Hi there. 1st post of a long-time lurker.
We had a crisis with heavy metals contaminated weed polluting the market around here not too long ago, so I decided to not buy anymore and grow my own ... again, but this time indoors and with proper equipment.
So right now that's 3x Maroc/Skunk Special plants grown from seed in a DR60 vegging under 2x55 TNeon lights + one plant from the freebies. The plan is to keep 2 plants max and SCROG 'em.
They're each in 2,6 gal containers (10l), same soil mix (quality potting soil, PH-neutral, added 20-25% perlite), same nutes, same everything.
I feed them with every watering (once a week for now) with BioBizz Grow (5ml per liter) and give them some extra nutes in between by spraying them with a 2ml per liter solution of the same stuff.
PH seems to be be between 6 and 7 (kinda hard to tell on those strips), RH is between 50-80% (I humidify from time to time), temps are 25-29°C near the leaves (at night it's around 20-22°C). I have a small fan in the tent to keep a steady air flow, extraction is not installed yet, but will follow (right now I have airflow via stack effect, there's this chimney-like openening in the tent)
The soil reacts normal to watering (I let it dry out until the pots feel light, then water/feed 'til there's a little runoff).
I water with a mixture of tap water (hard) and rain water (very soft) to keep the PH balanced, but that might be redundant, dunno ... that's how I used to do it, and it worked.
They're 6 weeks now (veg), and apart from being kinda very bushy and not very high (12"), they look great so far. All but one! One has twisted leaves with yellowing margins, some superdark, clawing leaves too, and stopped growing a week or more ago (see pictures, it's about it's only about 8").
The others had those twisted leaves too, but only directly after repotting ... they straightened out, so to speak, over the last few weeks.
Granted, they all had a terrible childhood: the seeds had arrived but no equipment yet ... and impatient to start (I know, I know, bad attitude), I grew them in what turned out to be terrible coco, so all of them looked really sad & sick the first two weeks of their miserable lives. 2 pf them even died.
I repotted the the remainders in quality ph-neutral soil with 20-25% perlite ... BAM! they grew like ... well ... weed. All but one ...
So HELP! What's their damage? Reading through the forums made think it might either be a Zinc defiency, maybe Magnesium ... but I have not really a clue actually.
Any help appreciated. Thanks
PS: there don't seem to be any signs of pests, neither on the plants nor in the soil
