Hey guys,
First time grower possibly experiencing some nutrient burn. I’m at the end of week 5 of flower with my haze and sour in a 4x2 indoor tent using 5gal DWC buckets. I changed the reservoir adding bloom (aka Shine via hydroponic research) to my base (grow- tap/hard) when I flipped them to 12&12. I followed the difficult feeding chart on the hydroponic research website. I was just monitoring the ph at that time and adding my bloom nutes accordingly. I started to get some burn/browning and curling at the tips. I pruned the dead leaves and scaled back the nutes and gave it some fresh reverse osmosis water. With no resolution and new leaves forming brown tips I went to my local hydro store and they recommended the blue lab conductivity pen with some other additives if my EC/PPM was under 2.6 EC (1300ppm/500). Now the whole EC scale was kind of confusing at first but from some homework I guess EC is the standard and also what my nute feeding chart was going by… but Holy fuck… I checked where I was at and my haze EC was at fkn 4.8 (2,800ppm/500)! Almost certain that’s equivalent to nut burn. Sour was even worse at 5 EC (3,000ppm/500). So now I’m like what the fuck do I do? I obviously don’t want to add more nutes and increase the EC. So I binge read almost every thread pertaining to nute burn and flushing the whole system and what seems to be a very controversial topic: flushing with or without nutes. Now I know this late in flower they need less nitrogen and increased amounts of phos. So far I flushed the haze completely draining the 5 gal bucket how one would drain a fish tank and simultaneously adding fresh water to the res. I then got a spare 5gal bucket and added fresh water and changed out the res. I was told to add nutes slowly and keep the EC/PPM low. Idk if that’s the right thing bc I know the EC and PPM was so high I could just put my plant into shock by changing the waters EC so rapidly. I’m an icu nurse so I know when someone’s electrolytes are to high or to low they have to be replaced or depleted slowly or the side effects could be detrimental. Before I go and do the second plant I just wanted some feedback. I appreciate any and everything. I’ll attach some pics of the leaves. Thanks in advance!
