My HPS does that to my plants buds that are at the top. Never seemed to have much of an effect as long as all of them don't stop growing. Could also be a lock out wouldnt hurt to run a few gallons of water only through it. The damage isn't going to recover though you can only prevent more damage

Potassium deficiency is my guess. I'm no expert though.

How far into flower are you?

How far into flower are you?

It's an auto and to be honest it started flowering at 2 weeks the plant is 35 days old. Everything else looks good. It's in happy frog soil with a mars ts1000 light.

How far into flower are you?

It's only in the upper growth most of the problems I've ran into are usually on bottom first. I'm no expert I've grown may 10/12 autos, but I think its immobile. Just not sure what. I'm thinking potassium or iron deficiency.

I was thinking that or iron

Thanks I flushed my runoff ph was 6.3 if I'm not mistaken that's fine.

Happy frog only has a 5-7-3 NPK ratio. Kind of weak in the P and K for my liking. Maybe this is why people bottle feed to make up for what the soil lacks during flower. Flushing would seem like a bad idea because you’re just washing all the nutrients out of the soil. Top dressing would be the easiest way to add back in what you washed out to replenish the food. She might be hungry for Potassium and Phosphorus.
