KkB, absolutely not an issue mate, plenty of space for all here :smoking:.... single cotyl's are not so uncommon, so are tri-nodal plants,... some correct after the first or second set of true leaves, others in the case of trinodals may keep that pattern all the way,.. those are a hoot! Mono-nodal plants don't seem to fair well if the apical meristem doesn't 'reboot" to normal growth pattern,....
cannabis horticulture is part science, part practical green thumb knowledge! We all know, there's no substitute for experience! If ever you have problems, post up in the Infirmary, ok? Auto's, photo's there's no difference in the approach for germ'ing seeds, and there's more than one perfectly good way to do it,.... You can however, over emphasize the technical aspects and maybe worry too much about specifics,... the basics for germ'ing are proper temps, and RH%,.. domes aren't needed really, unless the RH% is low,... covering them with little to no airflow invites fungal crap to show, and under that dome it's well into the 90's%RH, which isn't optimal either,.... nice warm temps are key in germ'ing, high 70's low 80's, and darkness,...
So, you're growing in coco? That is a fine medium, but tricky,.. that's where some serious research is need first, as it's a unique soilless meduim with several do's and don'ts, unlike peat based soilless,... coco has some odd CEC properties (cation exchange capacity), which makes it a major Ca hog, mg to a lesser extent,... high quality is a must as coco has a lot of native Na and K in it until it's aged, rinsed, and CEC buffered (not pH).... coco will keep the Ca to itself until sated, roots won't be able to uptake it,... depending on your water source and nutes (coco specific), Ca-Mg may be needed every time to water/feed, which in coco, is a lot more like hydro than true soil... in coco you feed every time, never water alone, unless there's an issue, then Ca-Mg is needed regardless,... [HASHTAG]#1[/HASHTAG] problem medium I see here, many folks treat it like true soil and that results in a TARFU situation very time! It's upside is that it breathes better than anything else, holds and releases water very well,... large pots are not necessary, in fact most coco gurus here don't go more than 3gal,... monsters can be had in small pots, but your challenge is to keep them well fed and moist,.. in stand alone pots, you need to be doing drain-to-waste with about 15-20% run-off each time, to keep nute salts from building up,.... monitoring the run-off EC/ppm's is key, as is pH going in and out,...
Are you using HPS lights? How far away was the light? Seedlings want less intense light, as well as moderate temps and RH%,.... consistent even moisture as well,.... coco is devoid of nutes. so feeding should start within a few days weakly at first,....
