Deficiency, virus, or fungus. The has been following all of my plants for the better part of a year now (different strains). Root zone ph is 6. Temps 74-77 24/7. Humidity can range from 60-74%. Coco/Perlite mixed 60/40. Feed is 5-11-26 hydro, 75-100% strength.

Wink It looks like you have several things going on at once. Looks like a cascade effect; one thing leads to another. I'm guessing the green showing on the perlite is mold or mildew. I have a suspicion of what is happening - I have not grown anything but hydro for some time now so before I put my foot in my mouth yet again I'm going to direct you to the following links on GWE and see what you come up with, by then you'll either have it figured out or another member who grows in your medium will have stepped in and helped to give you a more definitive answer. Happy Pharming! Your attentiveness and desire to do better bode well for your cannabis cultivation future.

Hello. Noticed a spot on one of leaves and yellowing to purplelish color on tips. She is in Pot4pot Superb Soil. No nutes added as I was told that Superb Soil is hot and their soil will carry the whole grow. I been watering just ph water between 6.2 6.5 a lil higher sometimes as it drifts bit never went over 6.8.

[BU2B]

Hey Jroc I think you've found the one big draw back of growing with a hot soil mix. As you've only been adding water there is just no way to cut down on what nutrients she gets. It looks like slight nute burn on some of the leaf tips and 'the spot' looks a little like she could use some Cal/Mag but other than that she doesn't look bad. AND unfortunately I really don't know of a way to avoid the nute burn as you can't reduce your nutrients. Keep on Keeping on, not much else you can do. Fingers crossed for the best possible outcome and Happy Pharming!

[Jroc]

Hey thanks for your response. So I went to a local hydro store and they said the same thing you just said. "Nutes already in there". Thay gave me some recharge to try on her. Gave her half tsp. in gal. h2o ph 6.5. They suggested I remove sick leaves. This is her as of yesterday.

[Jroc]

So I think she is looking better. 48 days from sprout. Now I am trying to identify this leaf issue on my other girls. They all have this going on a couple of leaves. I was thinking ph issues. I last watered/fed last night bit three days ago they got 8ml advance nutrients ph perfect sensi bloom 4 ml big bud carbo load bud candy sensizym 3ml fish shit. A&b was upped 1ml from last feeding. The others only up half ml. New addition is the fish shit. If someone can help me identify this new issue, it will be greatly appreciated. The following is all the girls. End of week 7 tomorrow. Six autos 3 super skunk 3 northern lights. 4x4 5 girls are in pro mix hp with Mycorrhizae. The other is in superb soil. I have gotten this far but I don't know what I am witnessing is great good fair poor as I have never seen the plant grow. I am just used to reaping the benefits. I want to appreciate my medicine much more now. I don't know what happens next or what to expect.

It looks like you're going to have some nice flowers. Nice recovery! I wouldn't worry about what you can't do anything about for this grow. It does however give you food for thought for the next grow. Yellowing on the lower leaf shown below looks normal for the age of the plants and your growing medium. My guess is 'about' 3 more weeks for your auto's before harvest day. Once again, we have the hot soil issue so keep that in mind for the remainder of this grow. Have a look around GWE and the forums for auto photo's and grow journals to give you a better idea of when your girls are done. There are many here that grow some amazing auto's, round 'em up, PM them if they allow it if you have questions or comments and welcome to the Phunny Pharm! I'm going to toss out a few names of some good folks for you to contact re-auto's Canuck147 Bowhunterwoody both have a lot of combined experience that I think you would find helpful.

Hey Brother Thanks for sharing some of your knowledge and contact info. I wish you happy and peaceful growing always!

So the girl in hot soil I will give her some more recharge before flushing. This is last week for bloom nutes on other girls. After next week it will just be phd water. They say you can flush with fish shit but I don't know about that. It's expensive and will it affect the taste of the flower? One other ? if you don't mind. During flushing do buds continue to develop as far as fattening up or is what I see now what it will be?

[BU2B]

I grow photo plants in hydro so I really think a better and more definitive answer is best coming from someone who not only grows the same type of plants but also in something more closely resembling your growing medium. I would really be surprised if they didn’t fill in and fill out significantly in the next few weeks. I don’t know if he grows autos exclusively. but I do know that Going2fast has done a very nice job with his auto girls. You might want to give his journals a look and hit the stocking footed one up for advice. Also if you haven’t been yet you REALLY should go to Mr.furley ‘s Show your grow forum here on GWE. Furley is VERY helpful and knowledgeable and is another fine person and great resource available to you @ GWE. One last but important thing before I quit rambling… DONT OVERLOOK ALL THE RESOURCES AVAILABLE ON GWE! —> https://www.growweedeasy.com/link-gu...owing-cannabis

I don't think growers flush hot soil.

[Puglover1]

First grow I was using fish emulsion in veg for the nitrogen.

[Going2fast]

They look ok Jroc. Can't help you with the feeding as I only do soil and compost on my autos. Day 48 they look ok. I would get your pH to 6.5 for this stage.

[Jroc]

Cool, thanks I appreciate you Brother. Yeah so the Advance Nutrients I will run til day 60 or 65 til flush. I have a chart. I will follow. I did look up a grow as you suggested. This grow was Northern Lights and he went 12 weeks til harvest, that's about 5 more weeks. I will check some more out. Peace & happy growing to you Brother. Ttys..

Plants closing up instead of fan leaves pointing outwards, too much light/ppfd?

Telos 10 pro mesh 300w
Environment is very good

[SwitchH2O]

Looks like too much light to me. Fan leaves with furl up. They also get super green under too much light.


Cheers,

Yea think so too, first run with this new light. Hanging height 100cm and light dimmed to 200w/500ppf and its still too much.

My growspace is 95x65cm so definitely don't have to run
it at 100%
