deficiency help please!

I've scowered the forum but can't find what I'm seeing on one of my plants
two weeks into 12/12.

The leaves are yellowing (light green) ad the veins are really yellowing. Some leaves that are still generally green show the yellow veins.

What could be the problem. My water pH I try to keep arount 7.0 but could be as high as 7.2. The first week into 12/12 I used a diluted Peters Bloom Plus.

Help please...

if Leaves are a uniform yellow or light green; leaves die & drop; growth is slow. Leaf margins are not curled-up noticeably. >> Nitrogen(N) deficiency.

if Margins of the leaves are turned up, and the tips may be twisted. Leaves are yellowing (and may turn brown), but the veins remain somewhat green. >> Magnesium (Mg) deficiency.

if Leaves are browning or yellowing. Yellow, brown, or necrotic (dead) patches, especially around the edges of the leaf, which may be curled. Plant may be too tall. >> Potassium (K) deficiency.

if Leaves are yellow or white, but the veins are mostly green. >> Iron (Fe) deficiency.

if Leaves are light green or yellow beginning at the base, while the leaf margins remain green. Necrotic spots may be between veins. Leaves are not twisted. >> Manganese (Mn) deficiency.

Here are some close up pics of whats beginning to show on ALL three ladies. What do you think it specifically is?

bump........

look like my plants lol. Which is a dificeincy in mostly n, but everything else too. Buy some biobizz, its pretty good. good luck.

What about when leaves get red spots on them what does that mean... because the colors arent changing and I have tried just about all the N-P-K tricks but it still wont go away

great infos

the little white spots in it could be pH "hotspots". i would try to stay away from the 7.2 pH for the meantime. it could also be a pH flux. where it has change rather drasticly in a short amount of time. some ferts when the break down have pH changes, soils too.

Hey all,

I have some kind of deficiency that started about 4 weeks into flower. It appears to be MG to me but I'm no expert so here I am. Any ideas? The leaves are curling up and scorched like hell but the plant is still flowering like "normal", that is they continue to grow. Also, it's occuring near the top of the plant, not so much in the middle or bottom. I flushed at week 5 for 2 days, then added nutrients again at 900 ppm. I use a flood and drain system as well. My ph is constantly between 5.7 to 6.1. At one point, it got down to 5.4 which makes me think that caused MG deficiency. Will it be ok until the end of flower or do I need to do something now? I'm currently at week 6. I wasn't able to upload pics due to an upload error but they're in my profile if you can view them that way. Thanks!

yup that's a mg problem
