Hi, My fan leaves are starting to yellow and die. Just effecting fan leaves - the new and young growth looks good. Can someone please help me? Here is my info and pictures - also - how does the bud formation look so far for day 24? 1. Flood and drain 4x4 table 5" pots with hydrocorn and rockwool chooped cubes in a 4x4 tent. Tent is open when light is on with 2 oscillating fans so there is good circulation 2. Temp - 78-84 3. 20 gallon reservoir - goes through about a gallon of water a day and PPM goes up so I have to add more water. PPM range 640-760 Strains: Herojuana and Sour D - both strains effected equally Nutes all from Botanicare at about 75% less then recommended on the feeding charts Botanicare Cal Mag Plus - 50mg/20gal Botanicare CNS17 Bloom - 250mg/20gal Botanicare Hydroplex - 30mg/20gal H202 - 50mg/20gal PH - 6 PPM - 645 Any help would be GREATLY appreciated!!!! Thanks in advance Patrick
Yeah I was thinking Mag deficiency too so I added Cal/Mag 50mg 4 days ago and no improvement here are the nutes I added when I mixed a new batch 4 days ago. Nutes all from Botanicare at about 75% less then recommended on the feeding charts Botanicare Cal Mag Plus - 50mg/20gal Botanicare CNS17 Bloom - 250mg/20gal Botanicare Hydroplex - 30mg/20gal H202 - 50mg/20gal PH - 6 PPM - 645
MgSo4 is a great bud finisher/ripener. You should use it for the extra Mg and the extra sulfur. Yes, you most def need a micro.
Your only getting 1.2% of Mg from the Cal-mag and you get 9.8% from espom salt plus the sulfur. Epsom salt use at .5-1 tsp a gallon.
No. The garden supply has a kinda made for plants. http://www.amazon.com/Monterey-LG7220-4-Pound-Epsom-Salts/dp/B002CFRAYA/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1369955994&sr=1-1&keywords=epsom+salt+garden If you foliar feed, do 1/2 tsp per liter. But I wouldn't spray anything on a flower, that is a veg technique. Systemic will work great for now!
Go easy with the epsom salts tho, it's pure sodium and can skyrocket your PPM. It's a good source of magneseum though, and effective PH down. Just don't use too much or you're going to burn your plants up.
It definably looks as if your using to much nuts... I happen to have my bachelors degree in plant sciences.
That's what I though too glassgodd, especially since my PPM goes up everyday and I keep needing to add more water - bu the PPM after mixing the nutes is only 645 PPM won't that be fine for day 24 flowering vegged for 4 weeks? Should I add more water and lower the PPM to 500 and then check it every day and see what happens? With the epsome salts - do I add .5 tsp per gallon to my reservoir?
For nutrient availability, the ph being 6.0, you're right into a P and K lockout. Not giving any Micro you are not getting enough chelated zinc, mn, ++. I def don't have a bachelors in plant science though....
It's not to far into flowering to flush it really good readjust the Ph to some good distilled water and slowly add some nutes back. but give it a day or so before you add any nutrient solutions back into your system. also what type of light source are you using if i may ask? its really cramped on that table are you getting enough fresh air in your tent? a lot of times people will get cocky and look too much into detail instead of giving the plant what it really needs some good natural t.l.c. dont worry but act quickly because that kind of stress at this point can affect potency and yield noticeably.
