Hey guys this has been going on for the last week, clawing bud leaves. Fan leaves are not affected at all. There is only 200 ppm left in the coco after flush and I’ve been feeding at around 130ppm. Growing in coco/clay pebbles 60/40. 1000w de on 400w mode room temp 76f humidity around 51% No fans blowing directly on plants so not wind burn and can’t be toxicity because there is only 200 ppm left in medium. Again only bud leaves drooping! Please save me! Thanks. HOG.

Have you checked for bugs in the soil or on the leaves?
there is no trace of bugs at all. I think that there was a build up of N from the cal mag+ And I didn’t taper off soon enough and it just didn’t need all that N 2 weeks in. Going to do a thorough flush tmz start from ground up I think. I’m just not sure how well I can come back from this now... hopefully things won’t taste to green..

Did you use heavy magnification when you checked for bugs? I couldn't see any bugs under a 30x loupe last summer so I thought I was fighting a nute deficiency and nothing was helping. Then the guy at the hydro shop told me it was from mites. Early on in a broad mite infestation looks just like your pics and those little bastards are tiny. Took a 60x loupe and very strained eyes to see them. I suggest a 100x mic just to make it easier. If it is mites, then you're right, it is a nutrient problem but it's being caused by their phytotoxins.

Broad Mites really show in the new growth, narrowing leaves, clawing, and as the poisoning advances, a knarled look in new growth. I already had a full blown infestation by the time I took these pics and thought I was still fighting a nute deficiency.

Even after I eradicated the mites the poisoning continued for some time since it lingers in the plant tissue. The damaged foliage never fully recovered but I had vigorous new growth again after enough poison dissipated.

It looks like an excess of something...maybe Nitrogen, although it usually gets a little droopy from a N overdose. The newer leaves are affected, so it is probably something that has changed recently. Sometimes a changing Ph level can lock or unlock nutrients that weren't affecting it before. As an example, you can pump a lot of nutrients into your growing medium, but if your Ph is much above 7, some of the water soluble nutrients change into a non absorbable form. When the Ph comes back into the proper range, all of the insoluble nutrients are suddenly available and could be too high of a level.
With that being said, when leaves start growing weird, I usually consider it an overdose of something. Deficiencies usually affect the fan leaves first. This is my general rule...by no means should it be interpreted as anything official!

I was going to say, this happening to new leaf growth is typically due to nitrogen toxicity. Cut back on the calcium/nitrogen and push magnesium, phosphorus and potassium. You really need to keep an eye on your additives. You'll find a lot of "stand alone" secondary/micronutrient additives are derived from nitrates

Yes sir I cut the nitrates a week ago now, some of the leaves are kinda recovering/praying again I’ll post up later. I’m just not sure they would recover at all tho after the burn?

You make a very good point. Ph going in 5.6 and out is 6.1, consistently.

There are no mites at all, but this IS valuable info man thanks for sharing.

It'll definitely affect the plants productivity, but I don't think it will be detrimental enough to consider scrapping the whole thing. A couple good high volume flushes followed by introduction of very light nitrogen/calcium and much heavier doses of sulfur, magnesium, phosphorus and potassium. Passing some beneficial bacteria and mycorrhizae will help break down residual nutrient buildup in those pots during those flushes/feedings
