Over watering can it be saved

It should be impossible to overwater when the medium is constituted properly. As long as you don't water too frequently, such a thing should be impossible to happen. This medium clearly needs more drainage amendment (see below). A size appropriate pot would help too... big pot / tiny plant is recipe for problems. Water can stagnate in a soil, too, just as it will in a bucket... you don't want the pot staying soaking wet for a long period of time... rate of plant drinking should match pot size. So, it got above the soil then zero vertical growth? May be too much light early on too. Though, i'm not even sure if i see a growth tip in there... which would mean a very significant delay if sprouted without one or burned off by the excess water/fertilier exposure as it sprouted. if you need more plants, definitely sow more seed. So, add more drainage amendments in future. it won't ruin this grow, but you'll greatly benefit from it and so will the plant. A heavy soil should be 50% perlite or similar -- not too chunky. I prefer vermiculite, but each to their own on that. Something lighter, like coco, only need 33% perlite per volume. Both average out to a similar gas:water mixture, which is the goal for a healthy root zone. in america, #2 perlite and coarse vermiculate are great sizes... this stuff can vary by manufacturar and region, so take it as a grain of a salt... again, not too chunky, but also not sandy (medium vermiculite is often quite fine, for example). Anything resemblign big ol chunks of wood is less than ideal. Do that and you cannot "overwater" unless you sit there for 15minutes running water through it, lol. Roots will grow beter; plant will grow better -- and with more consistent results..
