Im not 100 percent sure myself. I never had these problems under t5s. Been feeding at 6.1-6.4 ph. I love these lm301 leds for flower but not anything else. Im going back to t5s.

In my experience, the LEDs need to be turned way down for seedlings and teenage plants. For example, im running around 15-20 Watts over my clones and mothers.

Yes. I bought dimmers for my 65 watt boards. I dont have them plugged into wattage meters although i have one. Im dimmed atleast halfway down i would say. When i first started using them i didnt have dimmers and immediately noticed leaves twisting and trying to hide from the light.

Think im gonna plug in my wattage meter and see where im at. I will probably start at 15 watts and go from there. Thanks for the tip.

Hope that helps. As the plants get bigger, they can use more photons.

I sprout my seeds and veg directly under my LED, keep the plants anywhere from 14-24 inches away (I just eyeball it) and have never had an issue. Itās a powerful light, too, and canāt be dimmed. In the spring, Iāll sprout and veg outside in full sun, never had an issue, either. Just FYI. Not too sure why any plant would need LESS light.

Oh. You can definitely give too much light too seedlings and even plants in flower. Seen it firsthand on multiple occasions. Different leds output different light intensities at the same wattage. Im guessing your not using bright white high efficient leds like the lm301h/b diodes used in popular modern style quantum board fixtures.

Legit like old skool T5 light??
Iām curious if we all ājumped the sharkā with all the amazing tech, and T5ās are very much still viable. Iāll have to do some reading, theyāre definitely cooler runners bwuahahah

@ReikoX. I just realised the temps have dropped considerably in the last week and my tents are in a unheated basement. I forgot to turn my heater on in the tent. Im thinking that may have something to do with it. I also noticed a leaf about midway up on one of the plants starting to canoe. I really need to find a reliable piece of literature to help to understand nutrient uptake. Thats my new goal. Learn all about how plants uptake nutrients and what factors effect it. Im tired of always playing guessing games. Lol

Teaming with Nutrients by Jeff Lowenfel covers it. Its probably one of the more tedious of his texts to read.

Okay. Hes more of a organic grower is he not. Im assuming so because i know he authored teaming with microbes. Would that book still apply to inorganic chelated nutrients like i am using?

He is a soil guy, but once the microbes make the nutrients into an plant usable form, it is the same chemistry.

Right on. Appreciate your time. Gonna order it and see if i can find the time to read it. Lol
The lights are Apache ATās, one 600, two 200ās. 3:2 red/white. I honestly couldnāt tell you any more info than that. Like everything else, I researched the fuck out of them and then forgot everything once I got them and realized theyāre great lights. Itās just like every job Iāve ever had or anything else: Iām intimately knowledgeable about what I need to know to do my job well, but the second I quit/get fired, I forget everything. Itās kind of an issue.
Re: soil, nutrients etc: If you have the money, Iād just mix up a big batch of organic soil and call it a day. It really isnāt even all that expensive unless youāre mixing up a ton and it eliminates any kind of guess-work. I like Cootās mix, but there are plenty out there.

Been there and done that on the organic water only mixes. Not my thing. Im only having issues with seedlings and i didnt have issues until i switched to these quantum boards. You paid 2500 bucks for a grow light that only advertises 4x4 coverage? Thats fucken insane man.

Yeah, it was a lot of money for sure. But at the time, I had it to spend. And I was working my ass off all the time, no desire to spend what little free time I had building my own light. That was five years ago, too, when it seemed like there was more confusion about ādo it yourselfā LEDās than there is now. Too many differing opinions made me go,āFuck it, Iām just gonna shell out some doughā¦ā When it comes time to buy another, in five or six years, Iāll probably make my own.
The AT 600 actually covers 5 x 5. Still not great, but good enough.

Plants are already come out of it. Upped the cal/mag feed yesterday, lowered the lights down to 18w, and got the heater going. Its about time to up pot to 5x5s before their final 3 gallon fabric pots.
