Hi there, im new to all this and have already made some mistakes, i have feminised AK48 plants, which are now almost 1.5 months old and are 2 - 2 2/1 ft tall, a result of bad/wrong lighting(incandescent/flourescent mix) resulting in the stems getting all the attention with little bushy growth. They also possibly had a few days of heat stress (under 400w MH/ bad ventilation) and are now outside( 1 week) and the daylight hrs at moment are 16/8. I repotted them into 5L pots with 80/20 soil/perlite mix and have stopped giving fert( soil mix said a 6 week supply nutrients), i also flushed them yesterday as i dont know if this is a heat stress thing or fert burn, the soil is PH 6.5-7 (however with a cheap electrode PH measuring stick), dont know the water PH so cant tell whats up. Also 1 of the top fan leaves has started go look a bit fuzzy white, lower leaves are showing signs of yellowing. does any of this sound familiar, any suggestions on what to do. I want to get some cuttings, possibly leave these girls outside to see if they get bushy. PSICS ENCLOSED. ta.
Looks like nute burn. What soil did you use? Heat could do the same though so you might be right there. I would do at least 18/6, not 16/8 too but that has nothing to do with this.
