Hi, since i have tried once the rockwool method i never fail a germination. I suggest you to try! The only thing to pay attention whit this method is to not over water the rockwoll, that absorb a lot of water, personally, i sink the rockwoll in water than i squeeze It ti remove the excess. I big pro of this method is that after the germination you can transfer the rockwool whitout any stress for the plant wherever you want, soil, coco, hydro or even on a cat etc... Hope you the best for tour project!

Organoman - just for the record, the pot size you mentioned, 4 inches by 5 inches, is what I consider a tiny pot. Im pretty sure the ones I use for my jiffy pellets to go into are 6 inches by 8 inches, Or I use the next size down to sow seed directly. .. but agree- decent sized pots are a must. get lots in diff sized and shapes too and see what works best for you. I had access to landscaping waste so I have dozens of diff sized pots. For the last few years im trying to figure out if im insane or if square pots VS round pots with same volume seems to be growing better seedlings... at least in small pots its so far working out that way, but need more data to confirm this. Anyone else finding this to be true??

Seeds prepped in water is most sure fire way I have obtained a high germination rate. It is the oldest and simplest way with great results. Paper towel method takes way too long. Too much handling of sprout. Chances of contamination. I have noticed lighter color seeds tend not to sprout at all.

Yeah it maybe abit to do with running organic nutes, sometimes you can get a delayed onset of effects from amendments or teas and compensate with more nutes and slowly but surely push yourself towards problems by default. Honestly i wouldnt add more nutes just run it water only to 6.3-6.8 ph and let it flush & fix it self

Ph 6.0 try

Calcium Mangel und daraus bedingt ein Rattenschwanz von Mängeln. Dein PH ist zu hoch und das vermutlich schon über längere Zeit. Versuch bitte den Drain auf 6-6,2 zu bringen und warte ein paar Tage. Auf keinen Fall mehr Dünger verwenden; dies würde Dein Problem nur vertiefen. Viel Glück!
