Hey guys sorry for bothering but woke up today to some odd color brown spots on some of my auto NL plant. She is pushing 6 weeks and shes under 2 1000w blurples. She is in ocean forest and ph is always between 5.8 and 6.5. I just started her on fox farm nutrients yesterday so I’m wondering if that’s the issue? She gets calmag twice weekly and I was using bergmans nutes but I just switched it up. Also I didnt start nutes till week 3 and was light with them. Please let me know your opinions guys and thanks.
Discontinue nutes! You are showing N toxicity and looks like calcium def.
You need to flush with a TDS meter handy to check runoff.
Stop giving nutes? And I give it calmag every week 5ml of it… as for a flush I have never flushed before… can you be more thorough
N toxicity can cause lockouts.
Would it be safe to say you have droopy, clawing dark green leaves? If so then yeah; a flush.
How to: I do like a product called Flora Kleen by GH and FF makes Sledgehammer: these are mild detergents safe for plants, to dissolve salts in media. Follow that with something like 5 gallons of purified water. Let it dry out.
You should invest in a TDS meter before going too much farther. I’m assuming you have a PH meter as well.
Plant will recover and you shouldn’t even lose leaves, unlike an N deficiency. But continue with the cal mag after doing a flush. You will be adding bloom nutes but it would be nice to know how depleted your soil is after flushing.
Also: Fox Farms recommends flushing at certain points in the grow.
So I flushed today with 1 gal of 6.2ph and a tiny bit of calmag. I put my ppm and tds meter in the runoff and honestly I have no clue what the numbers mean but one was 1000 and the other was 1800. After the flush I stopped it off with some new ocean forest soil because I was starting to get tunnels and soil was making like water ditches along the edges and middle, I’m gonna order the sledgehammer stuff I read about that earlier and I have another question in regards to what to do with nutes after this… should I just finish with the bergmans or should I stay with the fox farm trip? And I put fresh soil to top it off AFTER the flush. Thanks guys
I capture 1/2 cup after it’s drained for a bit. Measure TDS and PH from that sample. If a product is used like Flora Kleen, don’t take a runoff number then as it’s going to be higher. A proper flush is spelled out on the package. Just follow that.
@Myfriendis410 so I flushed with 1 gal of water yesterday. It had a ton of runoff. I ordered sledgehammer aswell. I have the vivosun ec tds ppm meter and I have no clue how to read it… when I checked the runoff the numbers were 1800 and like 800. None of my other plants have these spots. Only this 1 in flower.
Let it dry out and resume normal watering with cal mag. Monitor plant for changes but remember damaged leaves will not recover. Look to new growth.
Question… I have 2 autos and 2 females and 1 of the autos is in flower the other is not. I’m running 18 on 6 off with the lights. Can I switch to 12 and 12 to push my other auto into harvest and my females? Or will it cause problems to the 1 I have in bloom now that’s giving me problems ?
Sometimes you have to stimulate autos. That will work.
