Plant seems like it’s dying, potassium or nitrogen deficiency??

Halfway through to the bottom of my plants leaves are dying, I need help diagnosing the issue. I’m growing in coco/perlite indoors. The pH of my nutrient solution is 6.0

are you feeding it any nitrogen?
Not specifically I’m currently giving them FNB @8mL/G and CalMag @4mL/G. I was originally only giving them the FloraTrio but I don’t think my plants liked it.. plus I increased the ppm too.. anywho, how can I directly feed them nitrogen?
 
Mind you guys, those are the bottoms of my plants, the tops are coming in much better ever since switching to the FNB and increasing the ppm from 300 to 800. & I go got to mention these girls are about 4/5 weeks into veg

yours plants just need more feed .. a balanced veg nutrient solution, not just N or K

they are light green and display N deficiency, Magnesium deficiency (last pic) ..

and give them a good flush with your regular nutrient solution next time you water .. the medium looks unbalanced
water with a big drain and waste the runoff, don't keep it
 
FloraNova Bloom can be used from start to finish.......grow is not necessary.

Are you feeding daily to substantial run off?
Yes I feed daily. When I was feeding them twice a day it was making their leaves droopy so I switched to once a day but I do feel like they can definitely go back to twice a day at this point.

When you say unbalanced, can you elaborate?
 
@PeachHazelx Looks like a nitrogen deficiency, you don’t need to water everyday if you’re watering until saturated. A good balanced nutrient would have equal parts N-P-K. You need more nitrogen during veg and early bloom then switch to a higher P-K ratio
 
Okay so no to everyday? Good to know!

Try to practice picking up the pots without watering first to gauge the dry weight, then once your plants drink the water it will be easier to recognize the dry weight vs the saturated weight and when you need to water. For feeding purposes you want to read what the plant is asking for, it’s best to let the plant grow by itself for the first couple of weeks (most decent potting soils have enough nutrients embedded within the soil to sustain this life) then see what it needs in terms of nutes. In your case it looks like you may need to up your nitrogen and add some cal-mag. You may want to flush depending on levels but as an early grower you should just focus on drying out the soil and feeding only ph’d water without nutes for about a week or so (mind you, only water every 3-4 days until you have a healthy thirsty plant) and then picking up again with nutes once you are able to take more accurate measurements. In order to properly dry out the plant you may consider transplanting and letting the new soil soak up the excess moisture in the original medium. This should act as a “flush”

Is this the same in coco tho? I am using coco perlite and was always told not to let them dry out since it’s an inert medium.
