Hindu Kush - double trouble


#122

I feed almost daily to runoff. Then Sunday nothing Monday flush.


#123

No water in between? N maybe feeding a bit hard. I misstated earlier, less like a deficiency more like toxicity


#124

A picture in natural light would help. I’m wondering if the root zone ph isn’t trending high enough to lockout some micros. Applying at 5.5 and runoff at 6.0 doesn’t exactly seem picture prefect. Something like manganese or a different micro could be locked out. Unfortunately I’m not that in tune with hydro levels.

@Ausgrow

It looks to be Nutrient Buren, But a better pic in natural light would be very helpful


#126

It’s been consistently at 2.1 in. 5.5-5.7ph. There are two plants and this is the smaller of the two. About 6weeks from germination


#127

What are you feeding them and how much…be honest ok…and what week of vegg are they in


#128

I feed them Cyco nutrient line grow a,b ryzofuel, b1 boost. Mammoth p microbials then top up to 2.1 ec with cal/mag. They have had 3/4 strength cal/mag twice then just what’s in the top up. I flush Monday, feed Wednesday, Thursday, Friday and Saturday then nothing Sunday. They each get 3-3.5L at a time with the flush taking about 12-14L


#129

They’re 5 weeks into veg. Here’s some more pictures


#130

Excess of potassium causes calmag deficiency. That’s my guess. Ease up on the feeding. But let someone else confirm it. Or excess of phosphorus. One or the other.

@Ausgrow

I agree with @DoobieNoobie to a point. To much feeding once a week is fine any more than that is over kill and will surely cause problems as you can see.

Manganese (Mn) Micronutrient and Immobile Element

Manganese_Deficiency_in_Marijuana_Plants

Manganese

Manganese Helps enzymes break down for chlorophyll and photosynthesis production,
as well as it works with plant enzymes to reduce nitrates before producing proteins.

Having plants that are deficient in manganese can turn the young leaves into
spotted (mottled) yellow and or brown areas on young leaves. Dead (Necrotic)
yellow spots form on top leaves, while the lower older leaves will or may have
gray specks and or spots. Symptoms can include yellowing of leaves while the
leaf veins can stay green. Can also produce a chequered effect. As the plant
gets newer growths the plant will seem to grow away from the problem, that’s
why the younger leaves may be unaffected. On the top of the leaves, brown spots
can appear. While the severe areas of the leaves turn brown and wither.
Parts Affected by a Manganese deficiency are: Young leaves.

Too much Manganese in the soil will cause an iron deficiency. The blotchy leaf
tissue is caused by not enough chlorophyll synthesis. Your plants will seem to
have very weak vigor caused by the excessive amount of manganese.

Problems with Manganese being locked out by PH troubles

Soil ph of over 6.5, High iron soils, Low nitrogen Soils, Dry weather
and compacted soil.

Soil

Manganese gets locked out of soil growing at ph levels of 2.0-5.0
Manganese is absorbed best in soil at a ph level of 5.5-6.5 (Wouldn’t recommend
having a soil ph of over 7.0 in soil) anything out of the ranges listed will
contribute to a Manganese Deficiency.

Hydro and Soil less Mediums

Manganese gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-4.5
Manganese is absorbed best in Hydro and Soil less Mediums at ph levels of 5.0-5.6
(Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range
for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed
will contribute to a manganese deficiency.

Solution to fixing a Manganese deficiency
Foliar feed with any chemical fertilizer containing Mn., or mix with water and water
your plants with it. Any Chemical/Organic nutrients that have Manganese in them will
fix a Manganese deficiency. (Only mixing at ½ strength when using chemical nutrients
or it will cause nutrient burn!) Other nutrients that have Manganese in them are:
Manganese chelate, Manganese carbonate, Manganese chloride, Manganese dioxide,
Manganese oxide, Manganese sulfate, which are all fast absorption. Garden Manure,
Greenssand are both good sources of manganese and are medium/ slow absorption.

Now if you added to much chemical nutrients and or organics,( which is hard to burn
your plants when using organics) You need to Flush the soil with plain water. You need
to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon
pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good
enough to get rid of excessive nutrients.

@Ausgrow any change in the ladies? N thanks fellas.


#133

Not yet. I’m still not sure how to treat it. It really doesn’t look like the problem in the pictures above. I’m going to try to get some Mn anyway and give it a go.


#134

Thanks for the info. Bookmark worthy! :+1:


#135

Thanks for the info. I’ll go out today and try to find some Mn.


#136

A bit of a flush, a haircut, some monster cropping and a flip to 12/12. Not a bad night out for the ladies.


#137

Youre gonna have that net packed to the gills! Damn fine work


#138

Good prediction @PurpNGold74 here they are today. Both are monster cropped to the net. They are 6 days since flip.


#139

Looking good! 93864317-2349-4A6B-83D9-2624536EE36E


#140

Wow they filled that out nicely! Beautiful girls.


#141

Hahaha a day later and they have. Ur gonna need a bigger net :joy::joy::joy::joy:
