Yellowing of undergrowth within 2nd week of veg
CoastalEisenbergstarted grow question 3 years ago
What is causing my plants to yellow in the lower growth? Using Coast of Maine soil so shouldn’t need top feed for another couple of weeks. I’ve tried a mixture of liquid calcium (organic) and epsom salt to provide cal mag organically. Any recommendations?

Def looks like mag. If you’re confident it’s getting a good amount now, are you sure pH is in range? Cal and mag i believe taper off uptake when you get below 6

Leave troubleHello grower college's!!
As you can see I have some leaves that are yellowing. The leaves I took are from the lower canopy.
This is the 3th day since I set the timer on 12/12.
Please some help and tips. I use the Biobizz line on soil.
Thank you 😘

Yellow leaves, red discoloration on couple of branches1st plant-day 37
2nd plant-day 36
In both cases, the first leaves turn yellow at the very bottom. They are to be cut after 60 days. On two plants, red discoloration appear on some branches. Both are higher than in the manufacturer's description. Is everything ok so far?

Leaf DiagnosisCould someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?

Yellow lower leavesHi! I went out for the weekend and when i came back most of my plants had yellow lower leaves. The weekend has been very very hot and im wondering if it was lack of watering or is it a lack of nitrogen? Some in one plant the leaves were dead.

Is this nitrogen deficiency or something else?Hello everyone!
One of my plants has some fan leaves and new leaves yellowing at the bottom (and some are crispy). The plant is very bushy but from what I understand this could be nitrogen deficiency but wanted to check. The other plant is smaller and doesn't have yellow leaves
