Growers Error reminds me of
@GroErr .
Hope he is OK. It doesn't sound good. I learned a lot from him. Didn't chat with him much and didn't really know him but I did learn from him.
I brought up PH because I was thinking about your soil grows.
You mention in another post that growers in general have less problems in soil and I thought you mentioned some time in the past that you also had less trouble with soil.
Try to figure out why soil is working better.
Both soil and hydro should be able to deliver the nutes needed if everything is in good order.
I have a nice buzz from edibles and had to erase a bunch of stuff about the differences between a soil grow and a hydro grow with LED like I would know from having used LED one grow with soil LOL.
Hydro of any form is going to push the plant harder vs soil.
A quality soil will adjust the PH to it's needs.
These are two areas where soil and hydro are different IMO, there are others and if you can think of other differences that matter I would explore those also.
I'm not sure if the problem is that the plant needs something more in the form of nutes.
No joking below just my 2c that is not always worth 2c.
I followed the conversation between you, HB and
@lukio.
I remember lukio showing a pic of a plant that appeared to have a very minor nute burn around the edges of the leaf, turning a color that appeared white.
I agreed with HB when he suggested the problem was likely to much of something. I know the delivery of the message was not appealing.
If I go back further maybe 2 or 3 months I remember hybrid showing similar pictures with white edges except the extent of the damage was much heavier.
I'm feeling lukio may have had minor leaf damage from slightly to much of something and beginning to wonder if your case is too much of one or more nutrients.
I'm really not sure what your issue is just thinking you are pushing the plants hard to get the maximum yield.
Have you ever taken a plant with the minimum possible amount of quality LED light from start to harvest just to see the results in hydro or coco?
I think it would be a good experiment. Use the lights and the strain that you struggle with and see if you get LED deficiencies under low but healthy lighting. Just a thought.
I lied about what lights I run. The 4 in the middle of the room are HLG 600h, the 8 on the sides are hlg550s. It was only after purchasing the 600s did I realize they were too powerful for my room, and I have them hung about 33 inches from the tallest colas. The HLG 550s are hung about 26-27 inches away from the top cola. All lights are dimmed to 65%. this gives me roughly 650ppfd in a 2ft square from center of the light, and around 450ppfd out to the edges on all 3 trays. My current room temp at 80 degrees is my swing low, my swing high is around 83-84, I personally don't like it to get hotter than that. And for those of you who said that you can't grow good weed with LEDs. I'll note the tray I photoed here I averaged 1.25 lbs per plant with 6 plants in a 4x8 (and room in between each plant). Assuming I get the same numbers now. I'll pull 20lbs on 16 plants in a 4x15 area under 4 HLG 550s (I know I said 600s, but I raised them higher to keep the ppfd levels the same as the 550, ill be switching out the drivers next grow) 20lbs = 8960 grams. 480w at 65% = 312w x 4 = 1248w. 8960/1248 = 7.17 grams per watt.
