Yellow veins
AcidFarmerstarted grow question 5y ago
Hello growers, my girls have these yellow veins on the leaves, could it be a slightly too low pH and the consequent deficiency of magnesium? How can I act? Can some Epsom salt help? Thanks

epsom salt with the right ph would help, if you're using synthetic nutes give her cal mag with right ph flush

Looks like a iron deficiency to me, I had a similar issue on my Week 3 of Veg in my diary if you'd like to compare pics. Had it on the Sunset Sherbet and the Tangie. I fixed this with a foliar feed of chelated iron while I got my PH in check. The foliar feed showed results in about a day, but not a permanent fix until you fix the PH. Once the PH issue was resolved, the need for a iron foliar feed was no longer needed.

Is this nute burn / deficiency? Or light burn? Or both?What's going on with the intervenial chlorosis? Is it nute burn (zinc + manganese + iron potentially)? Is my proposed solution of only going with pH-balanced water a good mitigation strategy? Should I just not add super soil out of the gate?

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Yellow stains on bottom leaves (indoor grow)On day 25 yellow stains have appeared on the bottom leaves of two plants (critical 2.0). We don't know from what these stains are coming.
On one of these plants, some leaves have also started to develop white dots. Spiders maybe ?
Thank you.

Ok, so I’m starting to see a deficiency. Yellowing between the veins at uppermost leaves. My ph is on par. I’m maintaining my grow per normal with one change. I added Carbo load at 2ml/g.
Could that be the problem?
I think I’m going to flush today and dump my tank. Restart.Week 14

Magnesium - Nutrient problemDo I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly.
The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1.
Has anyone the same problem?
Thanks!

Roots getting brownMy Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

Upper leaves are yellow and not smoothI noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?

Is this a Magnesium Deficiency?Hi all,
Day 98. Northern Lights.
1 of my 3 NL girls looks to have a bit of a Mg deficiency. I'm close to harvest so not too worried however it would be nice to have a confirmation for future grows/learning as I'm very much a noob still.
Can anyone confirm/correct me please
