Chart 1 indicates that in soil (on the right side) that the pH range for Mn and Fe uptake ends at 6.5 whereas in the second chart Mn goes straight through from 5 - 7.5 and Fe up to 7. Reason I'm asking is because every pH test I've done so far comes has been on the high end around 6.8 - 7 and...

Turns out it was a magnesium deficiency.

Haven't seen any but will keep an eye out for it thanks. We have a strong agricultural industry here so we have domestic brands but haven't come across any well-known brands.

Yeah the pots are big... Thought it'd be a good idea after reading that some people do it that way and not have to worry about transplanting but I won't be doing it again. Using normal tap water that sits for a while to let any chlorine evaporate. pH of run off is between 6.5 and 7. They've been...

Surprised that no one mentioned this... Further research suggests that it's actually a cal/mag deficiency. My plant followed by example of Mag deficiency:

It's a hot winters day today so figured I'd put them outside for a while. Temps are a bit high around 83f, is that ok, I mean it's only natural right? They look beautiful dispite the problems and I can't stop myself from looking at them every few hours and posting some pics :)

Ok I think I can make a few conclusions now and the first reply from cannabisweedPotNerd which said "looks hungry" was on the money, though some elaboration would've be helpful. Instead of just feeding it I want to learn the signs as best I can now in my first grow and be able to differentiate...

Yeah looking at other grow journals all my plants are a bit behind and this one is way behind... lessons learned.

Gonna let it recover in the small pot and then transplant back into the big pot I reckon unless there are any objections?

Hahaha you would be correct haha. Early stretch in the first few days after sprouting but the other 2 seem to be doing alright apart from the N deficiency which I agree with you on. I just watered without nutes though so hopefully the fresh soil that was on top will provide some nutes untill the...

You may and no I haven't... Total newb.

Ok I pruned the roots and the worst leaves but by cutting through the leaf and not the branch except the lowest 1. Not sure what we can tell from the roots?

I will do and will report back. Thanks, really appreciate it.

If only it was that easy...... It's winter here at the moment and our high court passed judgement that it was unconstitutional to forbid the cultivation and use of marijuana within a private home. The government is now appealing the judgement and it's going to the Constitutional court at the end...

Thanks! I thought this might be the case :)

I've put a lot of effort into taking a more patient approach because I've come across the same suggestions everywhere about over watering, nute-ing etc. When I thought they were dry a few days ago I told myself to wait as long as I can but with the drooping leaves and spots that's why I decided...

Thanks. I've definitely added a few things to my shopping list. Yeah it's hard to treat the problem if I can't identify what's going on. These were planted directly into large pots because I didn't want to mess around too much with transplanting being a newb but it probably would've been the...

Thanks for the tips and link I'll check it out. Regarding the 22-7-14 nutes: I have fed and watered really really lightly for fear of over watering or burning and because the lower leaves are a bit yellow and that septoria apparently shows up in N deficient plants this is why I'm thinking that...

I'm treating it as septoria and N deficiency. I took the really sick one out of the room and used some baking soda foliar spray on the lower leaves of the other plant as that's what I have on hand at the moment. If the spots progress i'll prune the leaves although I hope it won't come to that...

Before planting I read that dolomite lime can take months to breakdown in the soil so what I did was mix the soil and dolomite about a month before planting and watered it. Thing is is that I didn't have any perlite yet so it stayed wet for quite a while. Maybe that caused a fungus to grow in...
