    What are these spots and am I too crowded?

    Here are updates pics from running mid strength nutrients... looks like I can go back to normal strength, but I'm open to feedback. Guessing I should leave p/k boosters alone for the rest of the run to be safe. I don't want to lose any quality for minimal gains or stress them out any more than...

    Diy FOTOP grow board 280x900x2.0mm (L29.52"xW9.18")

    This is for a 4x4 and I am trying to replace my 600hps during the summer months and maybe complement during the winter months. I am still reading up, but I am thinking about going with a 4k spectrum. I like the idea of 2 320s and then adding boards, but why not add additional drivers with them?

    Diy FOTOP grow board 280x900x2.0mm (L29.52"xW9.18")

    Would 2 HLG-320s give you more wattage? I asked about reliability because I was wondering about how hard I can/should run the boards and if 1 600w vs 2 independent 300w drivers would create more/less stress. I guess that doesn't matter between the two setups but if you have any suggestions based...

    Diy FOTOP grow board 280x900x2.0mm (L29.52"xW9.18")

    I'm close to placing my first order. Would a setup of 2 HLG-320s be more reliable than 1 HLG-600 for two boards?

    What are these spots and am I too crowded?

    Alright. I'll get to it first thing tomorrow. I appreciate all the help trying to figure this out. I really want to finish these off right. Other than the damaged leaves, everything else looks good. I am using sunleaves "rocks" (superheated/expanded shale) as a grow medium.

    What are these spots and am I too crowded?

    I'll take a look when the lights come back on. Some of the leaves are purple at the petiole but I'm not sure how widespread. I dont remember the leaves being leathery though... maybe the chem 91 if any. I haven't supplemented yet other than adding the bembe. I was thinking of adding magnesium...

    What are these spots and am I too crowded?

    Yup, that's it... combined is 7-6-11 and I mixed 28ml grow, 75ml micro, and 113ml bloom to a 40 gal reservoir (25% strength of mid bloom recommendation) should be 325 PPM. I added half a tsp per gallon of the bembe (recommendation is 1-2 tsp). Thanks for the link. I'll read up on it tonight.

    I stepped out for a second but I will check it out when I get back

    What are these spots and am I too crowded?

    These leaves for example don't look like they are burned by the nutes/light.

    What are these spots and am I too crowded?

    The nutrient chart lists between 5.8 and 6.2. I usually start low because it creeps up, but it has been staying right at 6.0 when I set it.

    What are these spots and am I too crowded?

    I am using green planet GP3 at 25% strength for the last two weeks following their nute chart in terms of npk. Ph is consistently at 6.0. I am using tap water to top off. Only supplement I added was bushdoctor bembe which is a blend of carbs. I'm looking and some of the impacted leaves aren't in...

    Do you see any signs of calcium or magnesium deficiency?

    What are these spots and am I too crowded?

    Yeah, I wasnt expecting as much stretch as I got. The light is only really strong in a couple of places. I am getting 40000-60000 lux in most areas. When I flushed the 91 chem seemed to respond but I never had issues with the other two. I also switched out a bulb that had dimmed out a bit. I...

    What are these spots and am I too crowded?

    I am running a 600w and I know there's too much light (around 80,000 lux in some areas). What should I do? Would a PK booster be a bad idea? What strength nutrients should I go with at this point?

    What are these spots and am I too crowded?

    Not sure of the canopy temps just that the overall temperature in the tent is 81 degrees. The tops are 12-18" from the bulb but about 6-8" from the glass of the reflector. I put my hand underneath and it doesn't seem too hot, but I'm not sure how accurate that is. The leaves that are affected...

    What are these spots and am I too crowded?

    As an update, I came back and noticed more spots, browning and yellowing. The second and fourth pictures are new damage to the boss hogg and amnesia. The first picture is the chem 91 which seems maybe a little bit better, but not really. I want to add a PK booster since I'm about 3 weeks from...

    What are these spots and am I too crowded?

    thanks for the update and descriptions... i am away until this weekend but will try to characterize when i get back home. the boss hogg is way stinkier/more flavorful than the 91 so far. and the amnesia is also super potent with major trichomes extending out on the fan leaves... i'll shoot some...

    What are these spots and am I too crowded?

    How long should I flush for? It's been three days with cyco kleanse and I leave tomorrow for a week. Would 4 days be too short and would 12 days be too long?
