Need help, Please, Pics Pics

Hey guys this is my pineapple chunk plant.
She is 6 weeks into flowering now and i love her fat ass buds. But i have had a problem with the leaves for a pretty long time now. I am starting to notice its getting worse.

My temperature averages around 75 degrees and humidity around 40%.
I feed it like i feed all my other plants and all my passed plants that i grew. So any help is well appreciated, thank you. Peace

What is your nute schedule? Looks possibly like magnesium deficiency but I'll let someone more experienced confirm.

looks like a potassium deficiency

Yep ^^

I feed the ladies every other watering, but i guess its a potacium def. cuz that pic really shows it. Hey thank you for replying and helping me I really appreciate it. Peace

Hey thanks a lot man for puttin up the pic and everything for me, that was very kind of you to do. Ok so I use flora nova bloom, liquid koolbloom and grow.

The bloom is 4-8-7
The grow (for veg) is 7-4-10
The liquid koolbloom is 0-10-10
What do you think i should do? Maybe add more of the liquid koolbloom next feed. I am feeding them at full dose now so i dont know how im getting a deficiency. I guess its the way the plant is thats all. So thanks again and let me know what you think would be best for me to do. Peace

Just for informational purposes, here is the info that goes with the pic.


Potassium (K) - Mobile
Effects of Potassium on Cannabis Leaves
Spotting Potassium Deficiency

Older leaves, first tips and margins, then whole leaves turn dark yellow and die. Stems become weak and often brittle. Plants become susceptible to disease. K is usually present in soil, but locked in by high salinity. Internal temperature of foliage climbs, causing protein cells to burn and degrade. Excessive evaporation from leaf edges causes burning.

Healthy dark green foliage.
Leaves loose luster, weak scrawny branches.
Leaf margins turn rusty brown, curl up and dry.
Older leaves yellow and develop rust colored blotches.
Leaves curl up, rotting develops and old leaves drop.
Flowering retarded and greatly diminished.

Treating Deficiency
Treating Deficiency

Fertilize with comple N-P-K fertilizer. Use organic soluble potash mixed with water, however adjust the pH to 6.5 before application. Foliar feeding is not recommended.
Signs of Potassium Toxicity

It is difficult to diagnose. The absortion of Mg, Mn and sometimes Zn and Fe are slowed. When these nutrients are deficient P is often toxic!
Treating Toxicity

Flush growing medium with mild complete fertilizer.

Looks like a cal/mag issue to me, with the inter-veinal light green and rusty looking brown spots.
What's your medium and what's your ph?
The mg issue is causing the light green between veins and the rusty brown spots are almost always a calcium issue in my experience.
I grow in pro mix using GH Flora. Without using liquid cal/mag I usually wind up with plants looking just like yours.
PH needs to be in check, also!

I second this ^^^


I've had some K issues before, and I noticed it on the leaf fringes, somewhat uniformly up & down both sides of each leaf finger... and they would start at the very tips of each fringe, drying up & going crispy. Fringes also tipped upwards each time. Just doesn't look like your pics... compared to my previous issue.

Not that I have the credentials, but just thought I'd throw it in the mix anyway, and maybe ya'll can better educate me!

Since you're at @ 6 weeks, that's 42 days, isn't it normal for the plant to start "losing" some of the green at the end of flowering - usually it's N deficency i suppose, where we are talking about a K lack. Cause the last shot, those buds are looking sweet!

Moderate PH problems causing nutrient lockout.

This is a good thing though. Minor crises are opportunities to understand our plants better.

Just give it some blackstrap molasses. You'll be glad you did.

Are you reusing soil, got a hot mix, etc? hm probably need to add dolomite/lime to your mix?

Those two things will cover you on K, cal, mag, and pH swings.

Around the 3rd & 4th week the plants stop using so much Nitrogen & calcium & they start needing more magnesium, P & K . which is why most calmag users drop the calmag & use just epsom salts (magnesium ) & throw in a P,K boost . this seems more like the case in your plants . feed with some epsom salts & a P, K boost like your koolbloom . I use the powdered stuff not the liquid but i'm pretty sure it has the same ingredents ... just more water to make it soluble .

i don't know what medium your using but the PH is a major factor when it comes to nutrient uptake . just make sure your PH is in check for whatever medium is being used .



growem green & stay safe ...Dans
