Whats up with my plants??

[Troyblack99]

Hey y'all! Whats up with my plant?? I recently moved my girls from a room to a tent under a bigger light.and Scrog. They seemed to be loving it, but after a few days some there seems to be some intense yellowing on top growth. Any idea what could be going on?

Went from a spiderfarmer sf2000 to spf s4000 temp and humidity are on point for the most part. Grown in ocean forest. P.H. 6.5

Looks like light burn, can you move the light up?

 

[Troyblack99]

Really? There under an led... but maybe another 6 inches

Looks like over fertilization to me - burnt tips. Generally lack of something required by the plant starts from the bottom up (like nitrogen deficiences). New leaves aren't doing the claw or appear to be stressed from too much light. Just a thought, someone else should be able to put you in the right direction.

Are u using any cal/mag?

Tips can be from poor watering if you forget or you underwater frequently

thats not light burn, you dont need to move your light

 

[go go kid]

do you have any seaweed solution you can feed them with??

 

[Serty97]

Normally would agree but started right after moving under stronger lights, can’t be a coincidence. Also looks worse on upper leaves which seems like burn.
Here’s a pic of light burned plant for reference.

No but I've been feeding them biobizz grow, do you recommend seaweed extract?

Also; Moving under stronger lights the plant will uptake more nutrients/ andd if any are missign it will start to throw deficiencies

Good point

if uit was the lights, the lower plant branch heads wouldent be showing the same symptoms as they are far away from the light

If you're not sure, you could always test with another tent, but keep the light higher, same nutes, everything else. It really looks like too much light to me. Plants want a reason to stretch, give them a reason! Sometimes the light will outpace what rootball the plants have developed so far.

Haven't seen anyone ask, but what is the distance from the light to the tops? and how high is the dimmer? It doesn't need to be blasted in veg on 100%.
I'm thinking the light may be too close, but I do believe that if the nutes are dialed in right you wouldn't get any light burn from 18" but the PPFD is high. I would pull it to 24" from wherever you have it, and see how it goes. I would also suggest more calmag than usual. I'm not a pro, but I do have the sf2000 and the sf1000. They can beat on those tops if you don't stay onto of raising the light when the plant grows vertically. I hope this helps in conjunction with other advice given.

personally it looks like nutrient deficiency have you been checking your PH?
