Leaves yellowing too fast in flower?

Married2MarryJ · Feb 9, 2018

hey guys so I have an ethos genetics rainmaker and she’s 36 Days in flower her bottom leaves are yellowing and her top leaves are lighter green but now turning purple. I have been feed water feed water. Are the leaves yellow too fast or is this natural?

It's a little early for that much. Looking closely at the pics I can see some burnt tips and clawed leaves here and there which would be nitrogen toxicity, and a few other things some more experienced members on here could pinpoint for you better than I can.

I used to get this a lot around the same time as you are seeing it. I added cal mag pro to my feeding schedule and it all stopped

That looks like lockout, I doubt its deficient... That's a big plant for such a small container. You must feed it a lot yeah? It's probably got salt buildup. Do you have access to RO water?

I was thinking of purchasing cal mag. It’s a 5 gal Lowe’s bucket it I vegged it for 8 weeks.

I have been feeding it this crap fox farm bloom nutrients and mammoth p i just feel the plant wants more those bites probably aren’t best. Feeding At ph of 5.8 is that too low? I just got blue planet nutrients I’m ditching the fox farm nutrients but hmm I wonder what this is

5.8 is for hydroponics bro

Word man in my first grow this didn’t happen but she’s been through some stress also.

I would say that big enough if my calculations are right that’s about 20 litres. I use 22 litres and grow happy healthy 6 footers and beyond

It’s lockout from ph to low bro there’s other charts that are more simple to understand I will find 1 quick

Am I too late it will some cal mag and ph fix this problem?

Your first grow was great. WWxAK

Might have early fade on that one, but she's very well developed for 36 days. That's a tough look, under fed maybe.

Pretty sure it’s fine. It’s drawing resources from leaves to out into the bud. Probably another 20-30 days, roughly.

What's your substrate? I'd recommend flushing with appropriately pH'd water. There's definitely a nitrogen toxicity there, I've dealt with similar around the same time but have found a flush every two weeks or so does the trick. You'll still get some good bud but your yield will be diminished for sure.

That definitely doesn’t look N tox’d. It would be dark green and curling.

It’s clawing. Doesn’t necessarily mean N tox. The leaves are way too light for it to be that. It’s probably clawing because it’s fading.

Are you using Pure Ocean Forest?

pH won’t matter as much in organics. That isn’t lockout from pH.
