Fish hooks

Hello everyone, I’m a few weeks from seed on my first grow and seeing some issues. Out of four plants, many of their leaf tips are curled under resembling a fish hook, and one of the plants has some orange spots on its leaves. I havent really had any success in my research to diagnose. Sort of looks like nitrogen toxicity but the more examples I find online, the less I feel that’s the issue. Growing in Rockwool cubes/slabs. Ph sound 5.6, flora series nutes at 1 tsp per gallon (per part). LED lights, humidity 50%, temperature 77 degrees. Any help is appreciated.

Also, the strain is Bakerstreet by Tweed. The only available legal seeds to grow in a country where growing cannabis is legal. It’s supposedly a pure indica Hindu Kush.

Sorry its just called "plant moisture stress symtoms and solutions". It has good leaf curl solutions.

That’s what I had thought too. It started while they were still on half strength nutes with no cal/mag, and it was recommended to me by the hydro store (who I at least know grows good stuff), and he suggested increasing the nutes and adding cal/mag. I was leaning towards deficiency simply because nutes were only half strength when it all first started. The pics I have posted are after the nute increase and addition of cal mag. If it is indeed N toxicity, should I dial the nutes back to half plus cal mag? Also, should I flush with plain water for a feeding or two to “reset” the Rockwool?

As far as flushing the medium goes, it can't hurt. I always follow a flush with a feed, no waiting. Flush out the salt buildup, measure runoff to see if your actually getting anything, get the numbers down and then feed. It's good to let some flush water sit in the medium for 15 or 20 minutes then push that out with more. If using pure water like RO then you should add 100 PPM worth of epsom salt to the flush mix. Very low PPM water isn't good for the roots, something about ions and shit lol... So having 100 PPM going in you are safe.

In this case you want to reduce nitrogen so find out what bottle is providing the nitrogen and adjust accordingly.

Nitrogen is mobile so if you go too low you will start to see the lower fan leaves getting lighter green and heading towards yellow. At that point you know what was too much and what is too little and you can make adjustments accordingly.

Order some illegal seeds just to get that bad to the bone feeling. If Trudeau comes to DNA sample the plant just tell her it was a seed you found in a jar of shake ya bought at the legal outlet.

Ok great thanks for the advice. I forgot to mention my setup is recirculating, I don’t know if that makes a difference in addressing the nitrogen issue

It will be one of two things, or perhaps even both; pH and an incorrect feed program. I would simply look at both and be sure you're where you're supposed to be. Both, in your style of grow, are HUGE! Good luck.

I’ve been keeping the ph between 5.5 and 5.8. You may very well be correct being on an incorrect feed program. These are the first of any type of plant I’ve ever grown so I’m a total rookie and wasn’t positive about when to start nutes or when to increase them. They are all a couple days shy of 4 weeks from germination, Grew to 5 nodes and then got topped at the third node to start a manifold... I really don’t know if they are growing fast, slow, or average.

Yeah root problems too wet or bpund or over fed flush her with a cleaning solution or just 0 ec water

I changed the nutes out to 1/4 strength a few hours before their bedtime last night. Hopefully in a couple of days they will start looking better, but as of today they don’t look worse. Do leafs recover and uncurl or should I only expect to see new growth looking better?

What soil? Does look nitrogen toxic

Yea man you upped the nutes double and added calmmag with also has nitrogen though not a lot. I’d say you’re toxic
