Photo sensitive burn.

[Rusty Trichome]

Already looking,... but I don't know the Kelvin rating of my current bulb! I'm certain its not the 6.5k,... I do believe it's the 10K,... will this hurt anything? :wtf:

It's not that the HQI will necessarily hurt your plants, but it isn't at all optimal. Good for aquatic plants and animals, but not great for terrestrial plants. They run too hot, which means you can't get them close enough to promote healthy growth. Plus, they really are the wrong spectrum. The blue end of the spectrum for veg, red end for flower. 10,000k is a middle-of-the-road spectrum, often used to wash the blue from your fish tank. Gives more of a yellowish-green tint to the water, which some tank keepers prefer. (color-blindness...? IDK).

I wasn't planning on feeding or flowering for another couple months,... But I've learned that I over potted my plant,.... SEVERELY! (Clone straight into a 3 gallon pot) and of course there's a TON of problems associated with that.

Yup. Would have been handy info, but that isn't the cause of your lighting and nutrient problems...
You are likely to have late-stage ph issues, since you will have been in the same pot forever.

My recent problems have me thinking of letting the soil fully dry and repotting in a smaller 2ish gallon pot for the moment, to let the plant get more root bound in the remaining soil before expanding into new turf.....

No need to let the soil fully dry for transplant, just not too moist. :thumbsup: But regardless, at this point, it might cause more problems that it's worth. Shoving 3 gallons of shit (just a common phrase...don't get your panties in a wad) into a 2 gallon pot can damage roots and add another layer of stress. I'd ride out the error, and prevent it next time. :thumbsup:

Thanks,... With the MH and Ballast in the booth temps stayed in the 70-80's,.... 40%-50% RH,.... Guess my first practical test of the vents proved more than just a little inaccurate! (not sure I trust my thermometer any more IMHO :wtf: )

A fan-forced exhaust is almost always better than fan-forced intake.

I've got a drop tester,... not quite as accurate, but it's a ballpark right?

For clear liquids, sure.
Keep in mind with the drop testers, the result is color-coded. After you add nutrients or additives, it will skew the result. (red plus blue equals...9.2 ph? ... ) Likely not even in the ballpark. So do not depend on any ph readings, unless you are ph'ing a clear liquid. (water) This especially holds true if trying to ph the runoff. It doesn't work with the drops.

Question,... How do I add Perlite to an already potted plant?

Either wait till your next regular transplant, or, adjust watering quantities and frequency, or...
How much room is there between the top of the rootball, and the top of the pot? If there's enough room, lift the plant out and add either straight perlite or your potting mix with 50% perlite. But make sure to leave enough room in the pot for future watering and feedings.

As for the feeding,... I wasn't planning on it before flowering, but during flowering was thinking of the FF "recipe for success" blend, since if I repot it will be in FF Ocean forest.

When a mix say's it's pre-ferted, it's usually a minimum of nutrients provided to keep the plants alive. But this doesn't mean they will thrive. Miracle Grow Potting Mix says it will last, what, 4 months? (I think...been a while) But in actuality, after a month or so I was having to start 1/2 doses of Fox Farms nutrients. (hint, hint)

turned the fan up a notch and made sure it's mostly blasting on the pot,... Hopefully the soil will dry out quicker.:jointsmile:

I often change my fan angle and position in the growroom to get 'better' circulation, and avoid wind-burn.

If none of this helps, there's a link in my signature regarding a handy Bonsai re-vegging technique.
