Yellowing leaves and yesterday curl down leaves after watering
I'm growing in coco. Is 500ml/2 days too short watering? Last growth happened the same with lower leaves (yellowing). It was because of nitrogen deficiency. But EC go to much up if I add more fert. I'm at 5.7 pH and 1.2 EC, 25-26°C and 65% RH now. That's why I use worm humus.

Nute lock-out?
My plants appear to be a yellowish color. I am not sure why. I have tried correcting everything I could think of . Run off pH is consistently 5.8. Ppm/Ec is fine. Light is now at 28in/71cm above canopy only at 70% power. Temperature and humidity stay in great range. I don't know.

Yellowing of leaves during flower
What is causing yellowing of the bottom/backside fan leaves during week 5 of flower? Should I worry about it spreading? Increased bloom nutrients to 3ml/l recently but could have started when feeding 2ml/l. Or is this just leaves yellowing as a part of flowering?

Yellowing Leaves, Red Stems, Brown patches.
pH is correct - run off ph, too. These are 2 out of 4 plants who show these signs. I gave less Flowering Nut in fear of giving too much Nitrogen. Cal/Mag is in use. Is it Phosphorus/Potassium def? I just flushed and gave BioFlores in recommended dosage again. Thoughts?

lower leaves turning yellow and stem turning red
hello I ask you for help for a beginning of yellowing on the lower leaves and the red stem what do you think? I don't know what conclusion to draw from this, the leaves at the top are very green, almost dark green, but those at the bottom are yellow.

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?
Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.

Spots on leaves
One of my girls seems to have some spots on the leaves. She has been like that ever since sprouting. Is it just genetics or is it potentially a disease?

Not Nutrient Burn
Well I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?

Hojas bajas amarillas
Tras un día de sol sin un calor excesivo he detectado hojas amarillas en la parte baja de esta auto mutante (2 plantas de una semilla). La he alimentado con algunos ferilizantes, incluso calmag en una cantidad adecuada para la prevención... ¿Qué podría significar? ¿Como parece?

Yellowing new growth!?
New growth is yellowing is this nitrogen deficiency? And it’s only happening to this strain. Also growth in general has slowed. Temps. Have been getting down to about 66-67F Bc of the cold front that came through.
