Should have stuck to growing tomatoes and greenbeans

[BigSm0]

I will do my best.

I'm growing wonderful autos in an outdoor shed. I built a room inside the shed, plywood outside, roxul insulation, and moisture resistant drywall inside. Painted satin white. Active exhaust kicks in at 75 degrees to keep them cool. Humidity stays around 40%


Lights are 2 kind k5's 1000 watt 12 spectrum lights. About 25" from the tops

Strains are Girl Scout cookies and vast and fast


Grown in pro mix hpcc in 7 gallon air pots.


Nutrients used are biobizz. Everything but the extras algamic and I forgot the other. Instead I substituted bio weed. Feeding every 4-5 days since pots are so large in between watering a would push feelings to late. Feed amount is 30% the recommended on the light section of the manual. Also with plenty of runoff.

Ph is 6.0-6.5 filtered well water with Ppm around 300

The plants up until flower were extremely impressive. Then I started noticing the lower leaves yellowing and dying off. Then the whole plant started turning yellow. I think I added the flower nutrient part too soon as I was told that could cause part of this.
Advice was to do a nitrogen foliar spray. Which I did once.
Then advised to flush. Which I did but again messed up and didn't feed them for a few days.
I didn't have tons of time and only ran 10 gallons through the pots while runoff was still colored so I did a water a couple days after to help with the flush.

That's when things turned bad. It appears to be a magnesium and or potassium deficiency. Overall still a lot of yellow, very minor burnt tips and now the spotting and brown leaf ends.

They are close to the end, maybe day 50-55 and I really hope they recover and produce. It's my first grow and I went over budget by about 10k so some sort of reward would be great. I will do my best to answer any questions.

Thank you for taking the time to read up on my mess.

When using led lights you need to use xtra cal-mag from the beginning.Also veg nutes should bed used until well into flowering.I'm not positive but with those strong lights could be too close witch will cause the leaves to discolor.It might be to late to fix it but I would raise the lights a little add at least 2tsp per gallon cal-mag at every water and continue with flower nutes.

I did just purchase the calmag. But only did 50% the recommended on the first feed. Should I increase it to the recommended? As far as the lights go I started with mh than went to Mars hydro and now I'm on the kind led. Initially I did have them very low, 25 is the minimum distance and that's where they are at. But I will raise them more.

Another thing I'm debating but am unsure of at this point is going 100% cmh, light emitting ceramic 315 watt by sunsystem.


My new room is currently being built and the plants will be 4 per 3x3 flood table. Still in air pots but in the tables to drain the runoff. I think 4 would work nicely and the heat benefit is great.

Thank you namvet

What up nice to meet eveyone. Your plants look great honestly.. I'd give them full,dose of cal mag and up your nutes to full strength . I don't think your giving them enough juice ..just my opinion. Example ... I have 2 auto bombs and 1 nLxbb that are 23 days old and I'm feeding the 3ml per liter of advanced nutrients grow micro bloom and 2 ml per liter of b52. That almost the full recommened dose of base nutes and they are only 23 days old . I'm growing with a mars hydro pro epistar 160 . I haven't had any issues with cal mag yet but I Bout some just in case . I'm subbed up bro . Don't switch to growing beans man green is where it's at

Thank you resinous! For a first grow its going ok. To be 100% honest I didn't know a single thing about growing until 3 months ago. Thanks to so many forums, the net in general and YouTube I think it's going pretty good. It's funny I see some grows and wonder what are these guys thinking. Then I think back a few months and without time and research I woulda done the same.

Dude I know what your saying . Just remember cal mag more nutes . If it were me

I did add some more calmag last night. I think it's called sugar daddy too. Which is sulfer and magnesium.

Think those 2 should really help out a lot.

I'm also switching to flora duo 2 part nutrients for next round. Problem being a new grower is the organics take to long to really work and being unsure of the issues time is a killer. Then add in the auto flower sensitivity. While mixing in 7 different bottles like a chemist there is plenty of error along the way I'm sure of it.


I started with the biobizz pack. 5 bottles and was explained to be a complete system. After a couple feedings I ran out of bio heaven. Also the smallest bottle on the box'. Had to Amazon a larger bottle at 70$. Almost feel like the got me hooked and now I'm stuck with most bottles being 75% full and needing to re-up on the heaven at a hefty price.

Dude same thing with advanced nutrients that I use . I bought the 3 part and the hobbyist bundle , the bundle comes with voodoo juice b52 over drive and big bud . I ran out of b52 half way thru the grow . But it was only 36 $ to replace.
I really like the advanced nutrients because I font ph anything. I use ro water and just mix the nutrients and stackers together and don't have ph anything because it is ph perfect technology. . It's great and I haven't had any cal mag issues even under the led . Just fed them full strength . Believe me I don't think your going to burn them . I

I had a little tip burn a couple weeks ago but the plants were super yellow. Go figure. Oh was always perfect and even runoff was super close to what was going in. So I don't think it was a lock out. The biggest problem that I see was the lack of experience. Now the advanced nutrients sound pretty bad ass. I briefly read up on the ph perfect part and was shocked. Somehow shortly after was distracted by diy cobs lol

Nearing the end of my first grow and I really appreciate all the advice You guys shot my way. I think the plants are doing great. Have to say I had real high expectations till the first few weeks and I realized I was far from prepared for the grow.

I will have a weigh soon enough, they have a week or so left I believe. My cheap ass Amazon magnifying scope arrived broken so I need another. Once it's I I'll have a better idea.
