Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Super Yellow Leaves in Mid/Late Flower
Does this bottom left plant need more nitrogen? The last two waterings we've given it 1.5 ml/liter of Micro. Should we give it more? The other 3 plants of the same strain are much smaller, much darker green, and further ahead in flower. These Blue Dream autos are 51 days old.

Yellowing and dry/brittle leaves
Hello all, I've noticed the leaves are starting to yellow and some are getting quite dry/brittle. Is this a sign of overwatering or perhaps nitrogen deficiency? It is on the same watering schedule as my other plant which looks healthy but obviously has different genetics.

What can I do? Leafs starting to turn yellow. First grower
Yesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Leaves still yellowing
I've been losing leaves to yellowing for awhile now, adjusted my water, feeding it seaweed, gypsum, fox farms big bloom, epsom salts, occasional blackstrap molasses and it is still occurring, is this normal and I'm just worried too much or is there something I'm not doing right?

Nitrogen deficiency or could it be nothing
In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Yellow Leaf on mid flowering stage.
Hello everyone, how is growing? I noticed some leaves turning yellow on the last week, I'm not sure if I overfeed them or if it is some kind of reaction because I put a new fun in the grow. Does anyone have the same kind of situation? Because it happened only in one of the plant

N or P deficiency?
Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

1st plant. Seems stunned and yellowish with black dots tips. Can anyone give a hint?
Hey, guys! How are you doing? This is my first plant. It is 4weeks old, planted on cocó-perlite mix. I find it growing too slow based on other diaries, and it is starting to show these yellow with black dots tips. Anyone can tell me what’s going on?

Yellow discoloration again
I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

Dying leaves
I think it's a nitrogen deficiency causing me to lose some leaves earlier than I hoped, What should I carry on doing from now on? Last watering was 0.5ml/l of Grow, 2ml of bloom and 1ml of CalMag, just recently fixing a calmag deficiency after not having any(ran out).
