Regular Old Deficiency?? (pics) - Cannabis Infirmary - International Cannagraphic Magazine Forums

gOurd^jr. · 02-16-2006, 06:04 AM

Well I've been running the gamut of nutrient problems throughout my first few grows and I really want to be done with it all. Here are some shots of some new seedlings of mine showing symptoms I've seen in about all my grows so far. The yellowing of the Oldest true leaves is Classic N deficiency saying this babies are ready for some food right? Do the dying tips on the seedling in the second picture look like its getting P deficient as well? Help much appreciated.
peace and pot

I would say yes to N def. They are screaming "Feed me Seymore"

I would folier feed them at a 1/4 strenght soon.

What is your soil(less) mix you are using?

PS: when you see the seed leaves (cotyldons)(sp) getting yellow it is time to start feeding them.

Oh yea the soil is mostly potting soil with a bit of compost and lots of perlite. Gravel on top for mulch to keep moisture in and prevent compaction from watering works like a charm! plants shown are Captain Beefhearts Black Thai on the right 4 and the other two are Subcool's fiesta mix and Spice Bro.s c99xBlueberry Sat.

The leaf tips looks like dying... is that usual for N def really? If it is maybe it's my plant's only trouble... I'm puzzled

Is it too early to ask about ph?

m.steelers · 02-18-2006, 07:32 AM

Those look N deficient to me, probably some other deficiency mixed in too. You should be checking ph if you arent - 6.3 is what I like in soil and pro mix. But deifinitely hit them with some ferts now, phd to 6.3, they might get worse before they get better depending on how quick your ferts act.

This happened to me alot, I'd get some cuts and not feed them soon enough because I was worried about them being too young and boom, a deficiency shows up. Set you back a couple weeks. I have learned that when using organic ferts it is much more difficult to burn your plants, so therefore you can feed your plants sooner and ultimately avoid these annoyances.

I've had this same problem when using to much perlite ...had to step up the N twice as much....I backed off the perlite and was fine

gOurd^jr. · 02-20-2006, 07:28 PM

Well I've transplanted them into half gallon containers with a bit of a new mix in it that I'm trying out. about 50% coco coir, 10%perlite,20%wormcastings, 20% planting compost. More or less. Didn't have time to let the mix sit so I didn't add the usual organics like guano and such. Also watered them with some guano and kelp tea. They're holding steady although a couple are getting a tad worse I'm sure they'll rebound soon.

this doesn't look like a N def to me

yellow tips? i'd say burned

what was in your compost?

02-20-2006, 08:17 PM

A high perlite mix means less N from the compost/soiless mix plus the volume from the stones, soil gardeners generally don't have to feed them this early but a high porosity mix means two things, roots develop faster and nutrients get washed out of the mix faster to a degree.
You did what I would have recommended, you transplanted them into more mix.
I grow in coco so beware of calium def's they occur frequently in coco, do an initial wash of a calcium supplement solution to wash excess potassium from the starter mix and ammend your water source with extra calcium and magnesium as the coco web tends to binnd up these elements. (botanicare calmag works fine).
