week 4 progress and a brown spot or two

Hi everyone,

This Sunday will be wrapping up the 4th week. Here is a 2 week seedling pic and then as of today. I noticed a few brown spots but only on a few of the lower leaves..not sure if I got water on them while watering and the light "burnt" them or if someone with more experience can educate me on it that would be great.

I started nutes this week at 25% and worked up to 50% for today's feeding. Then ill get to 75% and finally reach 100% by end of next week. I alternate plain water and nute feedings (I was told too by locals). and follow a pretty hefty nutes feeding that I will be creating a separate thread for after this.

I will also be topping today as well as they are all between 4 and 5 nodes.

Here is my nute schedule below. I have them growing in a 50/50 of a foxfarm low nutrient soil (happy frog I believe - its a brown and white bag.) and pro-mix.

added:: I watered today .. 2 gallons of water with nutes at 50% of what is prescribed in pic

last time I watered with nutes i did 3 gallons. 2 with nutes at 25%, and the 3rd was plain water and they seemed very overwatered for the next day and a half.. so i went a bit lighter this time with next to no run off after watering

Comments and input are welcome, thank you

 

Hmmm I was thinking that myself.. there is a pic of my nutrient list. Are you able to tell if any of the supplements I have cover that, or should I urgently add some to the regimen tomorrow? Thanks for your time

 

Ok thanks, I do have the massboost and I did add it the first feed with nutes a few days ago as well as today at 50%. But it really does seem like an insignificant amount that the list calls for but apparently Aptus is "VERY" concentrated according to my local shop. Tomorrow I'll head over to a new shop I stumbled upon that really seemed to be on the ball! I can grab Cal mag there for sure if this is indeed the case. Thanks

 

Oh I should add I also HAVE all these as well in this list that are called for the flower cycle ..sensizyme is on there and I believe that us cal mag. If i need to add ..I'm lost but appreciate the guidance

add:: I JUST NOTICED the bottom of the list mentions cal mag! I think you nailed it and thats what I have to add asap

 

Temps are always around 77-81.. tent and lights are cooled and vented out
Hum is about mid 30s upwards to 50% after watering in there and then it tapers back down with time as they dry

I let the soil get very dry.. I should water every other but at times there still is abit of moisture I will wait a day or half a day to be safe.. I get them nice and thirsty before I water them. I lift them before and after.. nice and heavy when wet and light as a feather when dry.

So when I added everything on the advanced cycle to the gallon of water at 50% strength the ppm read 374ppm. I use really good water that goes through 9 stages (one i recently learned this week is reverse osmosis, hence the cal mag needed to be added back to the water)

So when at a full strength, a gallon should be around the 750s for ppm if I just double it...I am glad you like what you have used with them.. This is my first run so its my first go around with everything lol but I appreciate people like everyone who contributed to helping out. Communities like this are amazing!

But after a trip to a different local shop, thanks to them btw, they gave their opinion as cal mag deficiency of off pics without me saying anything. I picked up cal-mag by botanicare. I was told to add 5ml to a gallon for dosing.

Can someone with experience confirm the dosing?
AND
Since I did a light watering yesterday with no run off, do I whip up a quick gallon of cal mag only and add a bit to each today, or do I let them dry out completely and add this to the regimen of nutes in 4 or 5 days because the next watering tomorrow or Monday is scheduled to be just plain water and nutes again 2-3 days after that so I am looking at Thursday-ish for nutes with cal-mag if I wait.

Thanks guys
