Looks to me exactly like the hear stress I saw in my outdoor lady last year.. 30 or higher is just too hot with them.. Especially if the humidity gets lower. A fellow grower Mrs_larimar turned on to this Chart.. http://www.just4growers.com/media/23631/vpd_2degree.gif .. lovely visual representation of what the plants need are.

If you have issues reading the chart... It basically says optimum Humidity of 60-52.5 rh is ideal for healthy vegetation in late flower with a Temperature range of 30 degrees Celsius. Try to move it to a more shaded area that still gets an average amount of sun.. Again it's a wonderful chart and I hope this helps.

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?

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should. 1. Are these really signs of nutrient deficiencies? 2. Which nutrients are missing? 2.1. My guess is P, N and/or Mag, Cal. Is that a good guess? 3. Is BioGrow a good choice to address these deficiencies now?

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.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!
