LED Grow Light Forum

If they keep growing you may have to gently tie the tops down LST style.

I read that for autos you supposedly can kinda stunt there growth if wanted by switching from veg nutes to flower. They say that they will stop growing and focus more on flowering ......... i gave them veg nutes cause i wanted to see if i can get them to there potential and hopefully they stop growing themselves and start flowering. LST , Training, IS possible however yes i did read that you have to LST very very gently with them! And they say dont top at all.

So i woke up this morning to this!!!!!! Humidity was at 50% temp was at 24c nothing changed in my nute line up. Nothing new ..... there 18 inches away from the lights . And even the very tips are turning white ... so WTF? Suggestions? Whats with the leaf curl?

There some better light pics

hmmm. that doesn't look so good.

i would say "when in doubt, flush 'em out". when's the last time they were flushed? maybe a nute build-up?? not sure though. a good flush will never hurt a plant though.

good luck!

Thats actually what i just finished doing! lol I gave them a good 1 gallon flush with some fox farm sledgehammer...... hope it works!

Maybe I should of used more water to flush. But after searching for a answer I am thinking its a nitrogen overdose.

You said nothing changed nutrient wise. Just make sure it's not a pH lockout causing the N toxicity. How cool is your res? Roots look ok?

Lol. I am in soil! Lol. I am pretty sure its a Nitrogen overload. I think. I searched and searched and found lots of pics with those turned down leaf tips. If you look at my pics from yesterday. You can see in that pic just before I gave them a feeding the tips are turned down. I took them out this afternoon and flushed them. I did take my PH soil pen and it was kinda all over the place. Anywhere between 5.8 - 7.1. So. I just flushed. I'll leave them alone for a while and next Friday introduce nutes to them again at about 1/4 strength.

It's been one of those days...all year. Good meds though.

Ram's horn usually is too much N but 6.5 is the target pH for soil so keep an eye on it until you get it where it's supposed to be. 5.8 is too low and 7.1 is too high. When it gets very high N is one of the few it can take up so cover all your bases.
