Two out of four plants are still being very yellow. What could this be?

3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

Yellow leaves from bottom upwards
I have yellowing leaves from the bottom up. It resembles either N deficiency, MG deficiency or both. Growing in soil. PH is between 6.5-6.8. Feeding 1ml/L fish mix and 3ml/L bio-bloom every other watering. I tried adding cal-mag with N at 1ml/L and if anything it's got worse.

Issues after first sledgehammer flush, 4 weeks
Hey guys and gals, on week 4 of this indoor, hydro grow and I just hit this plant 5 days ago with fox farms sledgehammer for its first flush. Before this, the plant was growing very well. Is this due to the flush? Should I flush in tap water before next feed? Thx for the help ^^

Leaf tips yellowing in early flower... Nute issue or normal?
Hi guys, so my LSD-25 is on the second day of flowering. Assuming everything else is perfect, does the soil (Happy Frog) need fertilizer or should I let her be? Organic fertilizer: amazon.com/Down-Earth-Organic-Fertilizer-2-5-0-5-2-5/dp/B000CO7ZYI Thanks for the help!

Feeding
How often am I meant to feed and water my plants. I do water my plants every 3 days and after every three feeds I flush. Concerned as all the bottom leaves in my grow are turning yellow but the tops are okay. I do give them Calmag so I’m not sure what the issue is here.

Lowest leaves turned yellow
After a very hot and sunny day (about 37°C) I noticed that the lowest leaves turned yellow. Is this a sign that I should use more Terra Bloom? If so, how much more should I use?

Leaves losing "color"/turning yellow-ish. (autopot without nutes)
I've been using autopot system wihtout nutrients, plants now went to bloom. Could the smallest of the bunch (NorthenLight left down corner) have some defiency? As others are not "complaining", at least yet. Should purchase nutes that work with my autopot, only biobizz left now.

Rapid yellowing of some leaves
I've noticed strong yellowing of some leaves overnight. It usually happens to the lower leaves, but in my case the whole plant is pretty flat, so there's no real distinction between lower and upper leaves. Is that just flowers taking up nutes from lower leaves or some deficiency?

Week Three slight leaf discoloration
In week three I'm seeing some slight discoloration. Not sure if it is something I should be concerned with. Using COCO, Worm Castings, ReCharge. Watering daily to keep the amendements active. Maybe I'm watering too much? Love to hear your thoughts. Thank you and happy growing.

Light green tops
I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers
