Pre-grow notes:
Soak in shot glass 24-48hr
Germinate in paper towel with seaweed extract
Keep dome on and spray to keep humid until cotyledons emerge and cast off shell
Grow directly in 3 gal pots
After 25-30 days add dry amendments
1/6 Day 4 watered with hose
1/7 Day 5 watered with spray (contains seaweed extract)
1/8 Day 6 I think there is too much perlite in the soil and it dries quickly
sprayed soil in the AM
might consider transplanting after 20-30 days?
1/9 Day 7 sprayed soil in the AM
1/10 Day 8 dripped a circle of water around the seedling
1/11 Day 9 watered similarly in the evening, looked dry
1/12 Day 10 testing raising humidity threshold for fans, 69 to 73%
1/13 Day 11 Watered lightly early AM, seaweed extract + pH'd H2O
1/14 Day 12 Raised pots to be closer to lights and canopy of Purple Punch
1/15 Day 13 Watered moderately early AM, seaweed extract + pH'd H2O.
Raised lights a bit
1/17 Day 15 #1 looks a bit ragged, is leaning over
Watered them all, moved fans, moved pots
1/18 Day 16 Watered lightly in PM
1/19 Day 17 Lowered humidity threshold to 65%. Aiming for VPD of 0.8-1
1/20 Day 18 #1 is looking better! Stem was purple but now turning green
1/21 Day 19 Soil still moist
1/22 Day 20 Watered after lights on
#3 looks pretty stunted while 1 and 2 are growing quite well
1/24 Day 22 Watered thoroughly in AM before lights off
#2 has a little leaf clawing going on now. Underwatered? It's been a day and half and the soil is very very dry
Began LST with garden stakes
1/25 Day 23 Adjusted LST
1/26 Day 24 Topfed with "Veg amendement" as indicated
Watered thoroughly in AM
1/29 Day 26 Watered in PM once lights back on
Half a dozen leaves removed
Adjusted LST, removed stakes and replaced with wires
1/30 Day 72 Sprayed topsoil with water and then watered somewhat lightly
Adjusted LST, snipped a few leaves
Put in new humidifier, it's great!
2/1 Day 29 Sprayed topsoil, then watered in two rounds after lights on in PM
Light defoliation
2/2 Day 30 Wow, plants look very good today!
Planning to deploy AC Infinity self watering pots today in preparation for being gone for ~48hrs
2/3 Day 31 light watering before going to NYC
2/5 Day 33 made 15 gallons of new water. added 12 g of yuca extract, 15 ml of seaweed extract, and two and a half tablespoons Epsom salt. light watering of the top, but filled the self watering basins.
#1 was almost empty
#2 mostly full?
#3 mostly empty
raised light to 60%
refilled
2/6 Day 34 light defoliation of the lower portions of the stems
2/7 Day 35 adjusted LST
raised light to 70%
2/9 Day 37 Self watering dish had a thin film on the water surface, so I emptied all of them, cleaned them, and made new pH 6.5-6 water and just used that. Next time if I need to add anything I will add to the watering can instead.
Trimed a few leaves
2/10 Day 38 Raised light to 100%. Having heat issues, bringing VPD to 1.4-5ish
Cranked up humidifier to counteract, VPD stabilizing around 1.2
2/11 Day 39 Refilled bases
2/13 Day 41 Top fed with Second feeding. Spray moistened top and watered after 5 min
Defoliated, did slight pruning on #1, none on #2, significant on #3
Adjusted LST for #1, removed from #2, removed most from #3
Refilled bases
2/14 Day 42 Light spray of topsoil to help with feeding
2/18 Day 46 Cleaned and refilled base
2/19 Day 47 #2 is looking a bit unhappy, lighter colored leaves and some spots
Made pH 6.2 water
Soil pH seems to be ~7ish
Watered top to try to lower
2/21 Day 49 Watered top
Removed remaining LST bindings
#2 looking a little worse. Hope it's a lockout and nothing more serious. May consider a compost tea?
Measured soil pH, yikes it's high, 7.3-7.7. Will watering with pH 6-6.2 be enough to lower it? That might explain the sickening look in #2
2/23 Day 51 Made new pH 5.9 water and flooded each plant to try to bring down pH
2/24 Day 52 Away until 2/26
2/27 Day 55 Bases were dry or almost dry. Refilled with 6.2 water
Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?
First, do not overpay for an acid or base to use in this way... It should be cheap... and as long as it doesn't cause a precipitate or otherwise fuck with nutrients, it's going to wrok as well as any other acid/base. People who think the acid you use impacts how much pH can swing or whether it is a temporary change are confused about reality... The reality is, any unbuffered nutrient products will liekly have pH swings -- this is a sign of a shit-ass manufacturer that doens't really know what they are doing, if it occurs.. it is not the fault of the particular acid used. Anything unbuffered will be a risk to swing in pH for absolutely silly reasons that are easily avoidable. If you experience wild pH swings, buy better fertilizer, imho. fwiw, this particular context does not seem to meet that threshold.. this seems like an easy fix.
3 gallon jug of white distilled vinegar is hard to beat, and more uses around house, too. Get some 3mL pipettes for easy measuring. you might need 1-3mL per gallon. (maybe larger pippette or measuring cup, if you deal in larger volumes)
Maybe a little extra runoff will speed up the process of shifting the pH, but you don't want to leech your soil of nutrients too much, either... If no major issue, i'd just give enough for a little extra runoff compared to normal and let it glide down to the new pH you target. You don't want sudden, drastic shifts in pH, anyway...
Further dialing in ratio and concentration of nutes will probably have a more beneficial impact than the pH. pH is important too, but shifting it a bit wont result in an easily discernable improvement to growth with just your eyes. More light, better ratio/concetration would be teh biggest pieces of the pie - light being 5x more important and nute-related stuff is more about not stepping on our own feet.
the spots you see might be from the pH and it might be from ratio/concentration resulting from soil+fertilizer... it'd be folly to assume one and ignore the other possibility.
2/28 Day 56 pH is still very high, 7.9 in #2!
Emptied bases and pH'd to 6.2. Will water tomorrow once drier.
Added .75 tbsp to 1 gal pH 6.2 water for later
Trying to raise VPD from ~1 to 1.2-4..
Defoliated yellowing leaves
3/1 Day 57 Messing around with heater to try to raise VPD.
Soil still moist, letting dry till tomorrow AM
3/2 Day 58 Top water with PH 6.2 water from dispenser in am
Soil was still moist, still watered though, need to lower pH
3/3 Day 59 Check pH of water! It had raised to 6.7. Lowered to 6.3
Top dressed with gypsum, & Epsom salt. Watered again till saturated
3/4 Day 60 Third feeding
3/5 Day 61 Watered top in PM
3/6 Day 62 Removed brittle and mottled leaves
3/7 Day 63 pH'd water is rising, 6.3 to 6.7 in 24hrs. Not going to use citric acid anymore
Lowered pH again to 6.2 and watered immediately.
White vinegar seems to keep pH better?
3/8 Day 64 Defoliated mottled leaves, still not looking great
3/9 Day 65 Water with pH 6.3 + Cal Mag (lowered liquid pH to 5.5)
Lots of weird temp/rh shifts. Moved humidifier outside of tent and set it up at max near intake
3/10 Day 66 Seeing good trichome development on main buds.
3/11 Day 67 Set up self watering stands with pH 6.3
3/13 Day 41 Water dish was low, refilled with ~.8 gal pH 6.4
Defoliated a little
@@StinkyBudz, Thanks! Yeah these were freebies too. I still have a lot to learn and experience, I'm afraid the soil I made is way too heavy on perlite but so far they seem to be doing ok.
Hongo
