I'm looking for advice on what the problem is with this leaf.
I haven't seen many with this issue but would like to know what steps to take to correct it as its probably a warning sign.
This particular leaf came from the bottom of my 2ft blue dream.

grown in hydro with constant nutes

ph 5.5 to 6.5, likes to stay above 6


ppm 900 or so, sometimes over 1k

feeding cal mag botanicare and general hydro starter kit

hydroton medium with nute solution spraying the roots every 15 min

all indoor, 70 to 80 deg, 40 to 60% humidity

some leaves show burnt areas but they might be touching the lights at times.

T5 lighting only


Thank you!

looks like insect damage to me

Ah yes. This. It's not bugs but it looks like it. I forget what does this. Hope that helps

Yep, definitely insect damage.. Look around for caterpillars or any other insects that might be eating away at your plants. Cats will also chew on leaves if there is one that has access to your grow area

Prevent insect damage use Neem Oil 1 time per week to prevent mold too

I haven't seen any insects around but I'll do search. thanks

check in the soil, they might like to hide in the daytime

Yes! Definitely insect damage, ha... Get some lady bugs and let them do the work for ya

That looks like the work of a small caterpillar. Look closely under leaf around buds. Even pull buds apart if you can't find the culprit. It will shit in your buds and cause catastrophic damage if left alone. Need to find ASAP. And to other posters.....he is in hydro not soil. And OP I agree with neem oil use. Once you find and kill the Bastard use it bcuz it works to prevent further infestation. Good luck

keep your cat out of the grow room.

So I trimmed off any piece of foliage that wasn't immaculate and searched but didn't find a bug.
I also put out some sticky aphid traps.

I'll continue the search tonight.

Here's another pic of another leaf. Do you think a bug did this or its it a nute issue?
