Nitrogen toxicity?
RallyAutos
started grow question 6y ago
Are these dying leaves a result of the nitrogen toxicity or something else? Thanks for all your help!

Could be really bad light stress... My guess would be that a high PK nute has locked out calmag and other micronutrients. If you're using a booster, roll it back a bit. As always, check your pH and EC going in and coming out.

I had this before and although not entirely sure I put it down to a pk overdose. N Overdose looks very different - dark green claws.

Need help diagnosing leaf loss issues with the G13 Haze strain (problem has been over 5 weeks now). The one in the smallest pot (7L) has lost a majority of its leaves. The leaves start yellowing and turning brown then crispy. They have white speckles on them like salt.

Defoliation during flowering and overall plant health
Should I proceed with defoliating this plant on day 28 of flowering? I am always a bit reluctant to doing this as I think it stresses the plant a bit too much when it is supposed to be producing flowers, but I would like to hear from you guys.

What are these tiny white dots from?
Do you think I have spider mites? I don’t think it’s moldy mildew. I have no idea where I could have gotten them from though.

Water flush ratio for nitrogen toxicity?
What is the rule of thumb on flushing ? I flushed 3 gallons of water on Day 17 and 18. Today, (day 19), I flushed w/ 5 gallons since the symptoms of nitrogen toxicity seemed only to be getting worse. Hoping that at least stops the progression of leaf clawing...

Trying to fix my plant after faulty pH meter...
Hey guys what do I think I should do.. so I had a pH problem and first I tried to fix my old one but it still didn't work so I might have given her a messed up ph again. So now I got a completely new one. What should I do? Give the girl a flush or some nutes to fix this?

Bound and wrinkly leaves
Some bottom leaves are wrinkly and where bound to eachother. These are new growths that grow from first 4 leaves. I'm having hard time googling the issue. What could cause this and should I be concerned? Last picture is before I split them.
