Hello, hope you guys can help. Having trouble with some 3 week old autos now. Some girls leaves are starting to hook downwards and edges are cupping. So my tap water Ph is 8.5 naturally. As a test I watered one plant today with just plain tap water at 8.5. run off came out at ph6. That seems...
I think I will adjust tap water to ph6 and run that through the girls, hopefully with the run off around 6- 6.5 the actual soil ph should be in the right place.
Hmm.. so what you mean is 6.5 is optimal but within 6-7 will suffice for the uptake of calcium? I've been referring to a lockout chart for guidance but Calcium seems available at what my ph is (I'm guessing around 7.5 based on tests). The only nutrients that seem unavailable are boron, iron and...
Also fed one ph 7 adjusted and the run off was between 7- 7.5. So I'm guessing my PH is too high and what it seems is the symptoms I'm seeing are likely boron and iron deficiency due to lockout. Is that reasonable? I'm ruling out overwatering as the pics were taken a day from being bone dry...
I measured it today. Using tap water. Didn't adjust it. I added .5ml/l plant magic magne-cal (half suggested does), figured it wouldn't do any harm. PH just below 8.5 After watering and measuring run off PH 7.5 give or take.
Would really appreciate some help with this. its day 30 of my girl scout cookie auto grow. Older fan leaves have rapidly started to yellow over the last few days. I fed them 1/4 does of plant magic magne-cal with 1.5ml/L a+b advanced nutrients sensi bloom ph perfect. soil is plagron light mix...
I've also noticed that the part of the fan leaves that were overlapped by another fan leaf
Do not have the yellow colouring on them only part of the leaf exposed to light. I'm totally confused.
Ok so over the last week or so I've noticed my fan leaves on most of my plants start to yellow real fast. I know they should yellow towards harvest but I have almost another month of flowering so this is too soon. Also the top yellow leaf in the picture literally turned that yellow over night...
Cheers justugh that's some comprehensive info there. I like the idea of the ir insulation, it seems pretty cheap and will definitely give me piece of mind. Thanks for the shout out on that one man I really appreciate it.
Hi ROI,
Just wondering what to do with regards to heat output from a loft grow. The loft is not insulated at all its just tiles but what I'm looking to do, depending on the measurements, is put either a 4x4 tent with a 600w in there or a 4x8 with 2 600's.
First question is would the heat of the...
