Hi, I am growing in a 4x4 tent and I was using a spider farmer 2000. I thought the buds weren’t getting big enough so I added another sf2000 light in the tent, I’ve been keeping it 18inches from the plant. I’m running a 20/4 light schedule. I have flushed the plants because I thought it was a nutrient lockout and it’s been a week now and no change. So I’m thinking it’s light burn? Yesterday I took away the other light that I added. I have noticed a little bit of green coming back into the plants and the ph levels are good. So my question is it to much light in a 4x4 tent with only 3 auto flowers. I had two sf2000 at 100 percent. Will my plants bounce back or is it to late…
Welcome to the forum! Definitely not light burn. Really need you to fill out a support ticket to sort this out. Looking like ph and/or nutrient issues.
What strain, Seed bank, or bag seed
Method: Soil w/salt, Organic soil,
Vessels: pot size
PH of Water, Solution, runoff (if Applicable)
PPM/TDS or EC of nutrient solution if applicable
Temps; Day, Night
Humidity; Day, Night
First of all, welcome to the forum. Great bunch of growers here and very knowledgeable. Friendly with it as well. You will love it here. Do the support ticket that Bobbydigital put up as it’s a great help. On a side note how much calmag are you giving. If you need to get someone’s attention just put @ in front of their user name and it will put a flag up next to their picture like @Oceanfly. Good luck on this
Welcome to the community !
Welcome to the forum. I agree with Davyg, looks more like calcium problems. Cal-mag!
High light levels make plants calcium-hungry. Cal mag is needed, but some nute burn. Would be good to know runoff numbers.
Hi again, thanks for the helpful input and welcoming me to the community. This is my first grow. I thought it was cal-mag deficiency so I got some and added it to it for about three days and so no improvement so I stopped. I’m using tap water from my sink so shouldn’t it have enough calcium and magnesium in it? Or is it to much light in the tent and the plants are using it all up?

I feed them around 6.1 ph of water

I took some better pictures,
Hi Davy’s, when I first started noticing problems I fed it for three days and saw no change so I stopped with the cal-mag. I didn’t know that led lights cause them to use more and it makes sense when I put in the second light at full power that’s when the problems started. So as of now I only have 1 sf2000 on and I added cal-mag to the feeding. I guess I’ll do this for the next week and see if it helps
Bump this to 6.5. Continue with the cal mag. Affected leaves will not improve. Will need to look to new growth for improvement.
I’m with @BobbyDigital on this. Your PH needs to come up as your locking out on calcium right now. The leds will increase your plants need for calmag as well. I had similar in my veg tent. Started foliar feeding while hitting the roots with PH 7.0 and calmag. Growth was really slow as well. Took about 10 days to show signs of improvement. Old leaves stayed the way they were but the new growth was amazing
