Hi dubi.
Heres another post with some concerns and doubts which your help and hints would be greatly appreciated.
My plants are growing fast!!
The colour of the upper leaves are turning yellow and 1 leaf had turned itself upside down
I lowered the light 2 days ago, and when they were checked yesterday they were looking unhappy. Searched forums here and came up with; the light was to low. 50cm or 20" from plants canopy,
so light was raised instantly, to 95cm/ 37" above canopy. This afternoon plants are looking happier although upper leaves are remaining yellow.
I do understand that if this was the problem, it's going to take a few days to correct itself?
If the light was plants only problem?
monday 2nd Oct, i gave plants some Bio-Bizz Bio-Grow. They got 0.5ml per Litre of water, and were all watered a total of 4 Litres.
Last 3 nights they were watered between 3 and 4 Litres, with 1ml per litre of Bio-Grow.
I've also found by search that plants may have a Magnesium deficiancy?
Was tempted this eve to give them some epsom salts, but i have with-held, as lower leaves are a sign of Mg def.? doubts here also?
8 plants growing fast!! and im knowing that im not going to have room, so am wondering when to sex my plants? ready for eviction of males?
And finally, when roots appear at holes in bottom of pots whether to re-pot in intermediate size pots, im thinking maybe they're in that size pots now? so into large pots? and whether to continue with Plagron light mix or to use another compost richer in nutrients which is what i'm tempted to do.

temps have been between 23 and 27 and Rh has been between 41 and 59% theres a humidifier going into room tomorrow and i'll see how that effects things?
Apolagies for such a long post, a whole lot has happened in 6 days!
Thanks.. Sustenance
