New Grower Mephesto Group Grow: Scene 1

[davisgirl]

Well it's been 6 days, everyone is progressing along. I've done a couple of tops and more LST. Also tried FIMing one, pretty much a double miss I think.

GW1 - D33 (LST into a short spiral - see what that looks like)

GW2 - D25 (topped about 5 days ago, )
View attachment 997129

SC1 - D32 (so she's into pre-flower?)
View attachment 997132

SC2 - D24 (a likely FIM abortion - don't think I cut enough, who knows)

GT1 - D25

FE1 - D25 (topped 5 days go, been trying to open it up w/ LST - the 2 new center stalks - bend or keep straight?)

Anyway, things are okay - been adding more nutes (~800ppm) twice a week, they seem okay with it. SC1 is almost 5 weeks and into pre-flower - suggests the start of blooming nutes?

I think your ladies look really good! Some growers suggest holding off on bloom nutes until the stretch is done. I wonder if what they mean is to not stop veg nutes until the stretch is done.

I’m a noob so I don’t know. It seems counterintuitive to withhold bloom nutes while bud sites are developing. I fed GH flora series and went by their feed schedule, which slowly decreased veg nutes as bloom nutes increased.

Good luck and happy growing!

Well I'm concerned with FE1 - she's been stretching a bit and the new leafs (which I assume are the cola-containing stems) are a bit pale at the edge and oddly formed. A few other new leaves have a slight patterning to them.

• Watering after drying out significantly, around every 3rd day w/ CalMag, recharge, 1/3 Big Bloom and 1/3 Grow Big pH 6.2. Not adding the P containing Tiger Bloom yet - though they suggest adding beginning week 5, the light flip for photos.
• Soil pH is ~6.5
• There has been more direct fan on her this week.
• Lights were raised a few inches the other day
• Temp 20h/78-80F 4h/70-72F RH averages 55%. However outside temps have been all over the place (20F to 65F this week) and have made continuity difficult.

She's the only one effected thus far - I pH everything going in to ~6.2 etc...just not certain what this is or what needs doing.

Well in the absence of any new info, I've opted for the following:

• Since one of the things that went wrong this week was very high humidity at times (80%) - remove humidifier from tent, decreasing RH to 50's and stop water spray from humidifier/fan combo.
• Fan redirected off plants.
• After watering last night with the "normal" amount, I didn't see runoff as usual; pots still felt a bit light still. Watered again this afternoon with 1/2 normal volume (50% CalMag first, then 50% w/ nutes as suggested for week 5 from , but 1/3 concentration ~650ppm) pH to 6.0 - runoff seen on each pot.
• Increased overall ventilation (turning up in-line fan, added an additional intake on the side).
• Raised the lights just a couple more inches, adjusted intensity down just a tad (FE1 has stretched a lot in the past week, much bigger/taller).
• Rotated pot positions, orientation.

Well I'll be waiting to see how things progress tomorrow. As a group I do think they look a little happier, but who knows at this point.

Boy I’m stumped to what that is. Maybe take it to the infirmary? Or wait 24 hours and see if your improvements fixed it? Great job getting the environment under control.

Looks like toxicity to me with the curling. Maybe a lockout of mag on the third picture? You can see you have some burnt tips as well. There is little to no chance the 80% humidity hurt anything- I have several plants right now that are very fussy with nutrients and cant take nearly as much as there sisters.

Upon further review Im ditching the cal mag idea and going straight burn. Chartreuse is not a good color.

Looking through other grow post for Fantasmo, it seems common to battle balancing nutes with them. Overall the plant does look better this evening, but some tips are definitely burned now. I'll skip the next feeding, just go with CalMag and recharge AND I'll be double checking all pH levels with a more sensitive calibrated instrument.

How do measure soil ph?

 

[Dewey Matter]

Well it's only been 3 days, but I'm throwing up more pics - the nitrogen issues aside, everyone seems happier with their new light and heat/RH. Also everyone did just their LST re-bent and re-anchored.
SC1 D35

FE1 D28 - The extent of her damage - she was fun to top & LST

GW1 D36 - I keep pinning her to the ground, moving out branches, kind of fun.

So a few peeps have asked how I'm measuring soil pH - both in-soil measurement and less often now, run off. One thing I didn't notice until this mid-week is that they are drying out way faster than just a week ago. Several were very light this morning, with these 3 gal pots, I'll be watering everyone other day at this point. Just watered everyone again, as suggested just Big Bloom, CalMag, Recharge - plus 1/3 concentration of Tiger Bloom for the two heading into flower - no additional nitrogen (e.g. Grow Big). Everyone was watered to runoff and I took a quick pH reading of that ~6.5 (pooled readings - right now everyone drains onto 1 of 2 large rubber mats).

I do believe the VPD issues were stressing the plants, they were also drying out faster than I had anticipated and it was suggested that using something like Recharge the entire grow allowed for too much nitrogen uptake in sensitive plants, even at the lower concentrations I was using (I do have air pruned roots all over the bottom and sides of the pots). Without direct experience, I can't parcel out if all, any or other factors were the root cause - just try to keep the variables under scrutiny. We grow, we learn and I'm learning a lot on my first one - thanks for the assist.
