That sounds good but you still may be low in the nutes somewhere. I'm not familiar with fox farm nutes so can't help you with that but with RO water you definitely need CalMag. During the later part of flowering I'll get close to 10ml/gal w/it for my hydro setup.
click on the link in my sig to my old grow log and in the first post I believe I listed the ppms of each thing I used.....I always use Calmag at 50 percent of the total ppms in my rez.
Yup as Weedhound said you ABSOLUTELY need calmag. Ca def can open your plant up to fungal infections!
I PROMISE that is not a fert burn. Seriously.
Hey Everyone,
The plants are looking much better... except the parts that were affected by whatever the problem was. New growth is fine :) and i just trimmed off all the shitty leaves. Here are some pics of everything.
More pics...
Wow, you have more plants than I thought. Hope that solves your problems.
Good luck. :)
Hey all,
I was wondering if someone could help me out by identifying the various problems I have here in the pictures. I'm still a little new with hydroponics but i'm going to guess that pic 1 is a light burn due to me foliar feeding with the light on, pic 2 I think is wind damage or something, pic 3 might be a sulfur deficiency, pic 4 ?, pic 5... Ca deficiency? Thank you :)
that's starting to look like insect damaage on some of those.....are you using anything for pests?
Look MSG...I'm sorry to do this to you but is there any chance you could restate your room conditions? I'm having trouble trying to remember your lighting etc....Could you put all the specs in one post I can sort of come back to...age.....weed....you know...
ligting, nutes, medium, plants age, room temps, rh, etc etc...it would help me out alot.
Not a problem at all Weedhound,
Right now for my first time I'm growing 14 unknown plants that are 33 days old (I got some seeds from a friend) in a 61"LX64"WX96"H closet. There is an AC duct that runs to the closet to bring in the new cold air and I have a 400w MH light (18/6) that is air cooled by a 275CFM fan that runs into the attic (going to put a carbon scrubber when I start to flower). The system I'm using is a hybrid of a couple of systems... right now I have it spray the plants for 15min every 3 hours while the light is on and I can plug up the tubes that run to the reservoir to make an ebb and flow ( I do this 2 times a day, 12 hours apart). It has a 16 gallon reservoir chilled with frozen bottles to 68-71F with a pH of 5.85, ec 1008, ppm 502. I'm currently using foxfarms 3 part nutrients (BigGrow,BigBloom,TigerBloom), calmag plus, and super thrive in R/O water. The room temp is 77 max and humidity is 42% right now. My medium is 1" rockwool cubes that I started them in, which are surrounded by hydroton in 3" net pots. Oh and i have a fan in there to move the air around. If there is anything I forgot to mention let me know. Thanks
Ok....33 day old plants....I'm complicated by your system so won't offer any comments on it....I may understand it after a day or two. :D
If I had 30 day old plants here would be the approximate amount of nutrients I would be using at that point ppmwise....I use different nutes than you but numberwise I don't things should be that different. I'm talking about plants being in veg here.
RO.....10-15ppm
CalMag....350
Pro gro 350 (veg nutes) (botanicare)
Liquid Karma....100ppm
Sweet 50-75 ppm
Should come up somewhere between 800-900 with 700ppms begin CalMag and grow nutes. (I do use Superthrive sometimes but it ends up being too much nitrogen if I use it with the pro gro)
I think you are fairly deficient on a number of things just because your ppms are so low. I'm assuming you are going by the dosing listed on the back of the package? i'm just not familiar with those so couldn't say.....
