Yellowing of undergrowth within 2nd week of veg
CoastalEisenbergstarted grow question 4y 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

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!

turned yellow, what's the problem?The big burdock at the root started to turn yellow a couple of days ago, the tip is drying and bending. This is a deficiency of phosphorus and potassium on the 45th day from the nut (7th week) - or am I wrong? How to fix it?

Yellow leaves since 1 weekHello my friends,
More and more yellow leaves since 1 week.
I need to be worry?
I think it's not a problem of ph because my other plant look healthy.
Maybe too much water?
I just give her 2 x 0.6 liter per week and fertilizer only 1 times per week.… Show moreWeek 11

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?

Possible deficiency/humidity/pH problemI've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater
