Is this light burn?
savethehumansehstarted grow question 4 years ago
I am pretty sure it is led light scald but just thought id try to verify. I have a new 650w Hortibloom light bar and have been running it between 400w and 650w at the top of the tent.
I'm guessing 650w, even at the top... is too much?
They are in soil, and I'm using gaia green

Yeah pretty sure that is light burn . I had the same problem last grow and stressed them out causing one to hermi. Even with my 500w quantum board at 32 inches above it was too much ppf.
PAR meters are expensive so if you want a cheaper alternative check out the MIGRO video on YouTube . He converts a lux meter into PAR. I now use a lux meter to give them optimal light instead of just guessing.
But saying that It could be potassium defeincy. That can look similar to light burn. 🤷

Bio Grow burn vs Bio Grow boostHi, 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 cocktailTo 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.

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.

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!

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?
