If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?
If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine? Humboldts Secret nutes, Glueberry Og Auto, rh48 temp74-76, advice appreciated.

Looking droopy/yellow due to light burn?
Looking like light burn (most intense from the top) and maybe overwatering? I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.

Yellow leaves since 1 week
Hello my friends, More and more yellow leaves since 1 week. I need to be worry? I think it's not a problem of ph because my other plant look healthy. Maybe too much water? I just give her 2 x 0.6 liter per week and fertilizer only 1 times per week. Senescence? Thanks for help

Nitrogen deficiency but why?
My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Newer leaves also turning yellow at the tips. Flush?
Newer leaves also turning yellow at the tips. Started to give the plant Terra Bloom,Sugar Royal, Pure Zym and power roots again after only giving it water for 2 weeks long. Is this a nutrient burn and will a big flush help it out? Doesn't a big flush overwater the plant?

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

Lockout or not enough nutrients ?
Hi grow fam, I’m starting to see some slight discolouration on a couple of leaves. I’m wondering if it’s being nutrient deprived or locked out. I am leaning on the side of caution by using GH’s light feed schedule. No signs of root rot inside the bucket
