Need help with identifying deficiency and treatment

[Pondracer]

Oh and adjust the ph last after adding nutrients also. You will notice a little more overall PH down is used but this will create a much better buffer with less PH drift daily. 0.1-0.2 increase per day is normal. In my coco in veg 5.6-5.8 and a bit higher in flower 5.8-6.0 and like 6.0-6.2.mod flower on. It doesn't need to be exact and res usually lasted me a few days and I just ph to the lowest and let it drift the 0.1 ish a day. If it goes over 6.0 in veg I would readjust it.

I just figured out the drift was that bad. My res lasts about 12-14 days. Checked mid-tank last night and it was like 6.4! Ooops.

Good numbers. Could be a slight mag deficiency but what I'm really struggling with is it looks like they have to much light or heat... but it doesn't add up with your tenls or lights. I've never seen plants grown under 9000k color spectrum so maybe that has something to do with it.

I don't think they are being watered frequently enough.

Could well be brother.

Yeah its something a lot of ppl miss if it's an autofeed res. In hydro we are always looking but easily missed in a feed res as it's usually only done when mixing.

I usually wait to see roots popping out of pots, then I water everyday. When should I water everyday?

 

[Pondracer]

Are you in coco? I do it every day starting 7 days after germination and then twice a day when they go into the 2 gallon pots. Then when 1 minute on the pump stops causing runoff I go to 3 times a day for veg. Where you are now is probably where I am at twice a day.

In flower I do it one 1:10 (which is enough for runoff) 45 minutes after lights on and then 2 hours before lights out. mid point in both cycles is a :15 second burst to keep things moist. Even by hand I would do it twice a day. But thats in coco with a fabric pot. When I did it by hand I used a 2 liter soda bottle, 1 per plant in a 2g container and twice a day.

If coco I agree with @Pondracer many ways you can the watering the key is loke @Pondracer said don't let it dry out and get good runoff. If you hand water you may have to increase the runoff each time to prevent a nutrient buildup.

This is how I do it but I do have autofeed. If hand watering going to a slightly larger pot like 2-3g helps reduce how many times you need to water per day once they get going.

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...
