Deficiency after tent switch.

Hello I was wondering if anyone had any guesses with what was going on with my plants. I recently moved them from my 4x4 and they went from looking great to not so good in a short period of time. I’m wondering if it’s nutrient deficiency or stress or maybe a mix of both. They went from 18/6 to 24/0 because my intentions were to flip them soon before they turned on me. The humidity is also only 40% in the new tent at the moment. They also got scrogged and lollipoped. There’s still a week due too another top dress but they are pretty big so I’m thinking maybe they’re just eating fast ? I added a photo of them in the 4x4 for comparison

Check this thread, you might find an answer

looks like heat stress/ over watering but i could be wrong .

Put them back to 18/6

Are they under different lights in the 4x4?

Good day Sir! What I can say is start monitoring as many conditions as possible. This will in turn provide us and you with details to properly diagnose plant problems/pests. In my experience what I can tell you is this, magnesium deficiency can come from a few things, nutrient lockout, temperature, PH, V.P.D, and more. Your leafs tell a story of interveinal chlorosis, that is yellowing with green veins. Mag is mobile meaning you will see bottom/oldest leafs yellow first. To correct this use Epsom salts, start slow and low first, anything in plant available form tends to be best for fast absorption, also you can foliar spray with some mag supplements =) This easily corrects minor deficiencies. Temperature below 65 can inhibit mag/nute uptake. Common on concrete floors with pots directly on top. Did the temperature of you water change? If you're in a new room and let your water acclimate, this could be causing shock, hence the purple, another story being told. Forced cold air? Look at variables that have changed since they were happy and healthy. Remember adding more nutes should be last case scenario!! It's easy to just dump nutes in to try a fix a problem, don't! Work outside, towards inside! Best of luck, let me know if you still need help!

Looks like you're light burning the shit out of them. Why are you running 24/0 light cycle? Switch to 18/6. There is no reason to run 24/0. You're stressing your plants.

Yeah I know just a lazy mistake I didn’t wanna re program the timers . Probably light burn I guess I do have two scorpion Diablo but I did have them turned down.

It's a learning experience and you won't make the mistake twice. I can assure you that Congratulations! You just learned how to be a better grower by hurting some plants. And we've all been there. One of the best growers I've ever met told me this, "I had to get real good at killing plants before I got real good at growing them." He runs a 50 plant outdoor farm in Oregon and is the owner and operator of Jefferson State Seed Co. He started right where you are
