PotG & Punch Line -- Mars Hydro FC-E4800

Day 22 of veg since popped thru substrate. Shit - got some issues popping up I think it’s magnesium.. I’m gonna run some Epsom salts thru them with micro only tonight.. it’s been so long since I’ve done a larger from seed grow like this in coco or in general. Maybe I should use a coco specific nute in the future but why spend the extra cash.. I can work it out and they’ll recover within a week or so. Punch Line ones look a little deficient in N too.. Update soon considerable smell for early veg. UPDATE Day 24 now and growth is ramping up.. Did a big flush and feed last night on all my vegging soilless plants.. Runoff was fine - 400-600 PPM, so my assumption is the issues I'm having are certainly from the coco. This is Mother Earth coco/perlite mix I've used for some time now.. I will definitely be doing more thorough rinsing and buffering of this in the future. Ramped up the nutes a bit more, hoping that wont be a mistake. Did a mix of 1ml Armor Si 3ml CaliMagic Dash of Epsom salt to kick up the magnesium even more 7.5ml Micro 6ml Gro 4ml Bloom This was based off GH website new feed charts they have. Fingers crossed they respond positively. Like I've said before, this is the first time I've done from seed in coco in several months - I guess got used to feeding clones or something cuz I'm surprised by these issues. Oh well, I'll get past it and this is another reason to run photoperiod plants - I'm not on a limited timeline and can make sure all the girls are healthy before initiating flower cycle. I'd be shitting my pants if these were autos and having the same issues. Wish me luck ——— - UPDATE- ——— Day 26 Interveinal rusting/spotting stopped progressing within 48 hours of feeds outlined above. We can safely assume it was a magnesium deficiency. Taking feeds down just a lick to the following 1.5mL Armorsi 3mL Cali magic 4ml micro 4ml gro 2ml bloom Pinch of Epsom salts to up magnesium. PH at 5.8-5.9 Growth has become aggressive for sure.. so happy to see these girls doing their thing and having issues sorted for the most part. Topping soon.
