Discolored leaves, rust spots, and burnt tips

SilverSlapdickstarted grow question 2 years ago

Began with burnt tips, followed by rust spots on upper leaves. Then top leaves of new flowers came in yellow, followed by bottom leaves developing gross pale spots. Not sure why, please refer to my super soil recipe as well as the one feeding I did in week 5. Underfed, pests, ph?

i did look into your supersoil recipe and all i have to say is you are way over with nitrogen and with phosporus and not enough potassium at all.

Thanks @GanjaReaper. First grow in this soil, and my oscillating ac infinity is on 24/7 @ speed 6. Before planting I added a bunch of DTE crab meal, I’m guessing I should add more for cal and mag? Thanks again

Hi Jlimp, Thoose brown spots can be eighter Calcium deficiency or a rust funges, i think that in your case it is a Calcium deficiency. I also spot some Magnesium shortage. Make sure you add some and i think you will be fine. Just don't throw all kind of nutrients extra on it lol. Is this the first or second grow on the same soil? And how many hours a day is your fan running and how fast? Good luck growing :)

The lower leaves look like what happens with PH being out of range. So I am guessing the upper is a deficiency from the plant not being able to uptake nutrients due to PH.

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.

Nutrient lockout or deficiency Die unter Planze im Bild ist seit ein paar Tagen hell obwohl ich letztes mal schon mehr gedüngt hab. Habe mit EC 1.5 / Ph 6.2 gegossen. Im runoff kam Ec von 3.5 raus, es war aber nur sehr wenig runoff deswegen find ich 3.5 eigentlich in ordnung. Blatt spitzen sind aber auffällig.

Plantule aux feuilles vert clair. Engrais organique et fibre de coco.La plantule s'est bien développée, mais ses petites feuilles sont encore pâles. J'ai utilisé la dose recommandée, puis légèrement augmentée au second arrosage, sans amélioration. Dois-je ajouter plus d'azote ou passer au stade suivant de nutrition ? J'utilise l'engrais organique.

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Leaves burned after spraying a cocktail To repel aphids I sprayed garlic infused in alcohol with water, already did this few times without side effects. But this time I added several drops of tea tree essential oil. Is it possible that the essential oil has burned the leaves so much or is this some nutrient deficiency?

Bio Grow burn vs Bio Grow boost Hi, it seems like she keeps getting nute burns as soon as i give her Bio Grow, even at half dosage (1ml/L). She has only 10 more days of veg and i wanted to boost her, what if i stop giving Bio Grow altogether until flowering? Is the tradeoff worth it? No burn but less growing?
