Yellowing in flower

Hi guys 2 weeks ago I swapped from Lucas Formula 6/9 GH micro bloom to maxibloom (7g per gal). Growing in coco DTW with automated watering system. I’m using a few additives as well Florablend, diamond nectar, calimagic. I flipped my plants to flower 9 days ago. Been away a few days for work and checked them today and they look like this. Definitely doesn’t look normal. What should I do?

I had seen online Sulfar def. ph has been good and run off ok. Lights are 17” away. And using a lux meter for a rough measurement it’s 46,000
 
Plants still are yellowing. Shitty photo I know I just took a pic with light on in a rush. Tips have some burn. Not sure bout the holes in them tho. The plants still growing like crazy so I dunno

:smile:
too much pk boost too early imo .. sort of nutrient lockout

edit : how far are your bulb from the canopy ?
 
Try just giving them a dose of micros and raise your lights a bit. They haven't begun flowering yet so your light might be a tad too close. Raise it as they stretch.
 
Micro as in GH series micro? Using a lux meter as a rough measurement the lux on the canopy was 48,000 today it’s 55,000 they seem to be stretching pretty quick.

Gh micro should work. But honestly, to me, kinda looks like light bleaching. But I doubt hitting them with a small dose of micros is gonna fuck them up.
 
I had been told on another forum to give them 2-3ml per gallon of micro. So I did this new batch of nutes.


My water is about 100-120ppm
I have a 50L reservoir. I feed them 1ml per Litre like on the bottle.

I had troubles with my light. A mate wired it wrong. Using a plug in power meter I found out it was only drawing 49.2w so I re wired it and it now has 425w They had started doing it before I fixed the light.

I changed from Lucas GH micro/bloom the 31/07/19

I flipped them the 06/08/19

This was them still on the 09/08/19. Still fine.

I’m wondering if it’s the maxibloom maybe?

Idk. If you hit them with the micros I'd just wait and let them do their thing. They look very healthy and happy otherwise. And they look greener in that pic. You're doing great.
 
I’m using the Lucas kiss method maxibloom at 7grams per gallon. I have a 50L (13gal) reservoir. My tap water is 100-120ppm. Full strength maxibloom (91grams) has an EC of 1.8-2.0 I drain about 20L out into another tank and refill reservoir with fresh water and get the ec down to around 1-5-1.6.

I’m only new to using maxibloom this is my first time. (Newbie)
Why is the formula worked out a plant gets what it needs at 7g per gallon. But it’s way to strong to use?
 
Plants today after adding some GH micro. I also found this trace elements in my shed. Would it be worth trying it?

Did you feed them micros the other day? Did you raise your light at all?
Edit: sorry I missed that you did feed them the gh micro. Whats the pH of the water you're dumping on them?

Yes last batch of nutes (last week) had micro added to it. And I took the lights up 2”

I made up a new batch of nutes today. After giving the res a clean out with h202. Filled with 55L tap water (ec 0.3) I didn’t use all the additives this time.
Armor si
GH micro
GH maxibloom 5g/gal (down from 7g/gal)
H202
Epsom salts.

All mixed ec 1.6-1.7 ph 5.8.

not sure why you use these epsom salts
.3 ms for base water is the right number, there must be enough calcium magnesium in it for your hydroponic needs
still looks like a nutrient imbalance
