themonk92started grow question 5 years ago

Any help with this deficiency? 250w hps in a 5L pot, soil and perlite cx nutrients. I did some research and my closest guess is N or boron Def.

If it happens on the lower/older leaves at the bottom of the plant and crawling upwards then its a nitrogen deficiency yes, but looking at it it has discoloration between the veins which makes me think it might be a calmag imbalance. Looking very good though ^_^

Looks like nitrogen to me. Boron usually has really twisted new growth on top of the color. Iron can sometimes look like it if your PH is off.

It's been a week since I switched to flowering and new growth on the plant all has a yellow/lime green colour but this seems to go away when the leaves fully grow out and growth in general has not slowed down. Based on the pictures in my diary should I be concerned?

Guys what’s the opinion on flawless finish for flushing. I have read on many forum sites that it does not do anything does anyone have any experience with such a solution. I have used it for the first week to flush the plants and I will use it for two days of the second week.

Lower two sets of fan leaves have gone yellow, leaves on internodes in between haven't changed colour. Not sure what's causing this. Nutes? (3-4 more weeks of time released nutes in soil) Too much water? Did water a bit extra because I wasn't going to be home for a couple of days

I have tried to figure out what this could be without much luck... it seems that my leaves are having a slightly yellow tint to them under the grow light. Under normal light it seems ok, what could this be? Overwatering I am guessing but not sure.. Any help would be appreciated

Anyone out there able to identify N deficiency on newer leaves or if the lighter color is just the way the strains new growth looks? I worry and have the habit of wanting to do more more more which I am trying to stop. Trying organic. Should I roll on, feed N, or top dress?

After noticing calmag deficiency in some other ladies I preventativly hit everyone with cal mag. Few days later see yellowing on leaves (pic above). Could they need more cal mag? Also looks like could be nitrogen deficiency? Thanks for any help with this issue.

So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!

I have uploaded a few more pictures - getting worries as the yellowing is continuing. Any ideas? pH was 5.6 on Saturday when I first mixed the nutes), and then with the air stone has come up to 6.5 or so. I've added a small amount of pH down to temper this back down.

The lower leaves of some plants are yellow, then die. I'm very light with nutrients, there is no bugs into the grow room, what can it be ? pH between 6 and 7, lower it with few drops of lemon juice but bought a 3aciddown bottle. And are the buds supposed to be that big already ?

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?
