Looking for some advice as to how to deal with plants showing severe signs of what has been diagnosed as Sulpur and /or Magnesium deficiency on new growth. The symptoms are due to imobile nutrients or secondary nute lockout (Mg,Ca,Su,Fe). The damage was caused over the last two weeks while trialing a new microbial/root repair product which has not been released (what a fuck up!). The product was first applied 1 week before going 12/12. It was used for two weeks. After the symptoms became too severe (at the end of the first week of 12/12), the system (rockwool) was flushed with plain ph'd water for 2 days, then the tank was dumped again and has been run on A+B bloom nu…

what strength nutes should i used to foliar feed? using DM penetrator as well i tried it at 700 ppm (1lt from the nute tank premixed and 1lt plain water) with the recommended dose of DM penetrator (20ml per litre) did this and repeated 2 days after. a few days later i noticed discolouration around the top canopy (particular new growth) of a kind i have never seen before i have foliar fed at 700 ppm before withough DM penetrator with no problems like this should u use a lower dose nute mix with DM penetrator (or is the DM penetrator a shit product and should i just not use it!) thanks

Hi team, I am using an autopot system, dutch master advanced nutes, 250W MH about 3 weeks veging. I did let the pH get to 7 about a week ago but have since brought it down to 6. Anyway, the outside edges of the leaves seem to be curling up and the leaves feel a little dry / brittle. I do not think it is a heat problem (has been cool here) and the light is sar enough away. The globe is new! All help appreciated! Cheers

Am i the only person in australia with invincible scarid fly? ive researched for hours on ways to kill them and ive tried EVERYthing on them. microbial is useless ive bought litres and litres of this shit but no luck. ive tried watering it several ways, like hand feed and drip feed at diff dose rate with np luck, ive even tried daily misting of the top of the media with straight microbial. i read on ostoners from luke that success drench works but after 2 drenches a week apart at 5 ml per litre that didnt work. ive tried a layer of clay balls on top also tried a layer of perlite with no luck. cutting back on feeds mesh on inlet fans sticky fly traps (dozens) under…

The lowest leaves on my plants are turning yellow, what does this mean?. Is it lack of Nutes?. I didn't add any nutes untill the 3rd week. I'm using Thrive at half strenth. Gave it a dose 6 days ago again just now. I hope I'm not over feeding them?. They're watered every 36-48 hours. About 100-150ml.

Hello all, I've got a plant problem that has me stumped so far and I'd like some assistance. My White-Skunk plant has "bleached" looking new-growth, the new leaves are not nearly as dark green and lush as the older growth. The symptom started showing itself after I transferred the plants from my 400wMH vet area to my 2x600wHPS flower-box. I originally thought it was light-bleaching, or the fact the plants were transplanted into a larger pot with a coco/perlite mix where the perlite had been washed in a strong oxy-plus solution. Unfortunately it seems I am incorrect, as the problem has been here for well over 2 weeks now and my attempts (flushing, lowering-PH to 6.0) h…

hi does anyone have some pics or a resource of the signs of underwatering? i can find heaps on overwatering but not much on the other? apparently from what i have read the visual signs are quite similar (drooping leaves?) another thing i read is that plants that are overwatered will droop at the tips of the leaves and the stems stay upright? but an underwatered plant will droop both leaves and stems? thanks
