Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

Leaves bright green
So I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

Nitrogen toxicity mid-flower
So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

The most common yellow leave will be found on the terminal stage of flower because plant will power up for flower produce rather leave grown. Leaves are most of the time a reservoir of H2O nutrients and minerals. Yellow leaves can apear on you plant at some point of grow?

I don't know why it turned yellow, is this normal? The pH is fine too. I raised the light to prevent burning.

Yellow Colour
Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?

First time grower. Looking for suggestions.
Should I be worried about the slight yellow on the edges of the leafs? They don't looks very healthy. How often and how much should I water during this stage?

As you can see, the first two plants look quite good while the last two leave something to be desired. The leaves on the back left are curling downward and
and yellowish at the tips (in places). What could be the reason? I ordered some epsom salt to try it out (sulphur). I grow in floragard proffesional growmix (grown in lightmix from biobizz) and have so far only “fertilized” with supervit, otherwise only pH-adjusted water. pls hlp

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?
