Need some advise.

Hey all! Lot's of great articles and posts. Thanks for it all.
However, I could use some advise with what I'm doing. I have some yellowing leaves. Yes it may be (N) deficiency, or over watering, but since I'm new, I need some experienced eyes.

Thanks in advance.

Setup as it stands:

Seedlings

PH: 5.5
PPM: 1040
Temp: 82
Soil: Organic hydroponic medium (Coco Fiber, perlite, etc)
Water: No RO, using Cristal Natural Spring Water
Nutes: Grow 6-4-3
Light: 600w sodium
Light Period: 24hrs
Over all time: day 20

Just transplanted yesterday to pots in pics. Roots looked good, white, long. When I popped out the plants from their smaller cups, the medium was not mud but definitely well moist. After, transplant, watered new medium a bit but no much thinking the plant medium was well moist and perhaps wait for it to dry-up a bit (just my thought). Pics are 12 hours after transplant. Note: Plants looked the same color and stature before trans. I water with nutes every ±3 days.

That is the gist of it. See pics. Thnx again!

almost looks like a zinc deficiency to me, but those plants are pretty young to be showing zinc def

Looks like a nitrogen deficiency. more than likely that is the case, and maybe you should ease on the nutrients. imo the pH level is too low and i'd aim for a 6-6.5 level. you could have a zinc/iron deficiency as well but i don't think this is the case.

PH is definitely too low - and probably locking out nitrogen. get some dolomite lime, and add 1 tsp per gallon of water, for watering. Soil should test closer to 6.5 - 7. Also test your water PH.

Hey guys thanks for the response. So it seems as if we are looking at a PH problem and (N) def because of it. Well, are there any household solutions that I can do cause I live in Costa Rica and finding dolomite would be highly unlikely. Had to Import the gear I have. Should I do a watering without nutes at a PH of 6.5 or 7 in day or so to kinda flush? I'm open to suggestions, but I only have dental floss and couple used q-tips to work with.

Thank you!
