Week 3 of flowering and my plants have yellow droo...

I think you gave too much water. Stop watering until it getting better

. Calmag is your friend through all of flower too up to at least week 5 or 6 depending on length of flower. Your leaves arent showing def but lacking nitro. I have a feeling your watering too much or a lockout is starting to rear its ugly head. Flush for a week or use a empty chelate(final flush) then ease into a more balanced npk approach and make sure your adding your calmag. hope this helps peace DG

I'm thinking you are giving them too much nitrogen for this stage... the fish emulsion is probably to blame. I would flush them out and then, when you resume the nute, make the first feeding 1/2 strength of the morrbloom and 1/4 strength fish emulsion... going forward, I would cut your fish emulsion in half - they're still going to need SOME nitrogen but not as much as you're giving them! Good luck!

Yes this is 100% overwatering!!! Let the soil dry out completely. She doesn't drink anything yet because her roots are sofucating because of the lack of oxygen. There is a great trick to make sure that you do not overwater again. Just give 50% of the pot water and leave the other 50% dry. When the wet side is almost completely dry then you give the other 50% of your pot water. This way you make sure that your roots always have acces to water with nutrients on 1 side and oxygen on the other side. Happy Growing! 😋

you are essentially soilless (5% soil isn't going to have any carryover nutes from amendments at this stage) i'd treat it like one... when you do irigate, make sure you get 10-15% runoff... this will maintain concentration in substrate. choose to irrigate based on how heavy the pot is... the safest is a full dry back where it gets very light, but avoid plant wilting of course. Frequent irrigations are more complicated.. must have enough perlite mixed in so that you aren't drowning the roots and causing o2 deprevation (results in drooping). so you almost undersize the pot and high drainage properties.. almost requires frequent irrigation.. but it's more "ondemand" so it will have best resutls.. 2-3x per day.. get at least 25-33% loss of weight before repeating. Anyway, keep it simple until you get your fertiizer mix right. you'll want a 650-750 ppm mix... use manic botanix online ppm calculator and the guaranteed analysis labels on you products.. check out my ppm breakdown for a ballpak idea of how much NPKCaMg and S you need per irrigation.... every irrigation should be fertilizing at this concentration... 10% runoff maintains it... this will be akin to teh most fertile soils in the world.. can't go wrong. if you still want to treat it like soil, could feed 2x that but then alternate water-only irrigation between. runoff should occur just to ensure the pot is saturated with no dry pockets in this method.
