Please help! What could be causing this?

[Capt. Trips]

Yesterday I noticed a couple small yellowish/brown spots on some leaves. Today it seems to be worse. I've searched the forums and can't come up with with an answer. So many of the different problems look the same to me, so I'm hoping some experienced growers might be able to diagnose this. I'm completely clueless about what to do.

These are in my greenhouse, and they get around 8 hours of direct sunlight per day. I've looked closely and can't see any bugs or anything like that. I have not yet fed them any nutes whatsoever. I've been giving them straight water whenever the soil seems to be dried out a bit, which has been about every three days. I transplanted from one gallon pots to ten gallon pots just over a week ago, and the soil they're in is this -- LINK.

Again, these spots only showed up just yesterday and already they seem to have gotten worse in just one day. The tear in the leaf in one of the pictures is something that I did by accident. It was not eaten by bugs.

Please, I'd appreciate any help anyone can offer.

looks like bugs

I second that. Are you growing outdoors? Either way looks like bug bites to me.

Edit: could be nute burn too. Make sure when you water your not hitting the leaves.

I've got them in my greenhouse, but I do keep the door open when it's hot. I've looked at them with my 100x loupe and can't see any bugs at all. Should I treat them with something?

Spray them with neem oil. Smells pretty

Newb here but they look ok to me. I see a couple of water spots. Maybe very slight nute burn on tips. R u foiler feeding? Not sure if i would do much of anything at this point. Perhaps keep a close eye on them and if it gets worse then treat them. What are you feeding them?

Its nothing don't change anything.

I've fed them nothing yet. Just straight water, no nutes. I've looked and looked and looked again with my 100x loupe and haven't seen a single bug. I hope you're right about
it being water marks. I do tend to be a bit sloppy when I water. Thanks for the reply.

 

[Po boy]

let them grow! they'll be fine. GL

 

[Capt. Trips]

Thanks everyone for the replies. They haven't gotten any worse, and they really seem to be taking off in the last couple of days. I think at this rate they're going to outgrow the greenhouse by the end of the season.

Some spots are telltale signs of somethin' bad happening. These spots tell no such stories. They look healthy and well cared for. Grow on!

Good to hear. Thanks!

I did not look at your soil link. They look really good for no ferts at that size. It looks like a hopper might have got on them. They can eat and run. I think your soil might be a little hot due to the fact they look killer and you have not fed them. Also a 10 gallon pot with a plant that small might not need water for over a week. Let them dry so they will grow them roots. Now that I opened my blow hole I will read about your soil. What kind of ferts will you be using? Chemical or Organic? If organic I would be putting some teas and Hi-Brix Molasses on them. No nuted per say but will get the soil alive to process your nutes when you start using them. Lookin Good Bro..

Noob here but when that occurred in my grow my mate told me nothing was wrong and to man the fuck up! We want THC I see nothing wrong with giving them some TLC. My mates seem to differ.

 

[Da Mann]

OK. No bugs. Read up on soil. Only problem I see with it is they have no place that sells it in the States. Just get the watering down and keep a eye on PH. I want to try that soil now.

Thanks man, much appreciated!

That hole in the leaf looks like a bug ate it, but it was actually me trying to hold the leaf and focus my loupe and I accidentally squeezed too hard and ripped it.

I've transplanted them twice into new soil, so I haven't really felt the need to feed them anything yet since the soil already has some goodies for them. These pots they're in now will be their final pots though, so I think I might start feeding lightly in a few weeks. I have some locally made chemical ferts that the people who run the hydroponic store here swear by. I'm just watching for any signs that they're hungry. I'm afraid of burning them.

There is a lot of ways of doing things. Regarding transplanting I never do it unless I do not have room and need to give them more root space. Like waiting on a place for them. Smaller pots mean smaller lites and area. With your green house I would put seedlings or clones in your final container at the start. OK. The plant will not seem to grow as fast because it will be growing roots but once they are good the plants will take off,. You can watch them grow. I have seen as much a 4 inches in one day. But 1-2 is the usual. These are looking very nice. Do not worry about the edges unless it gets worse.Next time you come south bring me some dirt.

I'm a total noob myself, but it seems to me that a little TLC is not going to hurt anything. If I'm going to grow it, I might as well try to do it right. I love smoking good bud, and if a little TLC could be the difference between dank buds and ditchweed, to me it's a no-brainer.

I think I might try starting them in final pots next time so I can compare results. I started them under a small T5, so I only had room for small pots. I'm thinking about buying a good light setup though. This is the first time I've ever really grown anything at all, so I was pretty unprepared. I think I'll be a lot more ready next time.

The soil seems pretty good. I was pissed that I couldn't find Fox Farms up here, so I went with this stuff. Get some Ocean Forest and we'll make the swap at the border
