Mephisto Genetics Mephisto Genetics in 2x2x4 under LED

UPDATE

Day 35

She's still on the same reservoir nutes at 550 ppm / 1.1 EC, most of which is just MegaCrop v1 and a bit of Epsom (max 30 ppms) and 70 ppms of tap water.

Light is still dimmed to just 60Watts and it's placed about 54 cm / 21.2 inches from the tallest top. Next week I receive PAR meter (SQ-520) so I'll be playing around with the light a bit.

Some pics from today...

As always, any input or comment is appreaciated.

UPDATE

Yesterday was day 41 for this little Mephisto beauty ("24 carat x 3 bears og" ). I'm loving her speed and size and her resilience to LST. I wanted a fast and short plant and I think that's what I'll get and I feel those nugz will be really nice and fat regardless of her size!

Seeing some bottom leaves yellowing since mid past week and buds forming, yesteday I refilled my reservoir and I decided to increase MC... so now my total EC is 1.2 / 617 ppm (514 MC1, 70 tap, 33 epsom), ph 6.06... today the pH of the reservoir is at 6.29, which i will let like this for a couple of days and then bring back down to 6.0.
Last week I added a bit of Bud Explosion after seeing buds starting to form but a couple days after it got some Ca def symptoms, so assuming this could be due to excess K I've decided to not give more BE right now. Might not have really been the BE's fault but low RH again, so I increased RH and will wait a week before even considering adding BE again. I'm also in the fence about keeping the Epsoms which can also cause Ca def is there too much Mg.

Oh, and I got a new SQ-520 PAR meter and it turns out I've been working with a DLI around 14-24 with readings of 200 ppfd at pot surface level and 330 at tallest top. So today I adjusted lamp height (still at 60 Watts) to get 300 ppfd at pot surface... so now I'm getting 517-550 at tallest tops... thus i'm now in a DLI between 20 and 40. If it proves to be too much, Ill just reduce photoperiod form 20/4 to 18/6 and remain ina DLI range betwer 19-35.
@damien50 @Mañ'O'Green any thoughts in this regard? I assume I'll have to be very observant of the plant from today since the more light should make her use more nutes... maybe i'll also have to increase EC soon?

Here are some pics from yesterday:

Any how, pretty happy with this freebie strain. Since it isn't really occupying much space (which i was hoping would be the case) I might put another Mephisto seed to germinate soon and participate in the Wellies challenge... now I just have to choose which to soak... @St. Tom which would you choose:

Deez Nuggs F1

Mango Smile F4

White Chem F1

Super Orange Haze F4

Hubbabubbahaze F4

I wouldn't go with a haze strain in a welly so either of the other 2 bro and Nice job

Looking great pal

Looking great pal

Thanks! Let's hope having reduced the light distance so much doesn't hit her too hard! Just passed from 14-24 DLI to 20-40 DLI

Hopefully she laps it up in flower

...laps it up ...

Thanks for the good energy and for a new phrasal verb for my list! English is not my first language so i really appreciate you using such expresions!

Quick Pic Update...

Day 43: got RH above 60 % and plant seems to like it... not so many droopy leaves anymore.

Quick Pic Update...

Day 44: Yesterday, a couple hours after lights on.

And these two pics from today... showing yellowing and light brown blotches at the bottom leaves, and plant drooping 3 hours before lights off.
