1) After 2 days of gentle light, all seedlings/cubes were planted into their net pots with the clay pebbles and placed under metal halide (15000 lux)
2) After 24 hours under MH, CO2 enrichment applied and intensity increased to ~55000 lux (60% RH, 29 deg C)
3) Solution swapped to week 1 vegetation as per Canna nutrient guide (roughly 600 ppm) after cotyledons showing signs of depleting magnesium (not a problem but figured they showed that they needed some nutes)
End of week 1 - all seedlings strong and vigorous. Some mild nute burn (or maybe heat stress) on tips of 1st leaf set, probably due to excess calmag during early days or very intense light, however, second leaf set are looking happy. First 3 are a little stretched as they were held back to wait for the laggards to emerge.
sounds like a true hermie,coming from genes,not stress.It'll throw out and grow balls whatever you do.You can remove balls by hand but there will still be a lot of bananas or sacs that can't be reached.Up to you mate,toss it or keep it but you'll most likely have seeds off other plants too.Quality won't diminish hugely but this one looks like a bad genetic.This is why I hate barneys.I've had stupidly non sense plants from them.Commercial breeders always do this.Mix crap seeds with healthy ones and sell.I'm avoiding barneys.Just keep in mind.
@HighRoller909, thanks mate I appreciate your quick reply. Knowing that it's genetic and not stress related makes me feel better about my gardening haha. But still, I will remove it - I'd rather 4 plants without seeds than 5 plants with seeds.
@sloppyjohn, your ph range is 5.5 to 6.0 for veg and 6.0 to 6.5 in flower. The higher ph in flower allows for better p and k absorption 6.0 to 6.5 in veg of 5.5 to 5.8 allows for better N uptake. Plants don't need much N in flower. It will pull from the leaves if it needs more N.
nice you should fully cure over at least 3 weeks. and then see the high will change it wont turn you melancholic anymore. its because your weed isnt matured enough.
