Hey folks I bought an HLG 288 V2 double slated board about a year and a half ago. How would one know if they received a bad board? Or am I not doing a great job growing. My temps are at 81, RH at 55-60 (I know it’s not in the best VPD range) my lights were 22” away, at 22k lumens. The plant was in amended Fox Farm Ocean Forest, I didn’t use anything crazy. Just Compost tea, Fish Amino Acid, Silicate Root’s Calmag, Gro Kashi, Worm Castings, and Malted Barley Seed. The plant was not rootbound but tops were yellow with super purple stems and necrotic spots. I was having to give it double the dose of Cal -mag from TPS. Still wasn’t getting better. Starting using GE’s Maxicrop, which started to get better but not fully. Anyways was it me or did I get a bad board? I read an article on the boards saying there is a chance of getting a faulty board.

thank you dude, that encouraged me. I was growing duke Diamond’s c99 x c99 s1 (untested as well) But it should be an easier crop to grow. I did finish Jinxproof’s madcap which one of its parents is 9lb hammer. Which I’ll put up a photo of. I was just having a lot of problems with nutrients and even pH (7).

I have already culled it but here they are the last photos.

How big of pots are they in? How long did you veg for?

Honestly they just look hungry to me. How often were you giving it compost teas? What was in it?

Also, you shouldn't need to worry about your Ph in soil. I use Recharge, but theres lots of other similar products to give a boost of beneficials and food for them to eat, and they will help balance out any PH issues. I had some issues that looked more like straight up normal rusty cal mag def, and using Recharge fixed that. I've seen some other threads w people trying Dr Jimz Chicken Soup for the Soil. Same basic stuff in it plus some milk whey for food. I am guessing that is what the Gro Kashi is supposed to be doing but I have never used it.

I have a ten stage water filter, 1.5-2 cups of EWC and Bu’s Biodynamic compost, 1/4 cup of LaB , 2tbspn Kashi, 2tbspn Fish Amino Acid, 1/4 tsp Ful-Humix, 1tbsp Black Strap Molasses and silicate.

She was in veg for like 3 months, in 3 gallons However it wasn’t rootbound. I fed her Once a week with 1/3tsp per half gallon of the FAA, but I’m starting to think it wasn’t enough.top dressed once a month with worm castings.

I think the soil was properly aerated, I just bought some pumice, so I’ll be using that. I also read with Quantum Boards you don’t need to give as much water. Every time I watered, I made sure everything was wet. I also think this strain was very very finicky.

Sounds like you have your teas pretty dialed ;)

I'd chalk it up to a stubborn strain. I have one finishing up now that I couldn't keep up with no matter what I did. Ran it a total of 3 times, got better each time but its a sativa dom that I just couldn't get the feedings dialed in for. Gave up and popped some other beans instead.

man I’m trying. Lol. I will definitely be more intentional and have a plan with this next grow. I’ll be doing more research as well. Thanks for all your help and encouragement. It just sucks seeing your plant not doing well. Like it hurts to see it

i have been there, and feel your pain. it's all a learning process and like anything else sometimes you have to fail to know what not to do next time.

one of the reasons i get myself setup perpetual, so that I dont have to wait a full 8-10 weeks to try something different or make adjustments to the next round. i try to get new plants in every 2-3 weeks, and that lets me dial in and make adjustments to my process faster.

either way I just always try to make it better than last time. even when im disappointed and i think my shit sucks, I just ask a friend for a spliff of their 'top shelf' dispensary weed, and remember that at its worst, my herb is still light years better than that crap lol.

OK, so without knowing everything its a bit hard to tell, but potassium deficiency can look like calcium deficiency with the main difference being potassium starts from the tips and edges of the leaves and works its way in, whilst calcium looks more like random rusty spots.

Too much calcium will lock out potassium and phosphorous (purple, woody stems – P is also locked out by overwatering). Worm castings are usually a good source of Ca, Mg and K, but if you're adding Cal-Mag on top of this, that may be where you are going wrong. You say it didn't lead to any improvement, so I'm guessing the reason is because you had adequate Ca and Mg to begin with and then overdid it. Definitely those bud shots are showing a potassium deficiency. The early veg shots are more of an overall deficiency or possibly salt build-up.

I don't grow in soil, so I can't comment on the other nutrients you use.

So you had your 550 on full power at 22" and got 22K lux? If so i would check your meter. What you describe sounds a lot like light burn. And 22k lux is not right for full powered 550.

Edit : 550 or 240 double board?

it’s the 240 double board. I bought it a year and a half ago. It’s supposed to get up to at least 230 watts

Still seems a bit low. HLGs par map for the 240 kit says 500ppfd at 24", 800 at 18". 22k lux would be around 300 and change. Is it a phone app? Its probably measuring low. Try with a proper lux meter, they are cheap enough.
With soil and organic fertilizer it can sometimes be hard for the plant to keep up with led lights. Id use them more carefully, never lower until you can see healthy growth and stop lowerin when you start to see signs of unhealthy growth (very light coloring, interveinal bleaching and purple stems and petioles).
Im not too sure how calmag works in soil, if you need to ph and all.

After having bought the Dr Meter and comparing with the Light Meter app on my phone, tbh the phone app seems to be more accurate? I'm not really sure but it is definitely more sensitive and as I move around under my canopy the numbers seem to change with what I would expect. The Dr Meter seems like I have to move it further to get different readings. I kinda gave up for now and just take a basic reading and then just adjust based on how the plants respond.
