Minor deficiency noticed today.

[Craigc1509]

-Problem: On two plants I notices there are lower branches that are pale green and the leaves crumbled away when i touched them,papery. A leaf that I found looks like a Phosphorus def. Also note that the branches in question are tiny and could easily be lopped off, I just figured I would keep them on for the little extra bit.
-Medium/grow method: Soil; Fox Farm Ocean Forrest.
-Feed and supplements used: Fox Farm Trio.
-Water source: Clean PHed tap water anywhere from 6.4-6.7.
-Strain and age: Gold leaf, 12 weeks, Friday is 5 weeks into flower.
-Climate: 75 degrees during the day and 68 at night almost every single night give or take a degree or two.
- Light used: 2-Electric Sky ES300 LEDs
-Additional info: I've noticed when I switched to flower I had quite a bit of lower leaves wilt away but they were extremely bushy and not getting light, now I have lollipopped a bit, as well as defoliated, given them time to recover and now I notice the leaves crumbling away. The lower branches were always a lighter color but nothing noteworthy until I noticed today.

Here's the plant as a whole with another gold leaf for comparison just to its right. they both are doing extremely well.

I don't see any big problem to worry about.You have a few bad leaves but other than that they look good.Just keep feeding bloom nutes and cal/mag and and you should be fine.

They progressed a bit over the night but they're due for a feeding today.

known to be Ph variable...............and the soil, very variable in Ph.............. i would do a 200ml run off test, and see if the medium is in the range 6.0 to 6.5Ph.......................and an Ec below 1.5..........

75 degrees during the day and 68 at night

75f = 22c & 68f = 20c !!.................. these are tropical plants, that like a soil temp of 22-24c ! and an air temp 26 to 29c and an RH around 35% to 45%.........................your grow temp due to LED's is way to low to forfill those flowers................... can you get an infra red hand held temp gauge ?/.........................to check your leaf and soil temps ??.................... you need your LED at 60cm above plants to get best light penetration and lux.......

turn down your fan, to slow hot air removal, lights on, and at lights out, to keep culture temps up at root temp lights out, a 1kw floor thermo controlled fan on a timer, on at lights out set at 26c............trial and error on the fan trigger setting... hope that is some help.................. best of luck for the finish.......... there is a lot of plants with little light power, is why they are stretching for lights...............recomend a 600w HPS in with LED to finish flowering and raise lights on temp......................... will off set the use of the heater below, lights on temp, which has also got to be raised lights on........................ALR

stay with these Ph ranges if pos, your root temp is dependant on nute uptake..............ALR
