The Strain - Gage Green Grape Stomper OG from clone

The Lights - (4) Kessil M350 (90W) (6) Kessil 150H (35W) (2) COB bars of CXA3070 AD Bin 3000K driven at 1.05mA

The Medium - Mix of FFOF and FFHF

Pots - 10G Smart Pots

Veg time - 8 Weeks after transplant from solo cups. Honestly, could have moved to 10s quicker.


I'm open to all discussion and tips. Happy to learn more, this is only my second run!

Oh - I've also bumped from 12/12 for 7 days, to 13/11 to now, I'm at 14/10. I'm using a 730nm flood to induce the sleep cycle, hoping to take advantage of a couple extra hours of light to make up for lacking coverage and saturation.

Doesn't look like a burn I just had the same problem and it was a Cal deficiency from a PH swing. (try to take one of those leaves off into better light and Ill be able to tell) A quick cal/mag foliar feed worked for me but then again you are in flower. I would suggest a slurry test with your soil to see what your ph is after a 30mins. If your ph is off correct it with a mild flush of water and 25% strength cal/mag. If your PH is on point then water with 10ml cal/mag per gal then go down to 5ml. We have similar set ups so I like your style!

This is going to sound blasphemous, but I don't have a pH meter. I'll get my hands on one tomorrow, should be able to rent one for a day or borrow from a friend. I'll check around now. How does flushing work in organic soil? Won't I be washing out what I have built up in the SS? Lights come on in an hour so I'll grab that pic in a bit and post. Glad you like it and I'm not totally crazy for trying something like this!

Oh man you gotta get a PH meter. With organics Ive heard you shouldn't have to PH but well wait for someone that knows more about that. Thats the point is to get some of those salts out of there so the soil isnt so acidic. My ph of my soil was about 5.5 which is way off and was locking all sorts of things out. After a few days it was back to normal.

Check out my set up. Im excited to see what you yield from yours as this is my first personal run.

So, after some research, what I'm thinking is that LED is really causing it to eat up the Cal/Mag, and I'm not sure how effective the topdress of Azomite I did at the start of flower was (I've read that it's best to mix it with soil *too late* or bubble it with some tea, which I'm doing). So, I've got a SST that I had sprouting that I just blended up, some fulvic, a touch of frass, some molasses and a few Tbsp of Azomite in the bubbler to cut for use of 12Gal of water. It's not concentrated in enough of anything to really hurt and they've always responded great to my SST, so I'm hoping this helps a little.

Hey man sorry to ask this cause its likely been stated already but how many watts are you running over what size of an area? In my opinion you probably just need to raise your lights. I have to dim my fixtures or raise them up a decent amount (24" or so) and sometimes I have to do both. They seem to do fine after getting used to the cobs after a week or 2 but those cobs are intense and some strains handle them better than others.

Edit: Damn I just saw you have videos that I haven't been watching. I'll check those out soon as I leave this hell hole that pays me for working

I think you're right. I definitely needed to raise my lights. I pulled em up a few inches, and used a little bit of these nutrient spikes my buddy has, as well as the tea I mentioned. I'll get in there today and get another video, but it looks like I was running into a bit of mineral deficiency.

Sorry, I missed replying to this. Right now, 5 Kessil H150 (35W) are up, 4 M350 (90W) and 2 140W COB bars. So, what's that, about 800 and change? For a 4x6 that could easily be 5x6-8 without losing much (have extra light at the sides with the lights too low, raise them a little and an extra 6in on each side is cake)
