First time grower, running into some issues

Hey guys, it’s my first time growing. For some background I’m running the build a soil 3.0 and light mix soil(50/50), fabric 5 gallon pots, Kind LED 200W. I started getting some random yellow leaves, almost overnight that get real ugly and pull off with 0 effort. I’m about a month into flowering with the northern light auto from ilgm, and I’ll attach some pics.


Check your ph


Welcome to your new happy place :blush:
Have u checked the ph in and runoff?
What nutes have u used?

Some of the deficiencies you may get in flowering are iron def , potassium and phosphorus def and calcium and magnesium def now to me it looks like a magnesium def some cal/mag should fix the problem or u can use Epsom salt i will have a look on the internet to get a better confirmation of what type of def u have i will get back to you soon

If it happened rite after you fed her nutes, you’ve probably got nutrient burn. If so, flush her and it will stop. Pull off the affected leaves.

I used the Build A Soil fertilizer, the top dress amendment, and the build a bloom. The yellowing didn’t follow after feeding (everything except the build a bloom is slow release amendments anyway) and I’ve only done light amending since the BAS 3.0 is pre amended with everything from the fertilizer and top dress. When I first noticed it happening I corrected PH but it didn’t seem to fix the issue. Temperature and environment are in check as well.

I appreciate the thought! I am running living soil and organically, so I’d have to look into using cal-mag. As far as the epsom salt goes I believe the build a bloom has it in there! I did only recently give them a feed of that about 3 days ago so it might be a bit soon to tell if it’s helped.

Foliar spray calmag. The Earth Dust some of us use suggest a foliar if calmag issues. In flower so doing it at night not as cool. I would go with lights on to dry them fast.

I thought you weren’t supposed to foliar spray anything in flower?

Not recommended normally. Earth Dust is living soil. That is what they suggest. I follow their advice. This stuff is a boss.

Well if a calcium or magnesium was the issue and epsom salt helps, the build a bloom has horticultural epsom, and I applied it 3-4 days ago. So I guess it’s a waiting game to see if anything new yellows lol

When did you start your flower clock? They look a lot mature for 4 week flowers. May just be the pictures. Also, did you check your soil PH? And what were the NPK on your fertilizers? For instance 2-8-4.

To me. It looks like you have a girl that is somewhere around 6 weeks flower. Normally you would start the clock the instance you see Pistils. . … it looks like she’s trying to exhaust all the nutrients and chlorophyll for her in preparation for her death/harvest. I could be way off though.

Another indicator is she has pistils that are turning amber color. I would wait before you spray or add anything else. Maybe within the next day or so. Some others may chime in. But I see a girl building trichomes, and exhausting herself…… from my studies is that indicates a later flowering girl. And if she is that late into flower. You don’t want to add anymore nutrients at this point.

I agree give it a little while then see if u need to do anything else

I haven’t checked the Ph of the soil, just the water I put in (which has only been for the last few watering they didn’t have any problems until flower, so I didn’t adjust PH in the beginning). I started flower on March 1, so right around 5 weeks. The NPK of the craft blend fertilizer is 3-5-2, and the Build a bloom is 2-10-5.

I would leave her alone at this point. Did you just add the nutrients? Also, do you have a magnifying loupe to check the trichomes on the buds. I think you’re about 2 weeks till you can harvest her, and if some of the veterans here would agree. I would be contemplating a dechlorinated un-PH’d flush in these next 10 days or so. Please keep us updated. The thing with autos. Is, she could’ve shown pistils for a week or so before you saw them. And a true indication of where she’s at. Would be to examine the trichomes inside the flower to see what stage they’re in. Clear/Cloudy/Mostly Cloudy with amber heads. . If you don’t have one. Get a 45X Magnifying Loupe from Amazon.
