Yellowing older leaves
Flavio
started grow question 6y ago
Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

Trouble with autoflower
Hey everyone, my seedstocker Critical XXL autoflower sprouted very quickly and had initial signs of fast growth. Since the leaves have become a lot more pale (week 3) to the point I’m worried. The other auto strain I started looks perfect in same conditions

Slight yellowing of fan leaves
Yellowing of leaves on my second grow. Only 1 of 3 plants doing it. Same medium, same light, same watering etc. Only used a general 1/1/1 feed so far and water. Read about nutrient deficiency, over/under watering etc but I'm baffled. No adverse effects otherwise

Northern lights with yellowing leaves
Hey Guys, my NL is starting to have some issues. I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related. I did a small flush 3 days ago and things got worse. What do you guys think?

what is the problem?
The colors of the leaves make me think. I don't give a knock during these weeks of bloom time. Do you think this is a lack of calmag? or this is normal:)?

Yellow tips?
First timer here. What might be causing the small, yellow tips? The leaves sometimes look slightly pale but damn if they don’t look super healthy overall! I’m using minimal nutes thus far. Any insight? Thank you, thank you.

Calmag or not?
I'm thinking this little lady might need calmag as new growth looks a little off colour, any opinions are appreciated my tap water is around 60-65 ppm this is my first time in just Coco + perlite, so should I add calmag to my schedule? Many thanks in advance

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?
