Theyre curling upwards which isnt good! Maybe a sign of Magnesium defic. I think, I read somewhere - I think actually here on the pests,probs and disease section on here and yeah - WATER?? How often are you watering?? She doesnt look happy duz she and she s flowering too... Shit I havent seen a case this bad for a while.. I am not sure as to what your PH is, But check that too mate as if its not in the appropriate range so nutes maybe locked out. You want your soils PH about 6.2-6.7 this is apparently a good range for the plant to absorb the nutes it needs.
ARE YOU FEEDING THE PLANT ANY NUTES? IF SO, WHAT - AND HOW MUCH? Hope it sorts out for ya mate... Best of luck. Smokemup
Jimmy, I've been growing autos (soil) in a tent for the past 3 years, and I have walked in your shoes. You have a couple of issues going on micronutrient lockout and nute burn. What type of soil are you using and what is the soils ph level? I would completely lay off the nutes and get your soil ph to 6.5, depending on the severity of the lockout you may see improvement within 4-5 days but may take as long as 2 weeks, thus affecting your yield. I notice a circulation fan inside your tent pointing down towards the floor, when you circulate air down to your pots it will dry your roots out real fast, the best location for this fan would be between your reflector and canopy (top of plants), all you need is your lower vent flaps open for good air circulation down at floor level.
Hope everything works out for you!
THanks for the reply
About the fan. In which direction shoud it be pointing. upwards or downwards ?
I have a standard flower soil mixed with hydrograins.
Im going to try now to put flush them with ph 6.5 water and see what happens. I think that the small plants that are the most damaged ones are def. overfeed.
I dont know what ph level the soil is and i dont have any thing to mesure it with.
About what Jimmycricket said about the overhating that should not be a problem since there is never more than 22 celcius in my tent. As you can see the all the pictures have a yellow tone to them becuse of the bloom HPS.
Your fan should point straight to the opposite side of the tent, just above your plant tops, you want your plants to receive a gentle breeze. Your temp should be monitored at your plant height as well.
I'm not a big fan of flushing, I never really felt the need to do it. I water slowly until roughly 10% flows out the bottom of my grow bags.
You gotta be able to measure your ph both the water and soil, otherwise your just guessing sometimes you may get lucky but most times you won't. For me, my soil mix that I use is always between 6.0 and 6.8 so I simply keep my water at 6.5. I only check my soil at the beginning of each grow just to be confident it falls between the specified range, now if I see an issue with a plant develop 1st thing I do is check my soil ph, the earlier you catch a problem the better, 99% of the time it's always ph related.
best of luck bro!
