help with NL ?

[semajkroy]

hey guys I have two northern lights and one strawberry blue under 400 watt hps in organic soil mix with the bottom third of 6.5 g containers filled with subcools super soil in 14 days into 12/12 and starting to see a problem with the two NL they've all been very healthy and vigorous. This just showed up two days ago
I water once a week each with 1 g of tap water left out a few days
temps have stayed between 77 and 80 with the ocassional 75 -82
I do not have any ph meters I was really depending on the SS to keep everything. In balance any ideas?

I learnt the hard way that water left out for 24 hr most of the time has a PH of 7 Where water that is left over 24 hrs the PH starts dropping fast.

Northern is the strongest/hearty strain I've ever worked with out of about 20 strains. Sweetooth would come in second... It will make it!

Growing Nirvana NLights and I get the same while transitioning to flowering , followed by a little NTox ,probably from using ffof, and not vegging long enough to uptake the abundance of nitrogen in the soil creating this new growth yellowing and dark green leaves followed by couple leaves canoeing.( in my case)

Looks the same imo, this is after the leaves adjusted to the light a little.

They'll be fine.

After i found that out i bought a meter and just bubble my water till the PH drops to 6. That way i dont use PH down, if i need to raise it i just add mare tap water.

Here is a good little chart i found showing the PH and at what range nuts can be used by the plant.

thanks for all the great replies I knew they'd make it just dont want them to just be surviving ether though I'm more concerned with herms than them dying
