It looks hungry man, like a N deficiency judging at the yellow and extra crispy leafs at the bottom. Suggest upping your dosages if you arent using 50-100% of the recommended

Or with biobizz feed at 50% strength every feed all the way through, no need to water to much runoff either

So, my girl now is 11 days old, while i was looking at here i noticed that the tips of the second pair of true leaves is soightly yellow/brownish colored, im worried for my plant. Could it be a wind burn ? I have a ventilator in my tent which was blowing at here. I moved it now.

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Leaves turning yellow with brown patches
I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Hey, on my biggest plant, the leaves are starting to turn yellow from the outside and getting brown spots. Is that a sign of over-fertilization? All the other plants don't have this. Or is it too little?
