I'm having persistent leaf issues. They are browning and curling. From what I've looked at online so far it seems it's either a nitro deficiency or nute burn, but i've no idea which. I've been giving them plain RO water for 3 days trying to fix it, thinking it was nute burn.
You can't tell from these pics due to the grow lights, but the first plant is and always has been a deep rich green. The second is and always has been a much lighter green, although it's gotten just a bit lighter recently.
these first two are a Pure Power Plant from Nirvana. This just started with this plant.
This one is just some plant I found. It was a lot worse, with some leaves curling up and turning brown completely. I removed those leaves thinking they would just drain the plant and do no good.
Information about my grow.
I've been growing under 2x300w LED lights. I have a Pure Power Plant from Nirvana and another that I just happened to find. They are both about 2 months old. I'm growing in a 30/70 mix of perlite/coco coir. I've been watering daily with the General Hydroponics line of fertilizers (all 3 + calmag).I've been using 1/2 tsp floramicro, 1/2tsp Floragrow, 1/8tsp florabloom, and 1tsp calmag per gallon of water. During the first few weeks I also used rhizotonic. I've been using "Kelp me kelp you" from fox farms originally along with the fertilizer and now just in a foliar spray. I'm using RO water that tested from the jug at 16 ppm, ph'd to 5.8 and that is also the water I'm using for nutrient solution, ph'd after adding nutrients to 5.8. The plants are 3' under the grow lights and they automatically shut off for 6 hours a day. The ambient temperature is ranging from 72-78, usually it stays around 73-75. I have a small fan blowing air over the plants, between them and the lights.. it's enough to make the leaves move just a little bit. I have another fan ensuring air circulation throughout the room.
