No.

This started 3 days ago as spots on the leave and spread to the out side of the leave.

Gave ferts yesterday. 1st time. Made sure it was alittle weak just to be save.

This is also showing up in another strain.

I'm worried. The plants are 3 weeks old. Ocean Forest is the soil.

Maybe boron deficiency?

I found this at another site. The pic's would not print but was the only thing that showed the color.


Boron (B) Micronutrient and Immobile element

Boron is important when dealing with maturation, pollen germination and seed production. As well as keeping calcium in soluble forms and keeping the stems, stalks, branches strong. Born keeps good color on the leaves and helps produce the plants structure. Boron also aids in cell division and protein formation.

Boron deficiencies will show up first in younger leaves (they may turn yellow), then moves up the plant. Boron deficiency can resemble calcium deficiency. Stunting, discolouration, possible death of the growing tips, bud abortion and development. The Roots will show a stunted with swollen short secondary roots, leaves distorted, sometimes bronzed or scorched. Tip of the shoot dies; stems and petioles are brittle. Boron deficiency plants are easy to tell, because of the spotting the leaves show like a strawberry mark and or splashes of the marking. Boron-deficiency symptoms first appear at the growing points. They also can show signs of newer growths turning gray and or dying, bud deformed, curling of the leaves which are often spotted and discolored. Newer growths appear to look like they are burnt. They can show signs of hollow stems along with yellowish to brownish color leaves. Dead (Necrotic) spots develop between leaf veins, as well as the leaves becoming thick. The leaves will wilt with necrotic and chlorotic spotting. Boron is poorly absorbed with low potassium content. First signs of the deficiency are abnormal growth tips. Having not enough boron can also invite troubles for fungus problems from the internal tissues to rot away, as well as the root hairs along with them being discolored. To avoid having a Boron deficiency try to keep the ph below 7 and to improve the moisture as well as retaining light soils.


Too much boron in your plants can produce a lot of problems. The leave tips turn yellow progressing inwards causing the plant to soon die slowly along with leaves dropping a lot.
Can show same signs as if a magnesium deficiency, but only happens on newer growths. Parts affected by a boron deficiency are: Growing points and young leaves.



Problems with Boron Being Locked out by PH troubles

Soil ph under 5.5 or over 6.8, sandy soil, soil with low organic matter and or lack of nitrogen.



Soil

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


Hydro and Soil less Mediums

Boron gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-5.0
Boron is absorbed best in Hydro and Soil less Mediums at ph levels of 5.0-6.0(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 boron deficiency.



Solution to fixing a Boron deficiency
One of the ways you can fix a boron deficiency is to either foliar spray or water regular. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!) Other nutrients that have boron in them are: Borax, Boric Acid, Colemanite, Sodium pentaborate, Sodium tetraborate, which are ALL fast absorption. Garden Manure, Bone Meal are both good boron supplements, but are slow/medium 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.

Those are much better pics Zep. The bigger plants actually look a bit like nute burn. I thought they could be a deficiency before but seeing these, I'm not so sure. What kind of fert did you give them? What strength? Did you check the Ph of the fert or the runoff? I would rule out boron though as it is an immobile nutrient, meaning it would show up in the young leaves first, not the old leaves.

As for the little ones, it kind of looks like pics of tobacco mosaic virus that annom showed. Are these clones from someplace or are they yours? I have never seen TMV in the flesh though (hopefully never) so I really can't say. Annom's pics are here: Shameless plug for my diagnoses page!

Be careful with the ferts, I use mine only about once per week at most.

Being careful with the frets. Wii be another week before I use them again.


ph may be 7.5, only have strips for now.Don't know how good they are.
Will have my Milwaukee ph meter working by the end of weekend.

The plants are looking better today. Cut the bad leaves off.

Now wait for time to pass. Hate waiting.

In soil I like to shoot for 6.5-6.9, with hydro you can go much lower, around 5.8.
