I've started a couple of new seeds in rockwool but this time I followed what some people say about adding a diluted amount of nutrients to the water the rockwool is soaking in. So I soaked it in 1 gallon of 5.8ph RO water with Jacks 321 being:
.45g Jacks Hydro
.3g Calcium Nitrate
.15g Epsom Salt
I've transferred the seedling at sprout to a DWC bucket with the same low nutrient ration, however this photo is of a 1 1/2 week from sprout plant is yellowing at the new leaves and just started its 2nd node. I would think a seedling without nutrients could grow maybe 3-4 nodes before starting to yellow.
Is the mix too strong?
Is it something else potentially (nutrient lock out? Mixed Jacks>Salt>Calcium)?
Maybe not enough N?
