Too much nitrogen. Excessive mineral salts in your growing media. Ease up on the feeding would be my advice. Go to half strength.

Can anyone help identify this tox/deficiency?Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

I have been having trouble with my leaf tips and edges appearing yellow and then turning brown. At first it was just the bottom leaves that were affected but now more of the top leaves have the burnt appearance just not as extreme as the lower leaves. What can I do to fix this?

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

I have 2 feeds left before I start the 3 week flush. With the state of the nutrient burn, do you think I should start flush now? Or feed half usual nutes for the last 2 feeds? Her leaves will die anyway during flush so that why I'm not so well worried about the nutrient burn.

FEEDING PISS Hi, I've been feeding with piss mixed with water my plants (1/20 parts ratio). At beginning of flowering stage I started feeding them less piss and more Flora Bloom GHE for more K. Is it true there is ammonium in the piss? Is it bad for the plant?

Dear ganja gurus, please have a look at my diary Wk17 D119. I'm thinking nute lockout due to pH always below 5.8. But any other inputs is most welcome. Nute is 50 ppm epsom, 100ppm CaNO3, 100 ppm MKP, and topped with 7-5-16 A/B to 900ppm.

Well I added 280 ppm nutes and she showed signs of burn and the leaves dropped. I lowered the ppm to 200. Is that good enough? It's a very small amount of brown around the edges but I dont want it to get bad.

Leaves burn Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

I still can’t determine whether this is a heat related or Nute burn issue. Is it that temps are too high causing a Nute problem? I’ve done all I can to lower temps.
