What Could This Be?

I am just starting to add lime to my soil, still see mag deficiencies here and there. Good to know though. I am sure that adding more calcium means the plants need more magnesium.
 
Hey again guys, I just thought I'd throw in an update about this plant. new growth still looking good although getting a little bit of yellowing coming through again. This time it looks almost like a yellow finger print in the middle of the leaf (pics will be up soon) also, I am noticing that some of the stems appear to be slightly purple although it is only on the top side of the stem and isn't very pronounced.

Im not stressing to bad, as growth is still good. I also started LST on it today, nothing too crazy, but got a reasonable bend. I'll put pics up after the hockey game tonight and hopefully you guys can have an opinion about possible causes.

Thanks.
 
Here are the pictures; Two are of the leaves showing what appears to me could be Iron deficiency (Although I'm far from certain). Also threw in one of the LST just so you know what I'm working with.

I noticed something I thought was strange too. As much as I read about how cannabis grows (1 leaf set 3 leaf set 5 leaf set etc etc), I never actually did get a 5 leaf set...I had a 1 leaf set, a 3 leaf set, then imediately a 7 leaf set. is that weird?

For f@ck's sake, just when it was goig good it strikes again!!! This looks the same as the first deficiency, there is somthing missing or in short supply and your not covering it. I don't know, there must be more to this. I have to re read a few pages first but this plant was getting strong and healthy for a while!

Thanks Kingrow, although without all the help I probably would have killed her by now haha. Based on your recommendation, I just transplanted into a 2 gal pot with a mix of 4 parts Schultz Potting soil plus, 1 part Mushroom compost, one cup dolopril Lime. I cant believe how quickly these suckers grow roots! It looked like it was almost root bound (although I'm sure its not) . The whole pot came out as one big root ball. I slightly loosened the soil around the roots as I put it in the new pot, then I just filled in around the sides and lightly patted it down. I watered with the same mix as before, but didnt soak the whole pot, just watered well around the roots and a little further out. Added some pics, check out my first 5 leaf set! haha.

Also another close up of my second seedling. still no change, however this morning i added about half a teaspoon of lime to the cup and tilled it in gently then gave a very light water...will be keeping a close eye on it as it looks like life might be hanging in the balance!View attachment 1622649View attachment 1622650View attachment 1622652

Did you say one cup of dolomite lime per 2 gallon pot? This is like three time the recomended dose! I feel this could be bad, too much cal/mag can present itself as iron deficiency, in fact i see more things causing the plant to show iron deficiency than an actual iron deficiency itself!

This also seems similar to the first problem when a seedling as well but am unsure with the weird markings, really yellow and strange.

I mixed up closer to 4 gallons, I made enough for 2 pots hoping the seedling would get going. In the end, I just transplanted both (but thats a story for another thread). I would have been roughly half a cup per pot. It does look like the same deficiency as before, only not as pronounced. I only thought in may be Iron def based on this chart that someone kindly linked just recently. Sorry I would give credit if I could remember who. Awesome chart for diagnosing!
 
Those last updated pics looks like a mag def but I don't know how your getting it so early in the plants life? Usually its during flowering so something is up with your soil.. Can I recommend Fox Farm Ocean Forest soil, I just switched over to it from promix and It's some pretty good shit.
 
Hmm with that amount of lime in soil it is still high but not as bad as i thought, half cup for two gallons, this is only like double the amount.

Is the pH staying at 7? Do you have to adjust soil pH or dose the lime keep it sweet??

Soil is steady at 7. Checked 3 times in the last week including right before posting this. Did you see what I mean abou the "finger mark" on the one leaf that looks a lot like the example of iron deficiency from that chart I posted?

I agree it also looks like it could be Mg def...but with the right PH, plenty of lime available, and mg in the food how could it possibly be mg deficient?
 
Hey dude, Pm me if I am right - and I may be able to help you, but have you already watered with nutes? I had done that to my youngest plants months ago and realized how stupid I am. If the nute water touches the young growth that will happen.

Just my 2 cents, I am NOT a well experienced grower but I am going through the same situation as you right now.

PM is on the way, but yes I have been feeding nutes. Also once every few days I have opted to foliar feed.
 
Leaf burn would look different. Maybe see how it grows and if it progresses. Deal with the ro water issue, maybe it is causing the problem even with cal/mag. I am gutted the problem has come back, look into the nutes as well or change them and see if any difference in growth is seen.
 
Carefull feeding nutes to soil and foliar feeding, discontinue foliar feeding for a week or two and see what happens.

The RO water has been gone for some time. Just using tap water which is PPM <100 PH 6.6. The only reason I began foliar feeding was to try and kick start it the first time. When I saw no nute burn using both watering with food and foliar, I just kept it up.
 
Latest update...LST is looking good, new growth is still coming in nice and strong. Starting to turn skywards again now just to let it grow a bit and the chain it down some more. (I'm giving some thought to making this a LST, SCROG and possible topping combo)

Today I decided it was time for a full flush. Ran about 5 gallons through it. Still not stressing, but it would be nice to see nothing but green for a change.
 
After the flush give it a few days and see if the condition worsens, maybe a week to recover and show more green.
