First grow, switched to flower 4 weeks ago. A week or so ago I noticed brown spots on the leaves. I assumed calmag would fix problem.now leaves are dying off a bit and the buds are coming in nicely I don’t want to ruin my yield. Fox farm ocean forest soil, ph runoff was 6.5. Temp and humidity is controlled. Soil seems to be getting hard in 5 gallon fabric pots.seem to be drinking a lot. Wondering if possibly getting rootbound could cause the same symptoms?
Welcome, looks good I think your on the right track but imm pretty sure root bound is not an issue with fabric pots. The roots grow through the bag and air prune themselves
Just worried about the leaves dying off. Im hoping the worst is over and the deficiency has been corrected. Was hoping someone went through this already and knows what deficiency caused it or if my light was too strong…
As rare as it is. It looks like manganese to me. Best wait for more experience though.
I do not think the problem is caused by bound roots. One benefit of fabric pots is some root pruning. The condition you are experiencing looks very similar to one I am contending with. These are purple haze.
I first noticed it 6/20 day 28 on 12/12 light schedule. Taller plant upper left leaves. A few brown spots.
You said you are in FF ocean forest with runoff ph of 6.5. Normally I would think this is acceptable.
Did u happen to do a water to runoff and catch some to check numbers. Seems likeeither mag problem like stated or possibly a ph lockout. If u r too rich on one of the nutes u r feeding it will cause this problem also. Best wait for a def more experienced person to give the word tho. I muself would just water super good with phd calmag water til i get descent number coming out.
What nutes are you using and how much?
I’m using fox farm nutrients. Not at full strength, although the ppm was 1700 and I use R.O. water. I basically stopped feeding for now all I did was water with calmag at a ph of 6.9 so I’m hoping to se some better results. Then I plan on keeping my ppm at around 1000… and I appreciate all the helpful comments.
I did start giving them the open sesame and beastie bloomz according to their schedule, just not at full strength. Maybe it was still too much…
After a water or 2 check run off again. Once u r down to desired ppms ur in good again as long as ph is there too. U can feed at higher rater but u really have to watch the plant and dont up it alot at once gradually up it. If u notice tip burns at all fo a water and next feed dont go as high of ppms. Always alway always keep ph in line. @Hellraiser is gonna be a hell of a leader for u. Just look at his journals lol
Seems like a combination of current nute burn and maybe prior deficiencies. Are you flushing as per the FF feed schedule, every 3-4 weeks? I always had issues with FF trio if I did not flush now and then. If not, I’d give them a good flush and re-feed at 1/2 strength, don’t want to leave them hungry.
I did flush with the sledgehammer as per their schedule. But I hear what you’re saying. Sounds accurate, I definitely went about 3/4 strength if their recommendations but I probably should’ve started at 1/4 strength and gaged the plants response.
hopefully they recover and it doesn’t hurt my yield too much. Thanks a lot, I thought it knew what it was but it being my first grow I felt like I definitely needed some guidance. This site is great. Thanks a million!
And on another note I was thinking about going 100% organic with my nutrients next grow. Any suggestions on brands? Sorry to bother just wanna grow the best buds I can.
I used and recommend advanced nutrients Iguana Juice Grow & Bloom. AN was supposed to be rebranding and adding to its organic line. Not sure where they are at in that process. I did a combination of organic and natural nutrients and supplements.
