SSFito173started grow question 5y ago
First week of flower and this starts happening. I flushed with 1 gallon r/o water hopefully it doesn’t continue. Anyone knows what deficiency is this?

It look like light burn or a micro nutrient deficiency (magnesium, copper etc).
If your lights are the proper distance and your feeding the plants a well rounded diet, then i would double check your ph pen is accurate. Recalibrate it if possible. You may be having ph swings too low or too high.
Happy growing. ✌️

Was haben meine Pflanzen?Liebe Community,
Neuling hier :)
Ich habe zwei Critical Kush Auto in der 7ten Woche die seit der Blüte eine leichte Nekrose/Verfärbte Blätter haben.
Leider habe ich vor 3 Tagen erst das erste mal mit Hesi Bloom gedüngt 5ml/L, vorher noch garnicht.
Mehr Düngen? weniger Licht?

brown spots sugar leavesI've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?Week 7

Brown/Grey spots on the leavesHey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Brown patches on leavesNoticed these marks on the leaves of the plant I've had problems with.
Any ideas what they could be?
The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again

Ongoing brown and yellow patches forming in week 6 of flowerI've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)
