i have my t5 on half strength, can't be burn.
Ya, I would do that along with a bit more N, just my opinion..... I’m no pro
That’s what I would do along with giving it a little bit more food
think mag,,starts in lower leaves ,, the veins remains green while the rest of the leaf turns yellow, exhibiting chlorosis, the leaves eventually curl and then die,,,the edges of the affected leaves feel dry and crispy,, as it continues it moves from the lower to middle to upper eventually growing shoots change from pale green to white
he said it was new growth, not old growth, which is what makes me hesitate to just say Mag
the top of the plant is "usually" new growth,,,,,so yeah
and this info is coming from the growers hand book,, has pretty pictures and all
Cal/mag and food, is she in a big enough pot. Root bound does weird shit

Calibrate your ph meter then check the PH. There are several things going on
Stick to the basics, you’ll get through it.
Week6 of flower, could be kinda normal
A picture says 1,000 words...so they say.
This is a first run of Grease Monkey, I obtained it via clone from a reputable source here in Portland Oregon. It is giving me issues, issues that have have never encountered before. The pictures will explain all details of growing conditions. I am getting floating algae in my filters and on air-stones. The roots have remained white for the time being. I use Current Cultures complete line including UC Roots. Also included in my feeding program is a product called Mycostop. I have been using these products since they were introduced some years back. At that time, they were being manufactured by Clean Grow, whom I highly recommend. The issue seems to be a fungi infection in the root zone, but again, I am not 100%. I am getting what looks like a combination of deficiencies like magnesium, calcium and a hint of potassium. I have dealt with rot issues (pythium) before, this is not it. Absolutely no light penetrating into the nutrient solution and temperatures are always consistently at target. The only thing I can think of is the introduction of mold spores via the air-pumps. There are two AL-80s and one AL-20 constantly oxygenating the nutrient solution.
Like I said, this is a first run with this particular genome type. I have experience with the lineage but am not seeing any positive response to anything that has worked on those strains in the past. I have a friend that works at OHSU as a microbiologist, she tells me the cyanobacteria cannot survive with absolutely no light. So I have marked that off of the list of possibilities. Any ideas of how to positively identify the substance and how to treat it, would be much appreciated. I cannot introduce beneficial bacteria that cannot sustain at 2ppm of Hypochlorous Acid, as I use UC Roots. I have questions about the proper strength of Physan 20 in RDWC. Does it work as described by the sales reps?
Please, pummel me with questions and answers!
More photos. There are three Bluelab Guardians and a PH controller connected to the system. Two of the guardians monitor the root zones at either end of the system and the ere is one monitoring the control bucket. The incoming water goes through a tall boy and a 1200gpd UV sanitizer.
