What’s up DGC,
I’m trying to help a fellow beginner with an issue his plants are having. He’s growing autos from ILGM about two weeks into flower using a mix of big roots in the bottom of his pots and FFOF on top, fox farm grow big and tiger bloom, recharge. He’s growing under an HLG300 and has more recently started adding cal-mag. To me it looks to be a calcium deficiency that he is dealing with so the question is what should he do from here? Assuming he’s using cal-mag by the bottle recommendations is it safe to mix stronger to get more calcium in there? Maybe it’s not calcium deficiency? Help! Thanks DGC and grow on!
check for bugs under the leaves and i’m not positive but looks like you are light on potassium.
use the bottle recommendations, 1st big mistakes that are made ,is, More is not better.
i personally got away from the bottle i pretty much use worm castings top dress and recharge every 7 days. add cal as needed per bottle info. and water with 7.0 well water.. recharge and flower fuel in bloom…
If he’s running an AUTO it might be too late to handle that Magnisium deficiency……to be honest dude.
The key with Cal Mag is to use it earlier in flower mixed with you nitrogen based nutrient so the plant is stocked on its reserves when you go to flip to flower.
Since you are just starting to add in flower your plant will be struggling the rest the way. I would do full dosage but no other nutrients…let that absorb then do the smallest amount of normal nutrients mixed with half Cal mag and do that until it seems healthier…..it won’t fully go away though and you may not gonna get alot of trim.
Guru also suggest Magnisium Sulfate salt.
Look out for russet mites, they cause lockout problems. You’ll need a loupe or some kind of magnification device to identify them, but you can also see them with the naked eye buy looking very carefully and slowly. Check the top soil for just barely noticeable bugs crawling around and try to get some to put under magnification. If you have russets lay off the nute and lay on the nuke.
This look like typical shit for fox farms nutes. The amounts they advise are retarded. I had nothing but this kind of bullshit when I was on them. Are you shaking the holy fuck outta the bottles? I would stop all of that and do recharge. Calmag is awesome but what is the waters starting ppm? Is he adding the cal mag 1st? ALWAYS BEFORE. I don’t see bug issue. Spider mites don’t suck dots so far apart from each other. Russet mites are the silent killer cause they don’t leave marks. You see a overall “lacking”. This seems pretty specific. Stop all. Flush with recharge and call yo mamma in the morning
I’m with Sunny on many points here. First off it doesn’t look like bugs to me. Secondly I notice this shit with my fox farm stuff and shake the shit out of everything now. Slowly switching to nectar for the gods so no more fox farm, botanicare or general hydro for me. So what this looks like a calcium deficiency to me. If I’m wrong JMystro will hopefully step in and educate me. Adding more cal mag is not the solution if you already have. As she said check PH to make sure you are taking up inputs already in there. Sunny is also right about adding cal mag before nutes. If you are running silica mix that first then the cal mag. I petsonally have stepped away from a one bottle calmag and add them separately now. Definite learning curve. Good luck
I agree with Sunnyinbectopia and Rasufa, that’s a typical FF looking plant. Foxfarm 3 part has way too much Nitrogen all the way through especially in flower. Nitrogen blocking Calcium out and that funky green color is Foxfarm trademark. I never ran more than 3/4 their recommended nutrients with photoperiods and cut out Grow Big about 1-2 weeks before flush.
I don’t know your pot size and water/feeding schedule but I would flush with water phd to +/- 6.2 using 1/2 water volume to pot size (3 gallon pot = 1.5 gallons of water) check ph and EC and adjust from there. Water in ph water, Calcium and Recharge according to runoff test up or down targeting 6.2. The soil as posted should have an abundance of NPK nutrients til next feeding assuming they are reasonable feeders and not in an overly large pot. Then go back to feeding as usual, I would suggest 3/4 rates. That’s based solely on my experiences with Foxfarm, in my garden, under my conditions and may not be the answer for you but a ph and ppm check is in order anyway. Happy Growing 🙂

Popping new seeds is almost as exciting as opening your new girls bra for the first time and seeing what pops out.
Everything that I know about botany and horticulture I learned from cannabis, the rest I learned from the DGC.
So we are both using the FF trio and feeding once a week at 1/4 to 1/2 the recommended and both using recharge. The main difference between us is that he started using his calmag after he was already in flower and I started using it as soon as I started feeding at around 3 weeks. We’re also both using 5 gal fabric pots. I always shake the hell out of my bottles when I feed but I don’t put the calmag in with my regular nutes, I add it on a different day with recharge and calmag only, mixing in calmag first. Is this an OK method? I have 4 autos growing using nearly the same inputs he is using and I’m not having any issues at all and I’m within 10 days or so of harvesting. I appreciate everyone’s answers on this! Just trying to get my dude fixed up.
