Looks a bit like nute burn to me.Though I have seen that same burn when I forgot to water.Did they lay down and you watered them back up?Are you using a strong fert already?Seems like it may be getting past it now since the symptoms have not reached the upper fan leaves so I wouldn't worry too much.

looks to me like the leaves above are cutting the light source, try pruning the dying leaves and giving it more surrounding light, a good idea would be to run clean water through your dirt to remove the un needed nutrients, -if it isnt to do with light...

I have the exact same Problem But mine dont look that ruff. At one point I believed it was bugs eating the tops of my leafs (I saw small Larva style bugs yellow and orangish colour) then the leafs dying slowly under the light. But I only saw the bug on one plant that I had brownish leafs and now most plants have browing leaves. I will post some picture tonight.

I think its a Heat issue. It can get pretty hot in my Cab and Its almost as if I see the leaf satrt Green then slowly look like it fades in colour then after a week it gets brittle and brown.

Maybe its a nute Burn, I feed then a little nutes at 3 weeks old 1/4 strength and watered down from that too. Botaincare Pro Grow. But the top leafs are nice and healthy so I dont think its nutes.

I tested my Ph Runoff water and It sits around 5 - 6 I think that is ok. I use ProMix BX so Its balanced etc.

I think its heat cuz the leafs stand up on the tip edges and I read that if they stand up they are protecing themselfs from Heat. but The very tips of some of my leafs curl down. Not sure what that means yet still searching./

Will post some pictures later. Hope we get this one figured out

Also to Add it looks like I am using the same Lights aas you too. Homedepot Cool Whites. Twisty kind 6500K

Maybe its a by product of cheeper lights. Instead of say T5s or grow shop lights.

Kdspeacial, I check often for bugs. Sometimes the odd tiny fly
will be on the wall but none on the plant or under leaves.
Maybe it is heat, I'm not sure.

Mscaboo, I hope all the info is here if not ask me please.
Except for PH. No clue. I know I should. Any affordable ways???
Thanks!!

I wasn't able to edit my post above so I will do it here.
About the group of 3 pictures...
1- Overall view. Lights positioning and dead leaf pruning done.
2- On the big leaf, is it the beginning of the end for it? See circles.
3- New growth at the base, where older leaves have died in the past.

Thanks everyone for your help!
