I had some rust coloured spots on some of LBs leaves. My local hydro shop and maker of my nutes suggested was not due to deficiencies rather it was due to a lack! For a few feeds I upped 1 ml per litre per nute. Guess what? No more problems!
If you’re in Ottawa check out BnB Hydroponic, they’re life savers!
Overwatering is everyone's fear but your coco looks very very very dry so keep your eye on that... also drop the humidity 80% is to high and will stun your growth along with knackering your carbon filter if your using one
@NomadGrowDad, from what i have been reading over last few days as i just started a new gro 70% when seedling pop and decrease by 5% a week until your dow. To 50 and then 40 near end of flowering everyone finds there own way though
@NomadGrowDad,ive always gone around 60% for veg and then 50% ish in flower and late flower 40% max.... thats how ive always achieved the best results.....
Thanks @autoseedsman,
I was warned to not water whole 5 gallon pot when seedlings as roots are not developed. So I’ve been focusing 1/4 litre around their base every couple of days. Thanks for the tip about the RH, you recommend 60%?
Very nice grow! Just a week or so ahead of you with six White Widows and leaves looking pretty similar indeed! Enjoy this next phase and happy growing!
