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?

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?

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.

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?
