GlazedGrow Definitely over fed my smaller plant Danny DeVito before I left for vacation last week. My searching has shown the leaf curl is probably salt build up and classic tip burn. This strain or these particular clones I got are super sensitive to feeding since it was 1/ml of Grow, Bloom, Micro across 5L of water.
Only showing in a few mature fan leaves so I gave a nice big flush of straight h2o and it's not spreading across the plant.
Regarding the flowering flip: HEAT WAVE. Last 2 weeks have been a humid hell. Still haven't been able to get the duct fan to set up a proper vent for blackout in my tent and the room my tent is in sits around 28C. Fan wouldn't do much anyways so I'm going to have to wait until the heat breaks.
Will update later in week.
Nice plants mate will take off in flower. My Mint OGs have been feeding very aggressively had no issues so far at all full steam ahead. 5 week veg then i flipped them have a peep. Feed every 5 days in 23lt pots.
Cheers Harry
Or a pH issue.
Can't see any record of you recording pH levels. Very important!
Humidity sucks brother good luck with heat wave
