2 1000w hortilux. 10 flowering plants. 5 yellowing. 5 not.

All the same soil and same strain. And up until yesterday same nutes. I was forced to try a nitro boost on the 5 that are yellowing. Tomorrow I will rotate. Just wondering what are the chances I got a bad bulb they are brand new this grow. All 10 are heading into week 5 flower. All buds are developing equally how ever. Haven't tested ph run off yet but plan to next watering Just seems like this isn't the case as why I haven't already done it . I feed heavy.
I'm at 2100ppm currently.
sensei bloom A+B (advanced)
Silica and cal mag (general hydro)
Bud xl (h&g)
Tonight a foliar spray
Green magic (h&g)
Sometimes I'll add some fox farm soluble. Beastie blooms.

My plants have always thrived green till flush.. The light is my best guess they are all on the same side.

Thanks for idea ls in advance!
Plants are so big and dense the room is packed its hard to tell in photos.. Will upload if wanted /needed.

2100 PPM?

Thanks for this being your only input... Yes. Last feed was 1800ppm. Now what you have to under stand is that I'm not doubling down on base nutes. It's the additives that boost that number(plus 300 tap) so there's that. I push till I see tips slightly burn. Then back off.. I've yet to reach that point yet on this strain. My question how ever had nothing to do with that. Thanks

Im with him without a pic its a guess if its lights strain soil nutes .... lil more could be derived from a photo or 2 .
And test each pot >

I'm spraying the 5 incase it is a soil ph issue. That way I can provide while I treat the soil. My thinking anyways.

All it is a typical senescence looking yellowing on 5 and solid green on the other side.. All from same mother and same batch of soil. All on same water /feed schedule. All get fed from same mass batch of nutes. Only difference is the light they are under.. Yet there is a shott over lap of the two lights in the center. Pics can't help on this it's moderate ive just never seen it before. Just wondering if anyone else has noted lights effecting things like this.. But there is a most definite difference in coloring and sheen. No tips or ideas without pics? I'll post some tomorrow. Had to watch curse of oak island lol.

Yeah i will test each pot also. Such a pain. To do. Wish I was running my old Under current here..

Maybe try changing out the suspect bulb with an old one and see how they do? I have never heard of a bulb being bad in such a manner where it works but the spectrum is unsuitable for plant health.

Dude man me either! But it's the last common denominator. I do have a one grow hps bulb. Thanks for mentioning that. I'll put that in there and swap positions see if I can't levelize the crop at least! Other than that it's right where it should be. Rolling over 30 days tonight.

Here's the difference.

Yellowing side. All same strain. The one stretching is my old mother plant. It's also yellowing. And it gets a blend of. Both lights .

Green side. Production seems to be equally but I know there is a problem. Im reaching out to you guys! I have another light installed also. Hold up photo to follow.

A 400w hps for power outage back up generator times. Never intended on using it with the two 1000.

Man id stick a MH bulb in that 400 and get some extra UV, maybe a 10k bulb. So long as you can keep temps good.

That is odd. Do you water one side before the other or any other common variable?

Damn that's a great idea! I'll track down a mh tomorrow. Don't have any 400s on hand.

Yeah temps are completely in control. No worries on firing another bulb up.

I agitate as I go so assuming equal to each.
