Help!!! Foliar feeding always hurting my plants

What am I doing wrong? I just can't get foliar feeding right. Every time I do any foliar feeding within 3 days about 10-20% of the leaves on my plants either turn brown and die, or they dry up completely (staying green) and die. Here are the ways I have tried foliar feeding:

1. Wait until 15 minutes after the lights go off, and foliar feed.
2. 1 hour before lights come on I foliar feed. After sitting for 15 minutes fully drenched, I put the fan on maximum, and then with another fan (held in my hand) I work it until all the leaves have knocked off any built up wetness.
3. Same as number 2, but this time I run 15 watt CFL at a distance for the first 1/2 hour of light, then kick on the HPS.

I have tried (seperatly) each of the 3 above methods, and every single time I get the problem. I have tried this with Serenade, Kelp, and a milk solution (9 parts water 1 part milk). Each one of those were separately applied on different weeks. I just can't get foliar feeds! I am going crazy.

Please help me get this right. Thank You!!!

Im no pro but i don't think you should feed them during the night cycle.
You should spray after the light have been on for a while then after like 30 mins spray the leaves with fresh water.
A fan is always nice to dry them afterwards

Do you need to foliar feed? The easy answer is to provide ample nutes to the roots and don't spray em.

Sounds like you have powdery mildew, and your trying to get rid of it
rather than trying to 'Foliar Feed'. There's tons of info here about PM.
Good Luck

it s sounds like its not a foliar feeding problem.

if ya go with your #1 wait after lights are off and feed should never cause any problems.

what youre using milk for man? spraying on the plants never heard of that.

maybe your solution is too hot for the plkants so they get burned.

It sounds like it might be what your feeding them.
What is the purpose of your foliar spray. Are you trying to kill pests(serenade)?
Or feed your plants(kelp,milk?)?
I try to foliar feed every 48-72 hours up until and sometimes through week 5 of flowering. I alternate between feeding and straight water to clean the leave and allow stomata to breath.
I use a bunch of products from Advanced Nutrients and mix them all together with water and spray. I use iguana juice grow/bloom, liquid seaweed, fulvic acid, carbo load, tarantula, pirahana, and wet betty as a wetting agent(you could use a small amount of organic dish soap instead of wet betty). I like to do it either an hour before the lights turn off so they will dry but not burn under the intensity of the bulbs and then not be too humid at night, or I just lift up the lights an additional foot or two and then lower when leaves are dry.

When I foliar feed, plants go crazy and you can definitely see a boost in growth within a few hours(no joke!).

You obviously don't need all the stuff I use. I recommend you start simple, maybe something like earth juice micro blast and an organic grow/bloom. Make sure to use plain water at least every 3-4 sprays to clean leaves. Remember you need to be mother nature, and plants need rain to clean dust and dirt of their leaves and allow them to take in CO2.

Good luck.

Feeding too much... why not spray once, when lights are off.. once a week depending on what you are spraying them with... but I don't feed via foliar more than once a week.

Ps.. only foliar feed healthy plants, or plants where you know what their issue is and when you are attempting to fix the issue.

OK, this will hold true for many situations, including this one. When doing something that consistantly does harm..............Stop doing it!

I can,t say i've ever seen Mother nature foliar feed her plants, and nothing grows better then in nature...IMO

Milk?? that will dry and spoil and coat and plug the pores and kill the leaf.

since i feel i have the IQ egual to or higher then the average House Pet, and if i was constantly killing my plants with diff + strange products etc,

I'D STOP IT but thats just me lol

stay warm, GK

PS rinse the s--t off you plants and give them a break. they will love you for it.

Yes. Killing mildew. I have been working on my humidity problem, but it's not as easy as it seems. The serenade has killed the mildew when I have had it in the past. But with bad results otherwise...

Thank You for the help. I have been wondering if I should clean the leaves off with pure water after spraying. My concern with spraying with the lights on is because of burning the leaves. Any thoughts?

I totally hear you. I actually have my feeding dialed-in. With my drip to waste system I have perfect harmony of nutes. My problem here is powdery mildew. Also, being preventative for other issues. I have heard many people suggest weekly foliar feed of anti-fungle's etc.

many people believe that milk is probably the best for powdery mildew. Check out these links:

Google it. You will be amazed on how many people love this approach.

Check out a thread in the infirmary by krunchbubble about a product that completely kills powdery mildew.

Exactly! I totally agree. This is why I havn't been doing preventative maintenance for powdery mildew (in sprays), because of the past results. Though, once you get the PM, I don't have any choice... It's frustrating.

I'd forget foliar spray and go straight to bleach. Anything non porous (reflectors, fans, tubs, walls, floors, etc) gets scrubbed with a 5% bleach solution. Anything porous (plants, clones, soil, Rockwool etc) gets thrown in the trash. Until you get it out of the room, you'll keep getting it on your plants.

Bad results otherwise? I love serenade. I have seriously wiped out an advanced infestation of the PM at my buddy's dispensary (maybe 50 plants, just one grow room) with a SINGLE application of serenade. He had been using anti-fungals trying to fight the battle, but was loosing.

The key to using serenade is this: SOAK THE PLANTS. I mean literally go to town on them. It should look like you sprayed the plants with a garden hose for a while. The entire plant has to be soaked every square centimeter. It should be dropping of the leaves profusely onto the floor lol. Serenade works, but if you even leave a small bit of PM behind, it will just spring back up. When you soak the plants, wipe the walls and floor with rag wet with bleach and water. Or mix up a spray bottle like FB said. Get every surface all at once. If you soak the plants really good and do a bleach wipedown you can kick its ass in one day.

Edit: I also have found Zero Tolerance to work just as well at getting rid of PM.

Thank you for the advice. Yeah, serenade works for me but the problem I have is that it kills off leaves too. I know its not the serenade but the way I am applying the foliar.

Sulfur burner.... and cut back on frequency of feedings foliar wise.. straight water, I do it all the time as the plants love it, but that's lights on and while I'm in the room. Adding moisture to a dark place is promoting a prime environment for mold and/or mildew growth.

Uhh let's get outta kindergarten here kids, you have gotta ph ballance everything. Foiliar alkaline 8.0, and roots I prefer 7.0, sure just a tad more in the acidic direction. You gotta do your homework. Now you have to find out why. I am not telling everything.

my last message was and is in response to the first message that started this thread. Now to the message uptop: to avoid any type of powdery mildew or other molds I've been successful@number one keeping my environment below 50 % relative humidity I suggest growing in an environment that is drier.


Man stop giving bad advice.

PM has less to do with humidity and more with poor air circulation. You need to learn more about VPD before you start telling people what is best. I've personally know people with grow rooms that feel like a sauna when you walk in there and they don't have one single issue with PM.

If you want healthy fast growing plants, contrary to what most believe, a relatively high humidity is better for your plants.

Don't believe me? Check out thread by serious growers (growers who do it for a living-grower who blow the grams per watt numbers out of the water). Each and every one of them suggest running temps around 80 degrees and humidity levels at around 75. DJM and Heath Robinson just to name a few. Do a search for "VPD" and you'll learn the truth.

Now go back to promoting your site and STOP giving bad advice!!!!
