More issues... Also started wk1 of flowering too. Freakout! Help please! x.x

Hello everyone.

So I started Flowering this week, and about to start week two.
I changed 4bulbs the 1st day and added a few hours to night time. 2hrs
Then next day I added 4more.(per lamp, forgot that part) also more sleepy time too
waited a few days and then added 2 more. Per lamp.
Leaving 2 blues in the lamps(maybe you can tell in a pic adding in a min.)

I followed a feed chart and added a little bit more feed.
My PH has been going coo coo nuts the past few days.
I heard this is semi normal. But water temp is about 67/68f`
PH 1st dropped and then when I fixed that next day it jumped.
Doing my best to keep it at 5.8
But it has been a fix all day thing.
I check it every few hours (if I have the day off)
But PH has been bouncing 5.7 to 6.1.
I get the PH to a bouncy 5.7/5.8 Buy a little more time. Type of thing.

PPMs are 1300. It is a few over a basic "moderate" feed chart from Homboltz's (how ever you spell it)

I have a lot of pics. x.x

faster over view;
Lights are 8bulbs (per lamp) T5HOs
each has 6 red and 2 blue bulbs.
PH is 5.8ish
PPM is 1300
water temp 68ish

1st are the seedling. Still hard to fully tell what it is yet. (think its a girl but not sure just yet) Before the change to flower. They was the best green and fastest at growing. Now there is the lighter green and not as full.


2nd seedling


this one is 707 and best grower out of my clones. She has little things going like bottom leaves and the lighter green again too,



the two smaller clones. Hopefully you can see the stuff going wrong in it. (and see the lights)


Next is the big girl. She still has issues as well but not like the last one.


This is the smaller clone and the girl that has had the hardest time staying healthy. (there is a few)


Eck!!!!!!!!!!!

Is this all from feed or light change? Prob feed yes? Too much or not enough x.x

Thank you as always!

The yellowing of the old leaves is N def. The yellowing of the new growth is either 1. heat stress , poor airflow -temps too high or 2.root system issue probably due to root browning,are you using h202 in the res?.

Hydrogen Peroxide? No I have not. I added hydrozyme. My roots are only blownish when I let feed get all gummed up on them. There is a 4' air line in the 4"PVC pipes. That I use to well do it's thing and keep water from sitting and give roots more air.(Air flow is low coming from it) I will bounce the air line from side to side. slowly at 1st then a little more. When the water is flowing. Other than the gumming or collecting. Most of the roots are a nice bright white. Of course unless I didn't semi rinse the roots.

Air temp in the room bounces from 70ish at night to lower/mid 80f`
They always have had this temp in the room.
Humidity is around 20-50ish% If fans are on and the door open and so on.

I added more CalMag a min ago too. Or Is CalMag not really the right thing. This time x.x

those little spots of necrotic leaf tissue would indicate to me that the system needs flushing and pay attn to ph....jus sayin

I do pay attention to PH. I check it 6 to 12 times in 24 hrs. "PH has been bouncing 5.7 to 6.1"
It shouldn't do that in that range. At lest I would think. Though it is my 1st flowering of pot soo. Whatever. I know and most know I am not a genius at it yet If you look at the pic of the two. It is the one on the left. So it can damn up the feed that is a little more heavy side. But I jingle the air line for that at lest as many times if not more then I check my PH.

I'll do a early water change and flush.

Well I took her out of the pipes and dipped her into 5gl dis water. there was a nice ring of muck around the Hydrton (how ever you spell it, tad high on me meds) Cleaned it up ran the pump for a little longer so any heavies would slide on out. (Normally always a tad in there. But that is diff) And added about a cup of CalMag. When I added more. Letting the water run for a few before checking the ppm's

But should I still add H2O2 with using Hydrozyme?
