    I am at week 5 here in flowering... I've been feeding the plants at about a 1/4 dose of bloom nutes... I am getting some burn on other places on the plant, but doesn't look like anything on the buds themselves... is that normal, and should I keep blasting the plants and just say to hell with the rest of the plant?

    Thanks!!!

    i think it looks like they need some nitrogen, because i dont think there should be that much pale yellowing at this stage of flowering, although nitrogen deficiency is perfectly normal mid to late flowering.

    top up with a bit of veg nutes at quarter strength or about, perhaps use slightly more bloom nutes aswell if you want. soil or hydro??

    anyone correct me if im wrong?

    that is definately not nute burn, especially since your only feeding quarter strength blooom nutes that contain probably hardly any N.

    nice plants tho

    thanks for responding guys... do you know why the tips of the leaves are so fried?

    I thought it was a N-Deficency too, but I didn't want to trash the buds just to make the rest of the plant look ok... I am mostly worried about the tips of the leaves being brown...

    It doesnt look like natural N defiecency, i dont understand how you say it isnt on the buds when clearly the samll leaf structure around the buds is affected. 5 weeks flowering you shouldnt see that much yellowing in my experience. YOu could get better help if you could describe your setup, soil or hydro, what e.c are you feeding with, what is the ph, and what has your feeding schedule been could there be some salt buildup if so just water with regular ph'd water next time with no nutes.

    Yeah, you're right... I didn't notice that one bud... its pretty bad on that one...

    Setup:
    Soil (Fox Farms Ocean Forest)
    Tiger Bloom Nutes (1/4 dose)
    pH of the water is 6.3
    pH of the soil when I checked the runoff about 4 days ago was 7.1...
    I flushed them over the weekend with just pHed water and the nutes started again today w/Superthrive (normal 1cc/gal does)
    The watering schedule is every 42 hours... it's automated on a drip irrigation system I built... soil is draining nicely as well...

    A couple weeks ago I went on vacation and there was a slight malfunction with the irrigation system and they were given too much water so they were sitting in their runoff for a few days before I came home and cleaned them up... I figured it was nute burn because they were sitting in that nuted water... but it's not exactly going away, so I'm a little concerned.

    So you're thinking the mess is a deficency? I am just terrified here, I can see the promised land and they didn't tell me it would have brown and death all over it... :(

    Here's a couple new pics of a bud with brown issues...

    Right now I have them on 1/4 strength Tiger Bloom, 1ml/gal of SuperThrive, 1/2tsp Molasass... I built a drip irrigation system to help me when I go out of town that feeds them 4 times a week (every 42 hours)... everytime it feeds about 750ml of water go into the soil.

    Thanks!

    For get the superthrive. Its used for stress like after transplanting. Probably not the problem just not good. If they are not green they are hungry as a rule.

    Having experienced some nute burn before the crispy tips were making me nervous, they looked exactly like the plants I had before that were overfed...

    yes they are watered 4 times a week, just about every 2 days... I've been doing that since I started, it's just enough time for them to drain out and dry up a little before they get wet again...

    yes, I flushed them yesterday... and the molasass is something I've read on several occasions is good for bud size... and it's molasass, or sugar, so I am not worried about that...

    id give them more flushes only water, give it a couple days and see how they look. if nothing happens back to your veggie nutes or something high in nitrogen. but damn looks like nute burn

    I am questionable about your irrigation system, i understand if you are out of town but while you are home i would suggest taking it out and just watering when soil is dry, looks like you could use some phosphorus in those plants. I would also up my ph of watering nutes to 6.5 - 6.8 unless your soil runoff is still in the low 7's. I have used mollasses in my soil grows as well sometimes through the whole life cycle. And have had excellent results. ( you should be careful with mollasses because some have magnesium and iron which is ok but those are micronutrients and you will need less of these nutes than you think but i always used more than you do anyways so probably not your problem. Before i added any nutes to a plant that looks like that is to flush really well and dont add anything else until soil is dry, then start your nutes over from scratch slowly increasing the dose to you find the dose that your plant likes best, then once you have that down alternate with plain water.

    well if they only flower for two months I've only really got two weeks left on the nutes anyway... what do you think about switching to just water and the molassas and calling it a day?
