dat defol hurts :D

2 things: - i think the foliar feed is causing the yellowing - you defol too much imo :D

TL :: DR -gpw is not accurate -gpw does not allow direct comparison of growths - g per kWatt hour is more accurate and allows direct comparisons of growth - g per kWatt hour is a correct estimation of the amount of electricity (hence cost in bills) going in each growth Fellow growers, you...

i also disagree with that. a stressed plant grows less, period. so if you overfeed throughout the whole growth cycle you will have less yield most likely

This! and the problem of the lucas formula is exactly this. to get enough N for low feeders you have to have insane ppms from the rest of the nutrients. i must say i was one of those DWC heavy feeders, but i also discovered my EC meter was set with the correction 0.5 scale, instead of 0.7. so...

ye that was the same for me as well. 70 seems to be the magic number (in negative). does your room intake air from outside or just recirculating the air inside?

all is around 20C (68F). is 2 degree above optimal but still 0 signs of microbial problems and the plant is growing great.

interesting idea but a waste of electricity. you won't gain more oxygen than with good quality air pumps and stones. there is a limit of dissolved oxygen in water, and breaking down water into oxygen won't increase it. also electrolysis can generate OH- radicals wich are detrimental at high...

do these system work well for cannabis? i know one user of this forums is quite keen on them, but many other are a bit skeptical...

i clean everything with water and a bit of bleach. good as new. throwing away everything seems like a big waste of money (unless you use cheap parts like Walmart buckets and stuff).

i have a few questions: how large is your growth tent/environment? what kind of growth lights you use? what climate is were you live? i ask you these because in my case (small grow tent with 5 gal bucket, LED lights and cold continental weather) i solved my temp issues just by bying a stronger...

can i add: - check plants daily for air pumps as well, roots without oxygen cannot go more than 24h without having some stress - always have in your house new spare pumps. the few bucks/euros/pounds they cost are well worth the added value of having a replacement in case they fail (and they do...

this sounds interesting but again it contains kelp extracts and chitosan-like components. whole those are great for plant growth stimulation, being organic compounds they can trigger harmful bacterial growth if temps go out of control

yes, same here. just gave a try to the lucas for a couple of growths because i ended up without floraGro hehe in the end as @rkymtnman says is all about finding the optimal NPK ratio, and i feel that Lucas alone does not cut it, even as "entry level" formulation that supposedly is easier to...

yes but that would defeat the purpose of Lucas formula isn't it? :D one could just use the normal GH 3 parts and have the same (no nute stress and no nute deficiencies) hehe PS: also the FloraNova contain organics iirc. not a very good choice for DWC when you have temp issues like i do :D
