hey a week ago my plants strated to show brown spots on leafs and on the leaf tip, they r in soil 12 liter buckets, i water them every 2-3 days and feed them every week with 1/4 strength canna terrra vega, im carefull not to overdo the ferts since ive had problems b4, so i wonder if its lack of nutes or a lockout...

hi m8
Dont act on anything i say(Wait for the others to chip in some answers)

It does Look tho like a slight lack of N(the yellowing(Leeching colour)Of the fan leaves....Normally this happens towards the end of flowering(last few weeks)as we dont use a High N value feed(well i dont)
It looks tho like your still in veg tho?

So for that reason i would think your not givin it enough N

AS i say dont do anything to rectify this from what i have said
Wait for more info


While your waiting have a look in the sticky links at top of this section
Is a lot of pictures in there(with there problems)
Could see a plant with leaves like yours(And the reason/fix for it))

Make that 3 votes for N def...doesn't look like any burn on the leaves, so lockout is probably not an issue unless you've had some crazy PH swings lately (but there's no spotting on the leaves yet if that's the case).

Some ready made mixes like promix potting soil may contain a starter charge. This is a liquid plant food that is sprayed on the soil. If your new soil contains this starter you may skip fertilizing one time and use straight water. Transplanting should be done when they are rootbound not because they are missing some nutrients. You can just add more nutrients or whatever to the old soil. If your new potting soil you are using does not contain dolomite lime, I might add some. Also, you could mix in some gypsum to supply sulfur. Check the bag to see what it contains. You should be adjusting your fertilizer plus water ph to 5.6 to 6.2 when using soilless mixes for potting soil.

Tbh m8 i dont think i would transplant(again the others will know more)

Like if you transplant you will have to move the screen(possibly untying it so on)
And your plants are not in that bad a shape

If it was me i would just use a high N feed(Maybe somit like 3-1-1)
And use that feed for the next month....I say a month coz u plan to veg another 2 week,and plants normally like u to keep the hi N feed for the first few weeks of flower.....
Also then never exede the dose they suggest(but i know u aint anyway)



Bottom line for me
Your ok
Plants are doing ok
No rush to fix this
try and use a simply fix(rather than creating stress/lock out probs)

re pot now and take the screen with you... this also gives you the time to trim away any growth that is not productive.

You may slowly up ur feeding, also root stimutalor helps plants take in nutes a little better.

GroDoc is right a transplant would do the trick. Before I transplanted I would flush really good since you look like you will have a large root ball. None of this can hurt it can only help. Even if your doesn't really look all that stressed. I mean you have nice growth, it could be just survival of the fittest.

How often do you let the soil get dry. This can happen if you let the soil get to dry also. Good Luck

Mo,

hey,

i use chemical feed and npk 14-6-17 i also have amonium nitrate, well i think it would be best to repot cause roots r popping out of the top soil and i would have the space for it in the flower room... the screen would go away they where used to keep them low for the veg box... and a new screen that would be 1x1 meter, over 6 plants.
no they dont dry out often.... i do it once a while

a week since transplant.. i also uped the feed and they got more color, 4 days ago they where set in the flower box under a 400 w hps about 60 cm from tops (been under 70 w tubes b4)... also been some temperature swings in this last week but new shots r light green and some yellow.. also some rusty spots on some older leafs.. so is this maybe ph-problem or maybe caused byg the light switch from fl.tube to hps or do they still need more ferts. they r stil in veg(24 our light).. this is my first run in that box. dont wont to set on 12/12 lights b4 plants r looking good...
ill get the ph checked... and will post it later... ph of my tap water is 7
