Anyone know what is wrong?

Hi, i have a couple of seedlings that seem like they may be having some issue. They are both approximately 14 days from sprout. Used %60 worm castings %40 vermiculite. Lights are 630 watt CMH since it broke the surface with lights at the very top of the 6ft tent. I haven’t fed them anything other than what the worm castings are providing. Anyone know what is wrong?

Thanks for the quick response. I give it a squirt using a turkey baster once every few days or so. The pots seen to get pretty light but it is hard to tell with such a small pot. I think it may be a watering issue or is it possibly a nutrient lockout?

I was thinking about transplanting soon as well. Maybe that would help. I am going to transplant into a mix of approximately %60 pro mix hp %15 worm castings and %25 vermiculite. I found when i grew in pure pro mix hp it got really conpacted and the vermiculite seems to fluff it up a bit.

ewc and vermiculite is not a good mix. they both hold great amounts of water and not enough air. mix ewc with perlite/scorcia/pumice etc. add some coir and/or peat if you like. that should serve you better
Yea i had a feeling it may be too much. I just popped a seedling with a mix of %60 coco and %40 vermiculite. Hope that is a better starting mix as it is already planted. U can actually see it in the pictures. It has been maybe 2 1/2 days above ground so seems small but hopefully it picks up. I will have to look at trying to make a mox like u suggested.

Also i am pretty sire i overwatered the seedling in the coco/vermiculite as it seems to be staying pretty wet and i watered it quite a bit. Gonna let it dry for a couple of days till pretty light than water til runoff again unless u guys suggest otherwise.

now you went the complete opposite haha
like 25-30% ewc would be fine in that coco mix it would get it going and feed it for a while but its ok you can just dissolve some ewc in water and feed with that. got any nutrients? also you need perlite to aerate vermiculite is for water retention.

yeah but in your coco mix you gotta feed with waterings after it shows its first set of true leaves so keep that in mind. other than that yeah wait for it to get light and saturate and wait for it to get light again.

i am a little confused. I thought cannabis seedlings do not need nutrients until approximately 2 weeks in? I did not think of adding castings and think that would have been a good idea. The one problem i have is mypromixhp is full of perlite and seems like it doesn’t drain well (smart pots) and it stays wet and compacts for some reason which i find really weird as people say it is so good. I always have problems with the plants in the promix but last grow used some %60 coco and %40 vermiculite and it grew like crazy and stayed fluffy the whole grow. When i watered the mix fluffed went back down and would fluff again next watering. With promix it drains slow pools at the top for a bit and compacts (but seemed to get better with vermiculite) and same with sunshine mix 4 and i have mo idea what i am doing wrong that would cause these issues. I an definitely not overwatering when i do those plants maybe it is the underwatering?

thats the difference between coco and peat and with vermiculite the actual properties of peat doesnt change but vermiculite soaks up the excess water probably and thats why it feels like its better but peat on its own holds high amounts of water so vermiculite is not needed perlite/pumice/scorcia would be better. as for not feeding the seedlings, ewc is a very gentle fertilizer and it’ll not burn when mixed in soil and it’ll provide a wide range of nutrients when plants need it. coco and perlite mix doesnt have any nutrients so you should feed after first true leaves which in fact takes between 1-2 weeks anyway so yeah it can go without nutes for a couple of weeks but after that you gotta feed. that was my point :)

Seedlings do need nutrients, when they come out of the seed, they can survivor with only water, immediately after the seedling starts growing and expanding its roots in search for water and nutrients.

If you want to grow organically, look up soil mixes. Soil mixes usually have more or less the same components:

40% peat and or leaf mold
20% perlite
15% ewc
25% compost
+ amendments if possible.

Something like that, its not written in stone, you can vary percentages here and there, keeping in mind that you need a good texture of soil (peat/leaf mold + perlite) that allows flow of water and air, nutrients (ewc+compost+amendments) for microorganisms, and microorganisms inputs(ewc+compost).

than you guys very much for the quick response. I just want to clarify that when using peat moss it was promix hp which seems to have a lot of perlite but the soil compacted and caused issues due to not drying out. It would take 7 days to dry out but the top would get dry and crusty. I think it has something to do with my watering or maybe a bad bail but same thing with sunshine mix 4 so i think that would be unlikely. The compacting seemed to get worse when i added gaia green dry amendments to my next grows. When i top dressed it woukd not soak into the medium but float on top and create a rock hard crust. I used their premixed all purpose and power bloom

Here is a picture of my grow but i had been underwatering them (except the seedlings which may also be underwatered) for a while at this point due to being so busy. I also added some worm castings and biochar to this last mix.CC4A4E10-BA91-4384-943E-9A0187CF985E.jpegACE7D14B-F597-4711-B658-2DDED97E5619.jpeg

The back left plant never finished. It is an autoflower but it is still going a month after it shoukd. It doesn’t have mich to harvest from it as it revegged multiple times i believe. It was pure organic at one point but put it on synthetic nutes for a bit than really didn’t take care of it. I am a bad parent. Gonna chop it and maybe make some edibles or something.CE58C8BF-6068-43B1-83B4-9C0DA2C2A7FF.jpeg

mulch my man mulching will prevent most of that crusty tops and when you top dress scratch it in work it in a little bit you can disturb the surface roots a bit its not a big deal it’ll grow back

yea. I think i may need some mulch. I feel like the top drying out quick is causing me problems.

in your opinion, what are some good mulch options for the OP and others interested?

you know whats available to you is fine right? pasteurized hay would be good if you have an active soil fauna with composters like worms or completely synthetic weed covers with pinhole sized holes would work well to. i’ve seen that in the lettuce growing thread. that guy was using it to cover his pure vermiculite trays he uses to germinate lettuce seeds. also there are coir discs but they’re usually a bit thin so 2 of them stacked together would be even better. also there are fabric disc similar to coir ones but havent used them before so cant comment on those.
