BigBadLion started grow question 4 years ago
Is it possible that maybe I underfed my plant and that's causing my actual problem? Is it something normal? Or there's something else going on with it that I should check and fix fast? In general the plant has a lighter green color and old leaves are getting yellow. Thanks!

This is what I see based on the photo's . Firstly , you're plants are suffering from a couple different things here the first real problem I see of course is the yellowing . This is being cause by a combination of 3 things , firstly your plant is suffering from nitrogen deficiency , this is the broad yellowing that's taking over your lead , it's also suffering from CalMg problems this is the yellowing that you see that has started in the middle of the vein's of the plants leaves and lastly PK deficiency more Potassium tho , I can say this because i can see the spots starting on your leaves and they are just random spots they will turn brown eventually and get bigger . This problem is a real easy fix all you need to do is adjust your nutrient solution and these ladies will regain there health and be rocking and rolling harder then before . I would advise that you do the full dosages of PK which should be 4ml/l with fully mature plants and I would bosst the grow part ever so slightly by 1ml/l as well as add 2ml of CalMg per litre of nutrient solution you mix up . This will do a variety of things for you but most importantly slow the yellow restore the not so damaged leaves back to normal and continue to grow prosperously . For the leaves that are too damaged and will not heal properly I would advise that you remove them so they dont make a perfect nesting ground for unwanted intruders such as mites , scale , miners .. the list continues its just over all beneficial to remove those leaves :) Over all your doing well just a few things to touch up and this will be epic ! I hope this information helps you to understand whats happening a bit better to your plant and the very very easy ways you can fix it. -Happy Growing!

no it's basically impossible you under fed if you're using even a tiny bit of ferts in soil, more likely is a lock out from over availability due to slight over watering over time. Stick to a stricter wet dry cycle, just some plain water for the next two waterings then do what you were doing but minus the bio grow - hope this helps bro :rocket:

Hi @BigBadLion! Yes it looks like she needs more Nitrogen and also some Cal-Mag (or epsom salt). Make sure that your pH-pen is correctly calibrated, because that could also explain the deficiencies. Happy growing :facepunch:

Hello ! Short answer for me : your EC is 0.85 so double up to 1.7 . Your should start your Flo between 1.4 and 1.6 with Bio bizz. Take a look at the feeding chart. I hope it will help you

Hi :wave::skin-tone-5:

May I ask did you ever forget to give them water? That could be a cause for yellowing? Or the could just be telling you they’ve depleted there energy? I’d Look through all the Girl Scout cookies journals on here n check there week 6 for yellowing or problems if it’s asimilar could be genetics (while your looking check other journals nutrients there’s a few people I’ve seen just feed bloom and top max only during flowering n they end up with big buds) :v::skin-tone-5:

Hey there just a couple opinions off the photos ive seen, the lower yellowing leaves if they eventually die and fall off this makes me think nitrogen...i constantly underfed my plants and regularly had a few yellowing leaves drop off, so perhaps increase up to the 1tsp or maybe 1 1/2 tsp and see if change or slowed yellowing. The light green photos made me think of sulfur or magnesium with the light green inside and darker green outside, in addition to the N increase, you could add a minimal dose of 1 Tbs per gallon of epsom salt and watch for change. I battled deficiencies my whole grow and managed to get to the end so its not impossible, but a happy plant will probably put out better and bigger buds than the plant that struggles.
Being only 2 weeks into flower i think a couple small tests would be safe, i see most schedules dont drop off N until a few weeks into flower. If none of this sounds good, then flush her and then add in what you think she needs, perhaps her roots ate are just unhappy at the moment.
Best of luck, the buds look good aside from the leaves. :v:
