Well, i have a 135W QB288 in a 2 x 2ft tent. Its only my 3rd grow so im still a rookie but i really dont think its a lack of light issue. This was my last grow with exactly the same set up: Cheers!

That didnt work, if anything the clawing got worse :( She has a tank of pH'd water no nutes. If it is N toxicity, i thought maybe the ppm would rise as the plant pukes out the N? It hasnt, ppm has stayed the same. I plan to give her 2 days flush. I dunno, ive been looking at my pumps and...

OK thanks. Its the same pump (Eheim 400) and 2 x 13cm air discs i used on my last grow which was fine, but yes from what you say i need more pumps. Cheers!

Is there any part of the pump that needs servicing/replacing?

Ok but supposing youve got an aeration issue in your tank, how would it show up in your grow? Cheers!

Ah ok i thought the idea was the bubles provide o2 directly to roots. Cheers!

Hi Im having a headache with a plant in a single DWC. I was checking it last night and i swear my pump is not producing as many bubbles as last grow. I checked the airstones, they seem fine, but i checked with 2 different pumps (both 4W) and theres just not many bubbles coming out, certainly not...

Many thanks guys. pH is under control. She got 500ppm of Cal Mag and PK13/14 so theres no N in there at them moment. If it is the N toxicity what should I look out for? Will the clawed leaves straighten up or should i just pay attention to the new growth?

She's had much higher humidity for almost 24 hours, no change :( Ive tried: Lowering temp of rez Raising humidity Dropping ppm down to 200 Raising lights (currently 24" from canopy) Checked airstones And nothing has made any difference. Very clear to naked eye are that the tips of stipules are a...

Many thanks!

Hi These arent pistils and they arent callyxes...so what are they called? Cheers!

The curling is as bad as ever. From GWE "Humidity is a factor that partly determines how much your plants will drink. If the air is dry, your plants will tend to drink more at their roots. If they’re already drinking more due to high temperatures, low humidity can cause them to drink a lot of...

PPM?

Just measured res temp, 75°...i know that is high, could that be the culprit?

Cheers, I ordered a humidifier today. Are bloom nutes lower in Nitrogen?

Just the standard HLG120H 48A, 135w. Each 2 foot EB strip 20w so 4 would bring me up to 215w. Maybe overkill, but the strips are cheap and i like building lights. Got 1.5g/w last grow so im curious to see if i can beat that :)

Ok thanks Greg. Yknow this started by me looking at the good deals on the Bridgelux Gen2 EB strips and i thought about adding some onto my QB. From what you guys have said seems like i might be better off doing that...?

Ok great much appreciated! How much of a difference would adding these leds make?

O Ok cheers yeah i noticed the tips further from the light seem healthier. Raised qb, its now 20" from canopy. Temps 25°, RH 35%. Thanks!

Ok thanks. Could you suggest another led? Im only just starting to look into this. Cheers!
