"Hermie" is a term that gets way too overused. I've reproduced feminized plants down to S4 breeding levels...and they basically all look the same when they are side by side..and even when trying to genderbend one of them by spraying them with colloidal silver solution (I make my own of course...
anaerobic composted soil in buckets....
tap water 6.8 to 7.2 and CalMag..
CFLs 6500 with aquarium UV bulbs...small fan blowing on them from day one until they finish.
..I don't grow in coir or hydro..I don't over do it with lights...12000 to 19000 lux at leaves is fine.
My tap water is 6.8 and the soil fixes it down a point or so..just have to settle out the chlorine for a day..I notice when I add Cal mag to the water (light dose at 5ml/gal)..it readjust the water..my leaves telle that the plants are fine with it..but I don't grow in coir..except for seedlings..
Pistols still coming in white and fresh..if trichomes are still showing clear and some milky ...I would let her go 2 more weeks...watch the Chrome's closely on her buds..not sugar leaves..when you see 20% amber it will be time...may as well let her fatten up the buds some more..yellowing leaves...
Pulling back on nutes..does not do anything really..the plant will uptake what it wants..weather in soil water coir..same with people who think that flushing a plant magically makes it have less muted in flowers..no way to do that..plants don't work that way..feed her till she's done!..nice pics...
Your plants look great ..but you need to get a bit more resolution and magnification for us to know..here's what I mean..Mine are still showing clear trichomes so probably two more weeks..the short one is likely an indica..so flowering should be around 8 week mark..depends what kind of high...
Root rot possibly let it dry out..people sometimes think dry leaves means too little water..when it can also be to few healthy roots from date of over watering.
You want to swing temps by less than 5 degrees between night and day if possible..otherwise humidity and condensate can be an issue...also less stressful for plants!
Leaf mould of some sort..if no bites out of leaves..Humidity is too high in room/ tent..knock it down to 20-25% and leave it there. Weed doesn't need high humidity unless cloning...also stop spraying your plants period ..that looks like house mould from concrete..if the tent changes temps back...
Depends on cannabis variety..my indicas like it at 20-22 C daytime and 17-19 C night time..I keep it that way from seedling to veg to flower to harvest. Fans on from day one of course !
Week 2 of veg it looks like..maybe 3rd..you shouldn't put small plants into big pots..the roots don't form properly because the water drains away from the plant..might stunt the growth..it's better to size up the pots according to 'drip line' of leaves (outer measurement) where they hang over...
