nutrients. It's going to depend on what's going on in your soil.
At this point, treat your plants as if they were on track for 12" colas.
 
Follow suggestions by manufacturers on what and how much to use, when. Water when dry. Use decent lighting. Play sweet, sweet love music.
Keep growing like none of this ever happened except for a lesson learned.
 
Hell I can do that. Lol
I would like to know what has caused this and exactly what it is though, that way I can avoid it in the future or know what it is early and how to treat it early on.
 
I'm pretty confident your distilled water was the issue. Use dechlorinated (leave it out overnight) tap water or vending machine water.
I say tap water with a caveat. Some areas have lousy water. I spent a night at a buddy's place in MO. It was sulfur laden well water. Flint, Michigan. The only ways to tell if it's good is to use it and go for broke or send it to a local university or other local agency. Or, check online.
