It's a pH flux. Need to drop your pH more when watering. Bit of Calcium won't hurt her either.

Hi there! Check your pH and make sure you don't have any lockouts or anything. That yellowing starting from the tips looks like a Potassium (K) Deficiency but those curling leaves and darker green says you might have something else too.

Yellow tips on top leaves only
First i thought it was lightburn, but i raised my lights 2 times in the last week and no change. Does anyone know what my plant is trying to tell me? I use a growmix and just started to feed her for flower so maybe a shortage of some nutrient or still to much N in the soil?

Yellow tipped top growth
My plant has had these yellow tips for a few weeks now. Seems to only be affecting the top leaves and doesnt seem to spread any further than the tips. 3 weeks into flower and her buds aren't fattening like my others. I added more P. Any ideas? She has plenty of micros...

Massive series of problem, might be killing her
This plant is giving me a hell of a job :( I'm trying to fix problems each watering but it seems that I present new ones when I do so, I'm feeding about 2.5l each time ph around 6-6.5 and I've tested runoff coming at 6.5. What are this series of problems? No exhaust yet, rh 40/75

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers

Light stress or Nute Problem??
Would this be a light stress problem or a nutrient problem? Seems to be only the ones on the top so I'm guessing lights but want to be sure.

What do you do if your run off ph is hi6.9? I've started using bloom nutes so it's going in at 6.0-6.2. Will that be ok or do I need to flush with ph water down?
