My ph is good I’m watering with runoff using fox farms trio have 12 plants this one is giving me trouble I’ve tried flushing giving less nutes more nutes been over 2 weeks can’t figure it out? Starting to think maybe the calcium in my tap water blocking potassium or something?
Have you checked very closely for bugs? You may need a loupe of scope to see most of them
I haven’t looked closely for bugs I definitely will do that. I have been neeming them every so often, but my other plants are bug free.
It can happen to just one plant at first. Some of it looks like bugs and other looks like nute burn. For the nute burn just watch new growth to make sure it’s looking good.
If you are using Neem on them be sure to emulsify it properly and spray at the start of lights out so they dry thoroughly before the lights come on. If you’re already doing thbith those, I’d try reducing the concentration of neem.
I checked for bugs I haven’t seen any. I haven’t given nutrients in a few days and it seems to be getting worseUploading: EB5D489F-05D3-4AC8-BEF3-724E7732E61F.jpeg…
Looks like bad nutrient burn. but I’m no expert
@Borderryan thanks for the shout out
This doesn’t look like pests …
Looks more like some type of nutrient problem or deficiency
Which isn’t my thing lol …but it needs to be my thing too !!
OK, you say your ph is good… have you checked ph of the soil? You can do that by doing a soil slurry test.
So I did a slurry test and my ph is super low I use the drops and it said it was in the 4 range like it was red red
The drops can be unreliable. A good pH/TDS meter will get you much better accuracy. Apera and BlueLab both make single pens that do both. The Apera pH20 is pH only at about $50 and the pH 60 does pH and TDS for about $90. Invaluable purchase(s). I don’t know how much BlueLab is, but they are pretty highly recommended.
I don’t have a pen, I really need to get one. Had a cheap one but it broke . I did a slurry test on the soil after I flushed it yesterday and today the test I did said my ph was lower than 5. I use the general hydro ph drops I’m not sure how reliable they are but I’m betting my ph is low reguardless right?
I will definitely get one soon.
Yes, your ph is low… even if the accuracy of the tests is:
ph pen +/- from .01 to .1
test strips +/- .5 to 1.0
your ph is low
You can raise it by top amending soil with lime or limestone. Just don’t overdo it… try a small amount, wait 3-5 days and test soil again and also watch for new growth.
