Hope someone can give me some help and advice about the problems I’m experiencing. A little background first. I’m not a total noob on growing pot. I’ve been growing for 5+ years. I started with bag seed grown in peat, composted horse manure, and perlite. I used homemade lights made from off the shelf led bulbs from Walmart.So Pot was good, yield was decent…so this worked out OK. After a few years, my seeds started to become non-viable ( due to age). Decided to buy some seeds with known good genetics from ILGM. I decided to use Fox Farms Happy Frog soil with Big Bloom, Grow Big, and Tiger Bloom. Germinated seeds sucessfully and when big enough, transplanted them to 4 gallon containers. No fertilizer whatsoever was used at this time. After about 20 days, I noticed a couple of brown spots on 2 plants. I Thought it was time for a little nutrients. I mixed 1/2 tsp Big Bloom, 1/4 tsp Grow Big, and 1/8 tsp cal-mag with 1 gal of water split between 4 plants. Really a reduced amount of nutrients based on chart or bottle. Next day the brown spots had multiplied and leaf edges were turning yellow brown. I ‘flushed’ all 4 plants with 2 gallons of water each. It seemed to take care of the problem. Plants were nice and green and had grown quite a bit. Flash forward approximately 2 weeks and the problem seems to be back. So, Using Happy Frog, PH should be acceptable…Using Fox Farm Trio ( very diluted) and my lights are the same. So soil good, nutrients good, lights good. Will try to attach pixx. My point is, when I was using my homemade soil mix, bag seed of unknown genetics and home-brewed lights, I had really decent success…now that I’m using all the ‘right’ stuff…I’m having problems I never had before ( so I don’t think it’s seeds, soil or lights.) Some help from someone that has a definite idea about this would be appreciated. Thanks.
Happy Frog soil out the bag not adding solutions is usually properly pH’d. When you add supplements, that solution will have it’s own pH that needs to be properly adjusted. If u just mixed a batch and poured, u probably have a lockout.
Thanks for the response, Purple&Gold. In my post, I mentioned that the yellow-brown spot problem happened before I added anything (about 20 days into the grow). Since I had not added any nutrients at all before this, I assumed the initial nutrients in the Happy Frog were starting to get depleted and more were needed. I watered with a VERY diluted solution (1/2 vs 6 tsp of Big Bloom …1/4 vs 2 tsp of Grow Big…and just a few drops of cal-mag), which is very mild compared to the chart or bottle. Since this did not help, I ran 2 gals of plain water through each pot, which ‘cured’ the problem for a couple of weeks. Now the problem has reoccured without any action on my part. From what I understand, this is not indicative of a lockout problem.
Did you spray anything or perhaps get condensation?
Have u perhaps gotten the plant wet? Those do look slightly like lensed water spots as well.
Logic led me to the lockout possibility.
20-30 days is about how long I get from a plant in Happy Frog. Possibly an extra week or so.
The deficiencies started, which would lead to one feeding.
Feeding a solution mixed correctly but not pH’d into range will drop the soils pH. Say the soil was at 6.5 exactly. Ur solution would be in the low 5’s if not adjusted. Pouring that solution into properly pH’d soil lowered ur rootzone’s pH level.
Now if u adjusted the solution all that is moot. Just an observation.
The flush after probably pulled it back into range, but subsequently it removed the nutrients in the soil. So another feed adjusted properly (6.4-6.8) would be the next step I took.
I appreciate the info. Guess I need to check the pH. Does anyone have any recommendations ( Amazon link, etc) for a cheap, accurate, reliable digital pH meter? (One that measures water and soil, if possible). Thanks.
This baby is $50 but efficient as all outdoors. Mines is 3 years old, and honestly Im ready to retire her (not for lack of working, more as a backup) and upgrade to the more expensive model. Worth EVERY PENNY

Not the combo kit. And it doesnt quite test soil, but it works for a slurry test and with solutions/runoff
Hey first mistake never follow instructions on nutes they say give nutes every water no. U only give nutes every other week. So say for instance u get dry 2 week ok one them water u will have nutes. Next water in that week no nutes. Don’t over nutrients. Give them breaks. Now only thing I will say that goes in my water every time is my veg bloom n that only a scoop.
Well I got my phone stick from the grow tent. N its does ph and ppm. Check it out
Very pretty buds !
Congratulations on the harvest, I have grown a couple of the fruity strains blueberry and girl scout cookie extreme. Blueberry being my favorite of the two.
Yup just did black Berry check my topic out
The banna was just the biggest I’ve done yet.
