I would welcome some advice please.

Indica
White widow auto
Week 2 of flowering
Soil ( not loaded)
Tap water declorinated
Ph 6.2
RH 42/49
Temp 77/81
Lights: Spider Farmers 4000, 20" above plant, dimmed to 80%
14/10 circle. ( I am flipping some Photoperiods in the same room)
I grow in the basement. No tent

Nutes
GO. Bio Grow 10 ml x gal
GO Bio bloom 2.5 ml x gal
GO Cal Mag 5 ml x gal
2 fans
6"extractor fan
6" air intake

Total 7 plants 5x5 area
All plants started having some discoloration when I got the new light two weeks ago.
It looks like nitrogen deficiency, but also light burn or bleaching.
I flushed
I tried foliar feeding some GO Bio thrive.
What do you all think?

I think with the new light you need to up your feed.

Yesterday I gave 1 gal water with nutes. Do you reccomend I let it dry first, or feed again tomorrow?

 

[Gabby987]

I upped the feed, but she was still miserable.
Today I gave up and flushed properly with Ph tap water.
Runoff Ph is at 6.4.
5 gal container. I used 15 gal water. I did not have enough stored, so I used straight from the tap. My water is not highly chlorinated so I hope it's all right.

Flushing them to death lol .u should check ppm of runoff to give you an idea of where your at.. and i can tell they are underfed . Let them dry out then feed a stronger solution ... Better than overfed takes a week or so to see results .When the pot is light then feed.Youll be ok .. i keep my plants limey green too much N is not good for growing big buds..

Thank you so much for your input. I only flushed this one. Poor thing, it's going to take a while to dry out. I put a gentle fan on it to help. They all looked underfed to me as well .
I do not know ppm, but my meter is coming Wednesday. I didn't realize how important that was to have.
