Rootbound recovery time
3 Bruce Banner plants were rootbound for about a week and a half or that's when I started seeing symptoms. I transplanted then into bigger pots yesterday. Will they be okay and if so how long will it take then to get back on track?

Yellow new foliage
From my research it could be phosphorus toxicity, iron deficiency or sulfur deficiency. Or it could be over watering. Or it could be poor drainage. Or it could be light deficiency (I have a 42watt Tled with some led strips until Mars 600 arrives)

Iron deficiency?
I suspect this is an iton deficiency due to excess phosphorus. Opinion? Im using GHE flors trio and added som Gro to make Gro Micro and Bloom in solution at a 1:1:1 ratio. Also added Cal Mend by Dutch Nutrients. Pic are 6 hours apart of new growth.

Lower leaves too pale or yellowing?
I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant. Is this a nutrient/light/watering/lst stress problem if at all? First Grow. Started balcony, moved to tent D23. SF-1000 light, 100% at ~ 55cm from canopy.

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Yellow Colour
Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?

Calcium Def/Wilting or other issue?
So after 24 hours of feeding it CM Plus it doesn’t look any better. I’m hoping there is not another underlying issue. Environment remains the same. Pics are 24 hours apart. Or will it take a few days + before seeing improvements?
