Hi guys! I'm having problem that I noticed on my plants on one plant leaves are yellow and curl on top, on other plants top of every leave is bit yellow pls. see the photos. I'm currently in flowering beginning of 6th week, temp is around 27,5C (80.6F) if you need more info pls. ask Thanks in advance!
need more info We need all the info on your grow including: What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info?
soil indoor 6 week flowering 30cm from 600w hps 6,2 ph of water today i fed them with mix of fertilizers (been feeding them four times in last two weeks) temp in room is around around 27,5C (80.6F) no bugs
looks like nute burn at first glance. what strength are you feeding? runoff ph? what size pots? did you transplant b4 flipping? the heat may not be helping but doubt it's the underlying issue
12 liter pots, i'm using mix of organic fertilizers from platiniumhydroponics.com; organic grow, alguamix, enzimax, PK 13/14 (mineral fertilizer) 1ml of every fertilizer on 1 liter of PH water. Now I'm in two last weeks before harvest so I'm thinking that maybe I will be feed them one more last time in few days.
looks like you got a bit more than 2 weeks left dunno what any of that stuff is, honestly. my$.02: ensure runoff ph is within range next watering, and start feeding bloom nutes until the buds swell. then begin flushing. i'd say 4-5 more weeks someone else will chime in who has experience with soil and/or those nutrients may be root bound
Looks like to me your burning your plant, try using a more diluted fertiliser and if it's 2 weeks before harvest I'd stop fertilising completely. Where are you getting your water from?
