[Maybach4]

Hello there I am new to led lights never had any problems with hps in the past I have a 3x3 meter room and using 6 lummiblack 720 w lights and 3 adjustawatt retro.
So 9 lights in total all set down to 250 watts I’ve got short plants that are not growing , purple woody stems and discolored fan leaves I just can’t work it out can someone shed some light on this for me please

Mount the light as high as possible. Set it as dim as possible. When the leaves look like they are praying right before lights out turn them up.

You have damage down low on the plants. Not a light issue. That's a nute/rooting issue. They look like cuts/clones. Lights will be a secondary issue because the plants are stressed.

No,,,, you're working with a much more efficient and aggressive light that can be much more demanding of the plant, nutrients as your environmental conditions get easier to manage. You don't have to run them hard. 250w on a quality LED is a whole lot more light energy than the old tech would put out with much greater penetration at the same power draw. It took me awhile to adjust from old tech to the LED's. And when that was done it was a great day when I hauled all the old lighting to the junkyard.

This is one of my simple tents. It's a 2 x 4 with two HLG 350R's bolted together for a ceiling of light. It's a hybrid dirt grow with 75% soil, 25% coco using Gaia Green, worm castings, DE and a couple of other amendments. Nothing fancy at all. A KISS grow. Last week when these pics were taken the plants were 3 weeks old to the day. Lights were 27" or so off the top of the plants on there lowest setting which was 180w draw total between the two lights. For a par level of 350. That put me a tad high on DLI and the edge of good when it came to VPD factoring in leaf temp with 80f and 65%rh in the tent. It's just a new balancing act when you go with quality LED's and ride the wave. I've now taken some lower leaves off and topped them. And there going to stay short squatty indicas. They do taco the leaves when I first open the tent. But go back to relaxed and praying after a bit. Damned hybrid fufu weed is getting stranger by the year.

Your just going to need to make adjustments...
