What's wrong with this plant?

I noticed some funny looking stuff starting to form on a few leaves. Im not sure if its heat burn from my light or maybe nute burn? It's only on a few leaves.

This is a Skunk / White widow clone i got from a friend. I use GoBox for nutes but i only use it 2x times a week and about 1/2 of the dose, Shes under 24 hours of 400 HPS temp says around 75 and drops between 70-75 at night. I did have a little heat issue last week which i resolved by rising my light and adding a 6" Inline fan.

Im pretty sure it's related to the light/temp but I'm unsure because its not all the top of the plant (closet to the light) & The other clone which is a little taller does not have any signs of this.

Rep for anyone who can help with this issue.

Potassium (K):
a.k.a. potash, this nutrient is key for the usage of carbs/sugars. This is key for sturdy/thick stems, small bushy plants and disease resistance. Its needed for all stages of plant growth, especially bud formation.

Abundance: this is pretty rare to notice, excess potassium usually isnt absorbed by the plants but can mess with levels of magnesium, manganese zinc and iron. This in turn leads to salt damage acid fluctuations and possibly a calcium deficiency

Deficiency: this has yellowing of leaves, from outside in, but with a dark green center vein, and curling of leaf tips, this is mistakenly diagnosed as nitrogen def or iron def a LOT. Stems and branches will be weak, easily broken. the plant may also stretch. *too much sodium (NA) can cause a potassium deficiency.




Just taking a guess, kinda has the same pattern but tips seem to of gotten darker in yours. Were they always that dark when the issue happened or started yellow?

Only half the dose 2 times a week? Why cut it in half? That leads to deficiencies to which looks like your experiencing now.

Also there is no nutes by gobox. Theres a gobox system that has a variety of nutes is that what your talking about?

Yeah that's what im talking about as far as the nutes go. The reason for only 1/2 if because i got nuts burn on a few plants at full strength. I started to use a "tea" my local hyrdo sells some maybe it will fix the issue.

I hope it does, its nice little plant. Hate to see the problem progress. The hardest part is waiting to see what happens, I know it sucks. Good rule of thumb is to flush the plant out first. Get rid of anything excess in there, and doing more things to it isnt the best. The tea should have some extra K in it to add, and dont half nutes if anything give it 3/4 taking it down to half like i stated above can lead to issues such as this.

Also sometimes you have to increase the nutes gradually to its full dose. Of course do what your comfortable with but just giving half is gonna give you more problems up ahead when it gets bigger and requires more nutrients.

Pic one looks good, pics 2 and 3, look like same leaf.
Is this only on one leaf?
If so, any chance you splashed nutes on that corner?

Thats what gro thought too, but look at the leaves to the side and above it, how they are turning white between the veins. Thats why I thought it might be a K def. Or another type of Def.

She looked like this when i brought her home, Had crystals all over it and was in the beginning stages of flowering .. After about 2 weeks she started to veg again under 24 hours of HPS 400watts

that's normal for re vegging clones. the plus is they will give you more branches than a regular clone. Once they take off.:clap:

I thought it already took off lol , Should i expect even more growth ? Also do you think it would be ok to take a few clones as the plant got really bushy.
