Getting out of the ideas - VPD, nutrients or deficiency?

Verbaliststarted grow question 3y ago

I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

Curling new growth All of my new growth is curling a little bit. I dont think it's N toxicity, but it's also probably not heat because all of them look like this. Is it N toxicity or something else? Thankss

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

Plant health assessment (Leaf coloring and nutrition help)Sorry for bombarding you guys with questions, but it's getting serious now, right? Anyway, my leaves are getting funky colors and I do wonder, what is causing this? Is this normal? I have used the bloom nutes as in my diary once this week, rest was distilled watering.

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassium Outdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?
