Salty Plants? Necrosis, Clawing, Very Short Internodal Space...

What did I do to these poor plants? And how do I fix it?

These ladies were bought as clones from a dispensary around 12/1 and they've never looked great. I thought they'd straighten out and take off but maybe I'm holding them back.

This is my first soilless grow so I'm sure there is a lot I'm doing wrong. I'm using Bruce Bugbee's peat recipe (50% Peat + 50% perlite/vermiculite + 40g/cuft of Dolomitic Lime + 10g/cuft Gypsum) and Jacks 321 nutes.

I think the problem might be potassium/phosphorous lockout. I mixed my previous res at an EC around 1800-1900 and seems to have burned them. I diluted the nutes with RO water till the EC dropped to 1600. I gave them an extra long watering at 1600 and measured the runoff at just above 1600. I'll measure the runoff again this evening.

Current nute mix: pH: 5.7-8 & EC: 1600 uS

How do I make them healthy?

Thanks!

Wowzerssssss!!! Boy if that aint a claw if I ever seen one! Back off on them nutes quickkkk! Less is more especially with these sensitive baby’s! Personally I would leach them with proper ph RO water for days until you see those leaves pointing ☝ if you have means of running RO would definitely recommend it over tap. What’s temp and rh? Love for renfro to chime in on this

As a non-hydro person, this is interesting to see. What crazy excessive amounts of synthetic nutes do to a plant. Good luck, hope everything goes well and we all learned something from this.

You gotta get that number down, back off to about 1,000 ppm or even 800, run that until their pumping then u can start raising it, up 200ppm a week.
Im not going over 1400 with current crop.

Thanks to everyone! Maybe they'll produce the first pickled buds.

I flushed the plants with pH'd water till the runoff was under 1000 uS. My res is sitting at 900 uS at pH 5.95.

Thanks again for all the help!

That's how you cook 'em. Wherever you got that advice you should quit listening. An EC of .8 -1.2 is plenty for most plants.
