Hey Jesperado... you don't have a diary going for this grow! Any answers you get are therefore going to only be guesses and I'm guessing nitrogen toxicity... But I don't know what you're feeding or in what amounts.. Do yourself a favor and start a diary for this - that way, it helps us help you! Good luck!

yeah it does look like a nitrogen deficiency (yellowing) as well as the beggining of a potassium deficiency (brown spot): https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

Burnt tips and yellowing leaves About two week ago, lower leaves started yellowing, and I saw burn leave tips, so I suspected nutrient burn. I only watered with tap 6.5 pHed water since, but the burnt tips and yellowing are getting worse continuously. At least 3 largest lower leaves died off over the period.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Yellow and fragile leaves 2 week Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

If this was yours, how would you proceed?Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!

What are these yellow/brown dots and how can I prevent more from developing?Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.
