Correct, I flushed to see if it would stop burning at first, carried on so I added in bloom food. That went terribly causing more burn. Would checking runoff be good for pH testing? They're not brittle so I guess it just decided there was too much nutrient after I'd trimmed a few days prior. I'm...

I fed them last night wondering if it was potassium deficiency but the symptoms are even worse this morning. Dosed 3ml bloom 3 ml micro in 1 litre of water. It came out at 700ppm. My tallest plant is 19 inches. The smaller one I have seems fine, a little bit burnt but fine. Strange to think this...

Not entirely sure. I guess it could be calcium raising the PH high enough to cause a lockout. Make sure if you're in veg to only feed grow and micro. Another grower also suggesting adding a tiny bit of bloom in their but I've ran grow and micro fine before (jungle juice nutrients), it stopped...

I've just been giving them tap water for the last few weeks though, this started after I trimmed some excess leafs off and so on. It's only around the top of the plant. Flushed the other night, wondering if it was nutrient burn and its now looking deficient and getting worse faster. Just noticed...

Every 2 days are you kidding me lol. Feed them once, wait a week or two until signs of deficiency show again. Be patient.. and keep notes of what works and what doesn't. Besides that leave them alone under the light.

Why has nobody mentioned zinc deficiency? It could be to do with your root zone if you're feeding them with micro nutrients as well. My plants were like that in DWC when they got root rot.

I just wonder why the issues are now? I'm in week 3 of flower.

Hi guys, my plants have been doing pretty good up until now, growing in soil labeled as PH 6.0. Fed this plant 2 weeks ago with bloom and micro nutrients and it's been going great but this issue on my upper leaves is getting progressively worse - I don't know whether to feed them again or so if...

Thanks buddy will get some ordered.

Okay think I will. The lights are off and have bleached my reservoir twice and now just running tap water and hydrogen peroxide. Gonna bleach the res tomorrow again im thinking

I've been struggling to find h202 any higher than 3% :/ anyone got a link to? If planting means I can flower them then I'm up for it but wouldn't pythium take hold in the soil? Will try that with the h202. I forgot to ask should I even be adding nutrients at the moment?

So my have been flourishing since I sorted the feeding schedule out, but one problem - root rot. I've been putting ice packs under the bucket to keep it cool, tried lights off for 24 hours, checked for light leaks, scrubbed the reservoir, boiled it, bleached it, changed the air stone and line...

Looks similar to phosphorus deficiency. Don't take my word for it (as in don't feed them with it before doing more research) but I did read that yellowing edges like yours are phosphorus def.

So am I right in saying you dont supplement with bloom nutrients during veg? I've been doing that for a while and all the plants I've tried to grow have died apart from the one grow. Oldmeduser I just realised what I said previously is roughly what you're saying. Little misleading it states on...

Just realised bloom is only adding extra salts and some magnesium. the other two have the same nutrients in - I think the idea was to switch from grow to bloom with micro during flower. Had read that these plants excrete salt through their leaves thus nute burn. Mixed just grow and micro now and...

Thanks Oldmeduser. I'll mix less in of bloom and give it a try. Have bought a new TDS meter which cost £30 on ebay. So it should be reasonably accurate, a little tight on money. Here's the link - ( http://www.ebay.co.uk/itm/391549041469?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT )...

Sorry I meant will check out the sensi grow line :)

Yeah my problem always seems to be with feeding the plants properly and I've read a few places too that jungle juice has been troublesome for most too, so I agree with you there. I'm gonna invest in a decent tds meter and some new nutrients I think. They used to drop my ph when mixing them but...

Hi guys, the roots are growing very slowly on 2 out of 3 plants despite them being healthy with no slime, algae etc. They're a nice white colour, at the moment I have no way of measuring res temperature, had been having quite large ppm swings before I set the ppms in my bucket to 200, its raised...

Hi guys, with further though I believe I might have a faulty ppm meter. It was quite cheap from China so, 400ppm in total - sorry should have been clear. I wasn't sure if any other nutrients were being overdone, I noticed nitrogen toxicity but wasn't entirely sure if it was the strain or...
