Can anyone tell me what this may be?

Sounds like a plan, then give them a few days and post pics so we can check them out.

Try to drop ph with your next feed.And slightly up your feed amount.We hope all this helps.

thanks

 

[StacyDu]

Keep us posted on how they do

I will, thanks!

No problem!, I will

Probably just underfed at this point but should be good.

I don’t know if this helps but I looked at them briefly this morning and didn’t notice anything, I noticed it when I got home from work today. So I think it developed pretty fast (like 24 hours or less). Would it still be phosphorus mixed with high ph?

Yes, in Promix or coco changes occur quickly. But you can reverse problems quickly as well.

Hi everyone, this is my 3rd time growing (2nd time for autos). The 5 autoflower plants are called Expert Gorilla. They are between 4-5 weeks. And for the soil I used pro mix - hp mycorrhizae with about 30% destiny organics - dark matter My day temp is usually between 76-81 and night is 70-75, humidity is always at around 45-50%. I try to keep the water ph at about 6.5-6.7, I just took the soil ph which is at about 7.2ph (I know I need to try and lower the soil ph)
I gave them Green Planet nutrients with a little cal/mag 3 days ago at about 850ppm
I’m using a 125 watt cfl for the lower half of the plants, 2- 1,000watt led’s (1 blue/red and 1 yellow) and 2 - 600watt blue/red led’s. Pulling 650watts from the wall Now this is deficiency is only on 1 plant
(3 leaves that I can see). Any help would be greatly appreciated. Thanks

hey guys I haven’t had a chance to get any phosphorus yet, I’m in a bit of a crappy relationship with a stay at home girlfriend who’s on her stupid fb games for 8+ hours/day while I’m stuck taking care of a teen, 5 year old and 4 year old whenever I’m not working, so I’m VERY busy. Anyways today I’m gonna look at the ingredients of my “advanced nutrients” and the “green planet” nutrients that I have and see which one has a good amount of phosphorus in it. Attached are a few pics of them getting a little worse. If anybody thinks it may be something else just let me know.
I will let you know in a few days again and post some more pictures. Thanks again for all your help.

Can I use “bud booster” by “green planet” for phosphorus? When I watered them almost 2 days ago I added 1/4 teaspoon to 7 litres of water with a little bit of “overdrive” by “advanced nutrients” and hoped that would help. But I don’t know if phosphate can be used as phosphorus.

Same thing actually, you’ll have to watch your unaffected growth to see if it’s spreading. The damaged leaves won’t recover.

Ok, it is spreading. But if I did use that bud booster stuff and a little of the overdrive stuff, that should’ve gave them plenty of phosphorus!, then should it be getting worse?, or should I try another does in 2-3 days or so?
Those first affected leaves are drying up now and doing the taco. Should I cut them off? I also raised the 1,000 watt lights to about 20 inches and when I watered them I made sure the ph was at around 6.2-6.3 but the soil ph has only dropped to 7.2.
Any other suggestions or are we sticking with phosphorus?

Even after giving it a good dose of phosphorus, it is spreading and it is on other plants and leaves now. The ph of the last watering had about 1 cup+ of runoff (almost 2 days ago) was at 6.2-6.3 but I just checked the soil ph and it only went down to 7.2, I also raised the lights to about 20” just in case. My question is.., for my next watering would it be a good idea to get the ph of the water down to about
5-5.5 in order to lower the soil ph enough?

Give them a couple more days, what’s the temp like at the canopy.

78-81 daytime and 70-73 nighttime

That’s very good for temps

Here are some update pics of the deficiency 2 days after some water ph @ 6.3 and some phosphorus and raising the lights a bit.

Give it a couple of days, in soil it won’t change overnight.

Hey guys, here’s some updated pictures of what’s happening 22 hours after a heavy feeding. I didn’t measure the ppm this time but I’m guessing it would’ve been 1200-1300 ppm because the one that is turning light green. I set the water ph at about 5.8 because the soil ph was at 7.1-7.2 still. Hopefully in a few days they start looking better. If you have any ideas just let me know, thanks
