Does this look normal doc?

Hi guys,
So learning from my last grow using miracle grow soil, I purchased some promix herb&veg soil.

Im growing a sativa and and indica, both from feminized seeds under led and fluo for my veg period on a 6/18 hour light schedule.

Temps stay around 23-24c and 45-50 RH.
Im not feeding anything, just watering when the soil dries up about an inch from the top.

I know its normal for the first leaves to yellow and die but im noticing that some of the more mature leaves are getting yellow and crispy (see pics)

Does this look normal? These are almost a month old btw.
( I turned off the leds inthe pics, only lit with the fluos. Also im starting to train them, so thats why they are crooked.)

How high is that light?

They are all rigged about 6 inches above the top of the plants.

It looks like you are over watering, you killed the root hairs , there is speed bumps on your leaves.

I suspect it's time for a little fertilizer. a small amount and see what happens.
speed bumps? eh?

Im not sure its over watering. It drains well and as I mentioned I wait until the top inch of soil is dry before watering.

I was hoping that I didn't have to feed for a while as I had quite the nightmare with that mg soil.

What kind of feed would you suggest?

It just dawned on me, I haven't been watering with ph'd water. So I measured my water and it was slightly over neutral. I just clipped off the yellowing leaves and gave them a dose of 6.2ish water. Lets hope it was just a little nute lockout, i really dont want to have to feed so early, especially with this higher end soil.

Ill post back my findings!

dynagrow 7-9-5. for a soil grow, just one quarter teaspoon in a gallon of water. don't bother ph'ing the water.

So I just wanted to update this as it could help some. I decided not to feed and just watered with 6ph water. Also transplanted gradually as they grew. They now are looking good.

Much better (now that they're out of those damn milk boxes).

Have fun
