Roc Bud autos Day 25: Environment questions

[BoCoGrow]

Hi there,

Some details, then some observations, and then my questions:

• Growers Choice e-680 light, currently at 100% intensity, roughly 690W power draw, 670 PPFD at 30" above canopy
• 4x4 grow tent
• OF in 3 gal fabric pots
• Temps and RH when lights on at 82F and 60-70% RH
• Temps and RH when lights out at 73F and 60-70% RH

Here is a pic of the bigger of the two Roc Bud Inc freebies (strains unknown) today which is day 25 since sprout:

OBSERVATIONS:

Observation 1: ever since moving to 100% intensity, about 1-2 hours before lights out, the plant gets crazy droopy. I don't mean that it stops praying, I don't mean the leaves are no longer horizontal, I mean it looks like it is dying. This pic was taken a few minutes after the lights came back on so it has recovered dramatically.

Observation 2: I had some purple leaf stems during the seedling stage but they went away. Last night, and as you can see in the pic, the red/purple stems came back fierce. Those red stems weren't there yesterday. Interestingly (to me, maybe not to you) all of the purple stems are on fan leaves, the branches remain green.

Observation 3: When I water, I give each plant 6 cups. They can almost take 6 cups per day now.

Observation 4: The bud development doesn't seem to have increased over the last day or two.

QUESTIONS:

Question 1: Are they suffering from light/heat intensity, and should I dial the light back to 80%? That will lower the temps, but the PPFD will drop to the high 400s.

Question 2: At this stage, should I be dropping the temps and RH since some bud development has started? \

I'm waiting on the Build-a-Flower top dress kit as well as barley straw mulch, which I will apply upon arrival, but appreciate any other thoughts or feedback if I need to be shifting the routine at this point.

I have a friend that has this problem sometimes. I think the plant is ahead of the root system. I hope someone else has an answer that can help

Leaves droop and recover often. Usually if in need of water or just after having been watered. The plant looks great for 25 days old!

If that grow light is truly 690 watts from the wall in a 4 x 4? I'd stay at least 32-34 inches away, possibly more.

At 25 days old 55-60% RH is probably fine........But soon u will want it a bit lower, maybe 45 to 50% RH after 5 weeks (35 days or so).

Lookin good. Buds will start packin n stackin in 10 days......

Are the leaves droopy but maintaining a sense of turgidity in them? Do they look great but by the end of the day start slumping all around the top of the plant.

You are hitting your DLI or daily light intregal. Google DLI calculator & from your lights specs you will be able to raise/dim your light.
