Need some help. What am I doing wrong

[Nycgreenman]

I’ve started my first grow and I choose to start with my favorite sour diesel and one I’ve never tried but always wanted to fire og. The sour d is moving right along but the fire og is failing miserably. Maybe one of you experienced growers can help me figure out my issue. I’m using GH flora series, my PH is at 5.8 I also added some cal mag..I’m using distilled water. My RH stays between 47% and 52% and my temp ranges from 75 (lights off) and 80-82 (lights on) I’m using fluorescent lights at about 4-6” above the plants.I am about 2 weeks in since sprout. I’ve included some pics any help is greatly appreciated.

No fertilizer needed for the first three weeks or until the first round leaves die. Don't pH down distilled water.
Giving fertilizer to seedlings is like giving a bottle of soda to a newborn.

Agreed! I only gave it what the bottle called for...and I even gave it less..the bottle called for .5 tsp per gallon of water...my reservoir had 5 gallons which would call for 2.5 tsp I only added 1.5 tsp. Also I figured it was getting over fed so I stopped giving it water for about 3 days and didn’t seem to change anything. However my other plant Sour D is doing great. Both have been getting the same feed and in the same tent and sprouted at the same time. Here’s a pic of the sour.

Just noticed you said don’t PH down distilled water...the distilled water I got had a PH of 7...I was told when using hydro in Rockwool 5.8 is what I should be using.

Distilled water is pure water and doesn't need to be pH adjusted, same with RO water.
One drop of pH up or down in distilled water will make the pH on a pen jump whole points and it isn't accurate. I was told that RO and distilled water pH adjusted to the soil or media ph as soon as it touches it.

The only time you don't pH adjust distilled water is if you are giving the plant plain water. If you add fertilizer to the water, it needs to be pH adjusted for hydroponics. Only pH adjust the nutrient solution after all the nutrients have been mixed in the water.

The truth about PH. Some nutrients are designed to work with RO/distilled water and carry some alkalinity. I dont know if flora series does or not but with RO cal mag should be added. You want a ph drift of 0.1-0.2ish over 24 hrs. If it's more you will benefit from a buffer. If you read this it should explain why you ph after adding nutrients. The only time you ph before or during is if you are mixing nutrients that result in a ph over around 8 nutrients using cheap chelates can be lower but it's not that common to see anymore. RO has no alkalinity and is very unstable so much so you cannot even trust the ph reading you get on your pen and as was said it doesn't matter the ph of RO because it's so easily influenced by anything added to it.

OK I'm going to do my best to explain PH since its something that is for the most part greatly misunderstood and can be confusing to new growers and even experienced growers alike. This will explain why we need both ppm and PH meters to give us informed information about PH This will be a...

Hey guys hope everyone is doing well and having a great grow..here’s a little follow up.I went away for vacation for a week and boy was I nervous. I made a new batch of nutes for my reservoir and made sure my humidifier had a full tank of fresh water. And I came back to some dead leaves on my sour d as well as some nice growth. Also noticed some slight yellowing and browsing on the tips and the tips are curled down...I raised my lights as clearly she grew and got to close to the light...I’m hoping it’s that...I checked my pH it was at 6.2...not too high but I usually keep it at 5.8..not sure if that change in ph caused the tips to yellow and curl down. Here’s some pics before and after me being away for a week.

And now after

I used a tooth pick to hold it up for some reason it’s growing sideways

After I cut the yellow and dead leaves off

Let me know your thoughts.

Nutrients just a touch high bit not worth messing with imo... they look great

Thank you My ppm shot up from 800 to 1000 while I was away..I brought it back down to 800 white some ph adjusted ro water.
