Hey man! Don't spray with your lights on indoors and outdoors during daytime when direct sunlight hits your plants, also foliar feed is best applied when the lights turn on/sunset or when they are about to get off/sundown, at this time the plants will absorb the most of it, also i never had nute burn from folair feed, maybe you got light burn because the water sprayed on your plants acted like a lense. Also at this point of flower you shouldn't foliar spray, i personally do it till week 4 of flower (grow phase sprays throughout whole VEG till end of week 1 flower, 2-4 week of flower i also foliar spray but with bloom fertilizers- also organic, the ones i use are BioTabs BoomBoom Spray (1x week) and Plagron Alge Grow (daily) for the growth phase and Plagron Algae Bloom (daily) & Sugar Royal (2x week) for the flowering phase- works great!
Hello @Spacegenetics ! The nutrient burn is a different thing from light burn caused by spraying. I make teas more or less the way i make a regular tea to drink. I am bring some water at around 70 celcius and i use 1 tbsp/L of water, let it cool and spray. I don't want to go over 70 because i want to keep as many thermo sensitive compounds i can but i also don't go under 70 because i want to extract as much as i can.Most of the times i use kelp but i also use some times nettle or dehydrated aloe vera. If you don't want to use heat at all you can just bubble it for one day. I tried both ways and they work fine. These teas will not burn your plants and they will give them a lot of exotic compounds like hormones and other stuff. If you don't want to make your own you can buy them. Some decent stuff is alg-a-mic and .active vera from bio bizz and from GHE urtica and bio weed. I usually spray after any kind of training and plants come back in matter of hours.Happy growing ! :facepunch:
DO NOT spray your foliage. Usage your humidity to help you leaves. Even when you grow outdoors it is recommended that you gently shake as much water off of the plant as you can. If you are not able to sustain a good humidity in your grow area, try using a humidifier. I have also been known to mist the upper area above the plants insurance I am not misting water on the leaves. Also to further help your leave and plant in general; add 2 tablespoons of coffee grounds to the top of your soil. This will naturally add: calcium, nitrogen, magnesium, phosphorus and potassium to your plant.
If you look at the first picture you will see the thinning of the leaves. Yes thin long leave are indicators of a plant being Sativa or Sativa dominant, but near you stem of the leaf it should be thicker and more lustrous. The thinning is a lack of nutrients your plant needs.
All in all good job.
