This is usually when I start chasing down " deficiencies " and want to increase ppms, maybe not the way to go...
The first shot shows the LA Confidential in week six, a bit of burn but a lot of canoeing, mainly in the upper half but some down low too. The lower left corner of the at pic also shows a BC Diesel that is ten days behind the LAC , on the same system, and it is just barely stating to show signs of the same issue. Ten days ago the LAC looked similar.
I have 2- Ideal air humidifiers in the flower rooms but no true fogger. Since I went to dosers I have been doing less water changes, like once every 2-3 weeks. Last run I started dosing epsom salts rather than using extra cal mag because I didnt want to get too much calcium in the mix but this run I am using full dose Cal mag, things look much better. One thing I did do is bring in Clean grows liquis booster a little earlier than calls for but just a few days early.what both of you guys are showing pix of points to possible Mg deficiency. i believe the 4-4-9 (without floragro) is a little light on the Mg, and higher in P, which might not be best for water culture.
epsom salts could help. or for $$, Fulmag. but it's not necessarily as simple as "more Mg". too much P can cause Mg & other deficiencies. can't find literature to back it up but P is more readily available in straight up water vs. other mediums. if i'm wrong i hope someone corrects me.
what kind of dosages are you using with the dry kool bloom? i'm only using it very sparingly late in the cycle. max .2g/gal and i'll do that halfway thru a batch so it's only in there a few days. regardless, JMcG your buds look awesome. frost all the way down the fans like that always seems to curl the leaves.
JMcG, what are the symptoms that have you lowering the nitrogen? just curious.
Tbone, how often do you change out nutes? do you have a fogger?
Love the dosing set up btw!
Maybe someday... kinda high tech for this mountain man.
Damn tbone... friggin excellent set up.
Yeah I think we are chasing the same problems. Seems like I always see mg deficiency by the end of the cycle, maybe not a bad case but it is there. On this run I think I threw a PK booster ( liquid kook bloom and maybe a touch of dry) too early. Read about it somewhere and thought I would try it early, like ten days from flip. It did kick them into budding high gear with lots of early pistil formation, but may have led to my problems later on.
That Lucas formula that I was using for eons with success was not really doing it for me in the UC , I think the cali magic and micro combo was giving me too much N. Palmeezy, I kept getting really dark green leaves and some light clawing.
One thing I will change up is to start tapering nutes back starting at what... week six or so. Something I haven't really paid enough attention to in the past.
Also, I am certain my humidity and VPD is not where it should be. My cold , arid environment keeps me at low levels of both. Rarely above 60 ( at night) and more like 35-45 during lights on. No mold issues tho... ever! Powdery mildew... never!
