Please help.....brown tips on my girls

Hey people, any knowledgeable peeps tell me what is going on....

she's 5 months old
growing outdoors
was feeding her fish emulsion and seaweed concentrate. (brown tips appeared while on this feeding cycle around 1 month ago)
started her on Yates Thrive soluble flower and fruit fert 1 week ago but no change.

plant looks healthy in other respects and buds are forming. im worried because these brown tips are on the new leaf growth too....

Please help, i dont want to loose my crop over a stupid mistake i might have made....

how much of that fert did you use and how many times have you used it so far? has it been raining alot where you live lately? what are your temps during the day and during the night?

For the ferts I used the manufacturers recomended dosage once a week with the fish emulsion and seaweed. last week i began feeding it the Yates.

It has been raining a bit and combined with me watering them every day or every other day, (maybe overdoing it a bit?) im growing in sydney so temps are high at the moment 30+ most days and warm nights.
thanks for replying

first day of rain or atleast hr isnt that great water

might have ph problem at the moment...

You think ph? ill have to buy a tester, been meaning to get one

thanks for your suggestion

it could be lots of things, it can be kinda hard to tell, it may be a combination of several factors(which i think it may be, since nothing other than it might be getting too much water sticks out but you have had the problem for a while you said)has it been raining ALOT alot? with the ferts you want to kinda get em used to em b4 you go and give em full doses or more. i'd try watering it less and maybe see if that helps.

Man, that's so weird because they look so healthy other wise. The brown tips kill the beautiful aesthetic... I agree that it could be a combo of problems... Now that you're getting more rain, you may want to check your run off pH. There could be a problem there. But I'm actually thinking it could be one or two things specifically. My first guess would be a slight nutrient burn of some sort. When the plant flowers, it wants more of certain nutes, and less of others. Did you change your nutes once flowering started? If not, the plant could be getting too much of one type of nutrient now. My second guess would be heat stress. The tips of the leaves are so small, maybe the hot temps are burning them. But this doesn't seem quite as likely as nute burn. Those are my guesses.

I think you should switch to a flowering specific nutrient and see if that helps... If you haven't already.. Good luck to you.

brown leaf tips usually means your feeding them a little too hot of a mix. drop it down a couple hundred ppm and they should be fine. i always have some brown tips here and there....

Check ph first then if thats not it I would flush and adjust your fert. I had the same problem and it was'nt ph it was over fert so I flushed and it fixed it

Thanks to everyone for the suggestions. I checked the ph and its hovering 7........it could be heat stress like snutter said there in full ozzy uv delight sun all day but i have a few more and there all fine.

I tried using a flowering fert last week so its only had one session on the new stuff. Before that i was giving it fish emulsion and seaweed at the full recommended doses for veggies and plants.

The brown tips appeared months ago so i dont think its over ferting on the new stuff.

Im wondering about the water. Im checking the pots to feel how heavy they are before watering now but for a long time i was watering it till water came out of the bottom of the pots every day or every other day. maybe it was too much. If i try not watering how will i know if its working, surely the leaf tips will remain brown?

It may rain soon i have a plastic roofed varander type thing should i put her under that to get her out of the sun and rain? will it not need more light than that?

Thanks agian to everyones replys

peace

checking run-off feed in soil is pretty useless. you won't get a true reading. you'll be getting a reading on the built-up nutes in the medium. as long as you ph "everything" you put in/on a plant, ph should never be an issue. it's not overwatering, LOL, overwatering causes a plant to droop, not get brown tips....

All four of my little girls have some leaves that are drying out an crumbling off. my ph is 5.8(uses ph controller) run in a bubbleponics system under a 400w mh... and haven't used nuts yet due to the young age of my plants

I think its over ferting thats gradually built up over time. im gonna flush the girl and see what happens, ill report back for anyone else in the same situation

I'd also stop with the fish emulsion. It's very high in organic nitrogen. Don't feed them anything for at least a week, only clear water.
