Unknown strain

Could be a lack/lockout of iron as well and + for sulphur. Rock dust is awesome for a much of micronutrients. Apparently, basalt is one of the best. Gypsum has a great amount of sulfur and calcium which always seems to be a bottleneck

also yellow sticky traps get hung not laid. they are just trapping bits of substrate laying down. popsicle stick or something and get them up.

coco coir and peatmoss are normally void of nutrients. I think BioBuzz amends its mix so it has a light feeding for a week or so but you should be feeding it. Needs to be a complete well rounded PH balanced feed. As for identifying the strain go look in your old emails for a receipt of purchase and it is likely that strain. If you bought more then one then its likely one of them. Good Luck!

Npk c mg s are the big 6, which make up 99% of all nutrients ever needed in its lifetime. At such a early stage in life, not much to really choose from. Good call from asnoriu with the nod to sulphur. I know it's not nitrogen or potassium the regular culprits with coco. I'd 2nd sulphur.

If its the yellow color your worried about. i think that's just the new grpth that hasn't gotten its full color yet, but looks like there is plenty of nitrogen from the looks of you bottom leaf

lack of micronutrions, you have to start feeding her, coco is empty, you should go with soil if you wanted to feed rare and less ... think its sulphur ...
