You do not have a diary so we are guessing based on one photo. It could be a magnesium deficiency.

Clawing / Stunted
Nitrogen toxicity? Day 24, heavy soil and plastic pot, thought overwatering because the soil wasn’t drying out. Put lots of extra drainage holes in it and let dry out for 6 days. Giving plain water today. Will she recover or go to flower in this stunted state?

Small yellow stains
Hello colleagues! Would you kindly help me and tell what these yellow stains may be caused by? I think I could set the ph-level too low, so it may be a deficiency of some nutrients, but the plant seems developing normally.

Is this a deficiency or burn?
I have 2 new, 2 week old seedlings in my grow room and the bottom first set of leaves is yellowing at the tips to like half way up. Their not as green as the new growth.

Yellowing leaves & tips curling down on 14th day. Coco / Autopot / Hesi / Mars Hydro fc-1500
Would gladly use some help with my first grow 🙏 2 main reasons come to mind after googling: 1. I overwatered thinking it's hard to do since I'm using the Air dome. 2. Too intense light. Was checking a lot of growers that actually grow 24/0 and went for it 75% 40cm.

Yellowing Sugar Leaves
Noticed the sugar leaves on bud leaves are also yellow. My understanding is this can have a big effect on final yield?? Flushed the gal but as no amber trichomes yet and want 20%, should keep flushing now on or resume feeding till some amber??? Cheers

Losing colors :'(
I watered only 2L of water without nutrients this week (pot 30 L) You can see it on the diary photos, the plans have lost their colors (yellow). I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion Thanks !

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?

Leaf discoloration. 5 weeks old
I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)
