Anyone else think this is nutrient burn?

Happy new years growmies, i started these autoflowers 3 weeks ago and juat started the nutrients and now im seeing this. I only used half of what it asks for and ive been using these nutrients for a number of grows with no problems. Im using humbolts secrets A&B with calmag in 5gal pots using Tupur Royal kings medium. Im wondering if i ovwr fed them and if i should flush them or let the pots dry out. Any suggestions? Any help is greatly appreciated lol Happy growing

You are in Coco?
What is your pH going in and out?
In coco,you want it going in around 5.8
To me they look hungry,are you keeping coco moist?

Its my first time using royal gold tupar its like 35% coco it doesnt give me a ph range. Im used to soil so ive been ph it at 6.5 i havnt checked the runoff yet cause this was the 2nd time feeding. So tou think i should be at 5.8? Should i adjust down slowly or just bring it down to 5.8 right away?

If it is coco ,yes ,5.8
I don’t know anything about that product you are using, is it a mixture of soil and coco?
If it is soil then 6.5

My bad and yes ive been watering every couple to 3 days. Im afraid im going to over water.

As a coco fiber based soilless medium, it requires high levels of calcium and magnesium to unlock its true potential. With an astounding balance of oxygen and water holding capacities, Tupur can be watered up to 1-6 times a day!

Treat it like coco cause it is….based on web site. I’ve never used it
Lower ph etc unlike soil

In Coco perlite mixes, you don’t want to let it dry out. :+1:

Yeah i saw that online but it didnt say anything about ph and ive never used coco so its all new to me lol ill drop it down to 5.8 and give her a little more cal/mag. I juat dont want to burn it. So it looks like the way it does because it cant absorb the nutes?

So i was able to check my ppms but i threw out the water before i could check the PH runoff lol im still learning. I have 3 plants plant one came in at 1602 ppm
Plant two came in at 1172 ppm
Plant three came it at 867 ppm
Doesnt make sense that there all different. I just watered last night with ph water at 5.8 and they already look slightly better. Not sure if i should flush or just keep watering plain water till the ppm goes down. I spoke to the rep at royal gold and he told me i wanted to be in 500-600 range for veg . But the plants can take it higher so it all depends. I know i already shocked these but itll be a learning leason for sure. So my question is to lower the ppm i just keep giving water with no nutes correct?

Correct. As the plant eats that number will decrease. This is why you record your runoff numbers. If your runoff from the time before was 400 ppms and your target ~1000 ppms is what you’re trying to maintain, you know that next time you need to feed ~600.

There are occasions and recommendations for flushing, but i don’t see this as one of those times.
