Need help what's wrong with my autos

[Marko]

My autos are between 13 and 16 days old and the leaves on some are yellowing and I need help with diagnosis. I am feeding then 1/2 tsp of grow big fox farm and if they can handel it 2 to 3 tsp next feeding I usually water with food every other time like stated on the food chart . I just really need some help with what's wrong .I even foliage fed with optical calmag .the pics are from about 5 days ago.

I'd lean towards them being over-fed. In general, seedlings don't need to be fed til at least day ten or so. If you've been giving them up to a TBS per feed since day 8-10, that seems like a lot of food for such little ladies. Also, they don't show (to me, at least) any signs of over or under-watering. No droop, no clawing, etc.

Again just my two cents, but I'd bet cutting back the nutes would help quite a bit.

..what soil are they in? Too soon for feeding unless this is a soilless mix, or seedling,... certainly don't go 2-3tsp/gal next time, or you'll fry her! ....cut foliar too, more is not better when this small,....

I'm using promix high porisoty and I'll take your advice on not feeding it any higher.here are a few pics of what two of them look like today .

If you have some suggestions to what's wrong with this plant I would be great full.

Ah, soilless,... feeds are okay, just not that strongly yet, ease it up as they get bigger,.. she looks much better in the new pics! Watch the leaf tips carefully, they will yellow and burn when the feeds are too high,... other plant looks like she needs more food,...

The strain is critical neville haze autos and the newer growth is light green and I was wondering if anyone has had this happen to their plants. I just fed them a few days ago with Fox farm grow big 2 tsp per gallon I'm using promix hp and 5 and 7 gallon smart pots. The pH of my soil is somewhere between 5.8 and 6.5. Iv been using pool strips till my ph meter and ppm pen arrive in mail.

Any ideas what deficiency is going on if any the small undergrowth are light green .may be it's just the strain?
