Mintystarted grow question 5 years ago
Looking for clarification on the Flush time required for a RDWC grow? I have read this can be as little as 2 days of just plain water but should this also include CalMag if I am RO water? I assume the standard root rot treatment continues? i.e. OxyPlus, HydroGuard, Phytoff?Thanks

Contrary to what happens with soil or coco, where the media keeps some nutrient and needs some time for the plant to consume it. in DWC, once you change the water, there is no more nutes in the growing media, so there is no need for a long flush, 2 or 3 days is enough. There is no need for calmag on those days.

There is no need to flush at all honestly, but if you feel you must, 2 days is fine for hydro. Just pH'd water, nothing else needed, it's just 2 days.

Yellow leavesmy little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST)
it could be due to the flushing done (but less than 5 days ago) 🤔5 years ago

Deficiency helpWhat deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think.
Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.5 years ago

Autoflower not flowering after 3 monthsI'm growing a dwarf auto-flowering strain in a greenhouse outdoors. Its now been 12 weeks since it sprouted and no sign of flowers. Someone else mentioned that autoflowers sometime switch to photoperiod outdoors. Is this a possible explanation or am I just being impatient?5 years ago

Yellow edge with brown spots on fan leavesI am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?5 years ago
