Bugs, burns or light? Or all 3?

Rossco...i had same problem with the leaves as your color...i ended up mixing up a espom salt mix and spraying them...it worked ..leaves went back to normal..i did it twice with in a week ..then i watered some in for 2 waterings to be on safe side..never came back...

as for the chewers..try putting a few yellow sticking strips in there incase its a flying bug...I have caught moths in them I never seen and few other critters...but your bug damage is very minumal..the strips will just let you know if any hidden critters there...if its a crawly bug just keep looking around...does not seem your infested..maybe a rogue bug in there...

I grow in soil and have had similar problem with the leaf curl, and could not resolve the issue.. But I noticed less problems in my grow room with temps in check and making sure every watering they get a good drench to 40% run off and since I managed that I have been having really good growth... No bugs in there I'm just guessing it was caused from not watering properly and salts built up.. Hope this helps buddy...

Cheers for the reply mate.

Epsom salts u say? So I could be looking at some sort of magnesium deficiency? I'll have to purchase some and give it a light run see if helps out.

As for the beasties, definatly going to invest in some sticky strips cos there illusive little twats. Was a decent comment on this thread about bugs in the medium which eat roots and leaves can show signs of damage so gonna have a research into tht aswell, as one of the new leaves has a perfect slice across lick a razor cut not a bug bite. Treat with py spray 3 days ago, since noticed new damage so gonna reapply and get the sticky strips. Cheers again Breda

Yeah I did let me coco dry out too much, a while back, then went on a strict feeding less but everyday schedule, to the point my run off is very close to what's going in (just under). Ph still higher on runoff.
So many problems haha, might have to try up my runoff to 40% for a few feedings, currently at 20%.
Cheers for reply mate

Sory I thaut u said to me bout Epsom. But yh do it like ur flushing/ leaching. It's worked awesome for me lmao I try to stay away from the ph meterunless I see a problem otherwise it more problems.

@Labs Dexter I was the same, up until a few weeks ago when I started noticing noobish errors, leaf damage and panicked and got a ppm meter and so on.. Since then it's been an endless game of numbers, and I've still got problems. So was it even worth it lol.
Least there still growing and not stunted, I suppose.
Would u put them into flower on Sunday? ( was my chosen date). Seen lots of posts sayin not to flower if u have problems cos they'll get worse. Cheers for replies mate, all help is appreciated on this long journey of learning and fun. And it's only my first one haha, but defo hooked ha

it might be condensation from the leaf above drip down to the next because it really doesnt look bad, one question is there little white speckled dots if so thurn leaf over and look for mites but it doesnt appear but hard to tell from the pic

put a fan on her directly if it is condensation.it happens often because two leaves touch and boom water drip and light magnifies and burns the central spot like that

First time in over 7 years I've ever had anything like this! Had to post!

Can you guess what bug did this?? The culprit only got in the room yesterday as far as I can tell. Only 2 effected leaves in the whole room! ¦0)

@tokalotapot I had noticed condensation on a few of the leaves. Good shout. Defo got bugs tho. Literally 5 mins ago, was in feeding and noticed a tiny black fly stuck to the wall, and one drifting around the room, killed the bugger flying. Where the hiding haha

Well the answer is............. It was an Earwig! Madness!

@TheHornyCulturis Haha I thought u was asking, not quizzing. Where did u find him lurking? Defo think on of my problems is gnats, leaf damage and 2 black fly have been spotted lol. War time

War indeed!
I check my plants carefully every day. Noticed the worst leaf first, the bugger was hiding under the second one he was munching on!
Never actually knew that earwigs would eat cannabis plants to be honest! I found that very strange but a google search tells me they'll eat almost anything!

that's caused by insect bites I believe, tiney pinhole and less, no biggy, at least where I reside in wales .
cuts on leaves usualy point to wheevle activity (bug bites roots and leaves show cuts)
Stress must be a factor, as ive got the cuts but no bugs. just as a precaution I removed it from soil and plonked it into my aeroponic setup.
ill try a photo

Your looking like u had it right sir
I've since discovered 2 tiny black flies (one dead and one drifting around the room). Thus supporting your bitten roots damaged leaf theory (as I'm aware the larvae eat root hairs) maybe the reason for slices and undamaged holes in leaves. And obvious damage with discolouration might be of the adults/winged.
@Indacouch to you aswell with the little flies comment... Many thanks amigos... Onto my next battle lime green leaf tips haha.. TBC

What strain is it? If it's indica and you have some space I found mature veg = mature nicer budsas for sativa or haze dominant then I don't know because I'm growing my first delahaze and I vegd for 5 weeks from sprout ... And as for numbers for the ph what not I buy bottled water ph is 6.2, every two or three watering I put raw honey or molasses is good to keep n feed with your water, that helps with root building and sort of keeps ur ph level every time. I use mg root boost mixed with peat and the peat builds salts fast and lowers the ph...that's another reason why I leach allot is to make sure that when I test my run off its equal to what I pouring in that way my soil stays on a level I like n plants just grow nicely I mainly have stress of trimming/ defoiliated lool. It gets less stressful this is my third lot my first grow was terminated by spider mites on last two weeks of flowering.. It gets easier and less stressful aslong as you make it easier but I'm still no expert that's why I joined RUI buddy

i see black specks on that pick. sure looks like the devil to me spider mites telltale sign black specks crawling under the leaf

Spider mites are the devil .....lol

@tokalotapot and @Indacouch surely not haha, I thought I had gnats, u got me thinking now haha. Gonna have a hunt for these little devils just incase I've got them aswell lol.

@Labs Dexter it's and indicate dominant hybrid. Super iced grapefruit ( diesel x chronic x skunk1) yeah may run it a little long cos space isnt a real issue.
Heard of molasses but never heard of using raw honey, gonna have to have a little look at that. Cheers again bro
