I am asking in this post about the 3 feminized Indica-dominant seedlings and their issue(s).
Apologies for all the details, im still working on getting a grow log up.
SYMPTOMS:
Orange and pale yellowish spots, and cupping.
My setup:
2x4x8 tent
FFOF cut with perlite, about 6 to 1, soil to perl
300w LED Mars Hydro SP3000. 21-31 inches above canopy, at about 60% power; 24/0 in veg.
6” AC inf. duct fan (exhaust) w/ carbon filter
8” passive intake, filtered
6-inch oscillating fan [above canopy while they’re small; will add fan below later]
4 total plants (for now):
3x fem’d indica dom. from Twenty20: Avenue of the Giants [labeled “A”, “B”, and “E”]
1 mystery bagseed (Sativa dom hybrid?) [labeled “D”]
pics follow Below...
if interested, here are details:
(The bagseed seedling is doing very badly and may be pulled anyway. Ignore it.)
Watering was inconsistent the first week or so; OVERWATERING may be an issue early.
They got from 15 to 30 ml of water each of the first 5 days (from sprout); then up to 60 to 90 ml, until out of solo cups, every other day;
then gradually up from 120 ml (1/2 cup) to 500 ml in 1-gal fabric pot, at around 2 weeks; and now just every 3rd day.
Watering with tap water that has evaporated for 2+ days. Starts out with a pH of 7 to 7.1, and TDS around 100.
I pH‘d it down to 6.4 for the first 8 or 9 days until advised i didn’t need to with FFOF. So no pHing this past week. Also, I used vinegar to ph down for 4 or 5 waterings before being advised not to make a habit of it.
Light distance and intensity also varied in first 2 weeks. Suspect possible LIGHT BURN;
Maybe more likely, High temps could have caused HEAT STRESS: Temperature and Relative Humidity slid out of optimal VPD range: Temps hit 87 in the tent one day for a few hours (while RH ), and subsequently showed more extreme yellow/orange spotting and cupping.
Maybe 24 hours of this light is too much for them?
Up-potted early: From solo cups with seed mix, to one-gallon fabric pots with FFOF, at just 6 days old. Suspect NUTE BURN could be affecting the fem’d indicas particularly. It could possibly account for all these issues. It could be what stunted the bagseed’s growth too, I guess.
Possible deficiencies suspected in the bagseed (or maybe a lockout?), which my totally untrained eye believes to be a sativa-dominant hybrid (the seed was 3 times the size of the little indica seeds, the sprout shot out of the ground fast and tall--before practically shutting down completely], and its responses to conditions and watering seem to be opposite those of its fem’d indy sisters).
And my biggest worry now is that they may have a fungus like rust or something sketchy like that.
I am a first-timer, so i’m sure i’m making lots of mistakes. I think over-watering and up-potting early and into hot soil may be my most obvious mistakes. At 13 days old I forgot to refill the humidifier and RH dipped below 40% briefly. At 16 days old I messed up the heater cycle and it hit 87 degrees (F) for probably a few hours. Folks suggested LEDs can require slightly higher temps--into the low to mid 80s many say--but I think this light--at least at this stage of growth, and with this strain, prefers high 70s maybe to 80-81?
I’ve been reading a lot, maybe too much, and I made the mistake of not choosing a strict course from the start and sticking to it. I let too many contradictory theories/styles confuse me.
I have been trying to resist feeding to treat these early problems, but I did break down and add CalMag a couple waterings in the second week, and after 2 weeks, top dressed with some Kelp meal. The suspected sativa bagseed seedling also got half a tablespoon of Crab meal mixed into its topdress--I didn’t want to add any Nitrogen to the 3 girls since I suspected nute burn from the early transplant into “hot” FF Ocean Forest soil. They all had some Earthworm castings and myco mixed into the soil too.
I am not experienced enough (at all) to diagnose issues I see. 2 of the 4 plants showed some stretching which leads me to think they want the light intensity turned up or the distance shortened; but 2 other plants show signs that I could interpret as Heat/light stress. Of course both could be true, or neither.
I suspect Heat/Light stress AND nute burn from the early FFOF transplant.
I would appreciate any kind suggestions, advice, questions or encouragement.
thanks everyone, stay healthy and free.
