Need some help

Hello,

I am a newer grower with about 6 harvests under my belt. I have gone from 1 and 2 plants to a bigger set up with a tent and 7 plants. I have 2 2000W led lights. Exhaust vents. Humidifier and track temperature control. I screwed up and numbered my plants. All different genetics. Garila Glue,Big Bud,skunk #1, Cali Kish and final Bruce Banner. The plants are almost 7 weeks old and I noticed they would burn with the smallest amount of “Garden Rich root and grow” so I stopped using it. The plants look great. About 2 weeks ago I started seeing burn on the ends of Leif’s. I cleared the damage and raised the lights. Over the past 3 days I have been seeing the same thing happening. The tent stays between 68 and 70% f and humidity between 45 and 50. I only use rain water and find myself watering about everyday. The death I am seeing is on the top nodes. The canopy is right between 625-690 umLu’s which is low from what I’ve read. Here are the pictures.Looking for help from experienced growers. Also I did a Ph test a week ago and was right at 6.0.
Also my Skunk #1 has 2 main nodes that almost look like completely different plants. The one side really healthy and the other a lot of Leif damage.

Need more info: what are you growing in? It looks like soil and watering soil daily is way too often.
What are you feeding and at what levels?
And when you water are you using tap and/or adding any cal mag?
Lastly, when you say you checked your ph, how did you check it?? Runoff? Slurry test? What exactly do you mean by that ??
Give us those details and if I can’t help you someone will…
Cheers

Good spotting that little detail. The leaves do look a little overheated. You can’t let the temps climb up nearly that high. 85f is about as warm as I’ll go but I usually shoot for 80-82 during veg.
Would still Like to know the other details to make a more informed opinion.
