This is all just my opinion, everyone has their own way the grow. Your plants will grow different than the next guys so this is just some info you can look into to give you a starting point. Its what works for me.
Try not to over water and I would only try to water the radius of your leaves to keep the roots starting down until you get the 5th set of leaves. Then gradually start watering out away from the plant.
Happy frog is 6.5 ph with very little food. Oceans organic also probably won't have enough for a full grow. Definitely get cal mag food, bloom food. Check out the other diaries and see what others are running.
I stayed with
Fox Farm nutrients for this grow but only ran 400 ppm in veg and 1200 in flower. I had soil mix FFHF FFOO and Mother earth coco perlite mix, nature's living supper soil concentrate. Had to set it up that way because of my travel.
You'll need more nutrients if your using FFHF. Start out slow with nutrients.
Fox farm has their grow big, big bloom and tiger bloom with a feeding chart. I would only feed half or less of what they recommend. You can get away with using them 3 but I would definitely add black molasses unsulfered 1 Tbsp per gallon once a week in flower. Cal mag one a week through entire grow. In flower I stop the FF grow big and replace it with Alaska fish fertilizer up to the last 2 weeks of flower.
I already started a dairy on another site and don't have time to repost it here. Travel for my work only allows me home 3 days a week.
Get a ppm meter and ph meter. Measure run off from some extra unused soil to give you a base line.
I have had all kinds of soil ph testers. My concluding is they all suck. I just measure run off.
Soil moisture: i let mine dry out till the leaves show they need water. One method is to see if the top 2 inches is dry.
If your plants are susceptible no gnats. Put 2 inches of clean sand in the top of the pots, if the soil under the sand is dry its time to water.
Need ph up and ph down to ph your water. I keep min at 6.5 in veg and right before flower I go to 6.2 and stay there. Declorinate your water.. if your water has cloromine. You will need to run it through 2 carbon filters preferably catalytic. If your not filtering you can also use citric acid "vitamins c" to neutralize it.
If your measuring lux for lights 15000-30000 veg 40000 to 50000 without CO2. Up to 70000 with co2. If your lights have the new Samsung 301 H diods you may not be able to go that high. You'll be able to tell by your plants looking like the have heat stress even though the have water and the temp is not high.
I'll stop rambling, been up 26 hours now time to look at the back of my eyelids.
Here's a critical purple cola, critical plant and the rest of the grow in week 10. Rest of the grow: 2 white widows, 1 amnesia, 1 gg#4, 1 Dark devil.
