Usual Signs of Under Feeding...?

My plants were vegging from Nov 14th (when they were newly established cutting/clones) to Jan 1st (when I put them onto 12/12).
First week I overfed them, causing nute burn and stunting growth - following 2 weeks growth was painfully slow.
Now they're around 22" high, average.

WHAT ARE THE SIGNS OF UNDERFEEDING?

The EC has never reduced - just steadily risen, so I have kept the res at EC 1.2.

I want to be ready if any signs appear....

https://www.icmag.com/ic/showthread.php?t=11688 there is a pic of an under fed plant i think in here. Yellowing is usually the biggest sign, leaf drop or really any deff is a sign of under feeding. I like to get on a feeding scheduling. Ime, 12-14 days after 12/12 first bloom nutes. 7-10 days later 2nd feeding, another 7-10 days another feeding and then 1 more and last feeding. This is what works best for me. some people like light feeding, more frequently. Some people feed every watering, i wouldnt recommend it. But feeding is also strain depending. some strains like and need alot of nutes, some dont.

You fucking idiot hes obviously doing hydro. Your going to feed 7-10 days apart? Wtf???

in hydro at 22" id say you should be at about 4-500 ppm. Not sure of the ec conversion off hand but yellowing is the biggest sign. You shouldnt see any yellowing in hydro. Its really not that common unless you dont have a ppm or ec meter and are using a calmag suppliment. Good luck and watch for shit talkers like that indica shits fellow.

I’m pretty sure it’s lock out, because when you overfeed ur plant locks out getting certain nutes which is why there’s signs of phosphorus difficancy aswell as nute burn.

The thread you're responding to is over six years old. I don't think any advice will help the situation ;)
